Adoption of Chinese-made PI Tape for Heat-Resistant Process Film | Cost Optimization via Just-Spec Specifications

While domestic high-spec PI tapes offer more than adequate performance, they are often over-engineered for specific applications. By selecting a "just-spec" grade from a Chinese manufacturer that perfectly matches the application's needs, and verifying its quality through our Shanghai base, we achieved both cost reduction and quality maintenance. Deterioration of the Cost-of-Sales Ratio for Heat-Resistant Process PI Tapes and the Necessity of "Just-Spec" Optimization Cost reduction is required for PI tapes used in heat-resistant processes. However, since high-spec options are excessive for this application, the goal is to select an appropriate grade.Previously, domestic high-spec PI tape was adopted, but it was over-engineered for the specific application.●Context of emergence: Cost improvement phase.●Primary impacts: Deterioration of the cost-of-sales ratio, decline in price competitiveness. Why High-Spec Products are Excessive: The Gap Between Actual Application Requirements and Specifications Continued adoption of high-spec products serves as a cost-up factor. For actual applications, an acceptable/usable level is more than sufficient.●Specific evidence: Physical property comparison of existing materials and processing tests. Countermeasures Attempted So Far and Their Limitations Price reduction negotiations for domestic high-spec products (reached limits), and substitution with alternative films (insufficient heat resistance).Based on these limitations, we adopted the following approach as a more drastic/fundamental solution. Solution Approach: Application-Specific Grade Design × New Chinese Supplier Development × Quality Verification via Shanghai Base Through the development of new foreign suppliers + collaboration with overseas bases, we adopted PI tape with cost suitability that perfectly matches the application. STEP. 01 Supplier Development Evaluating multiple Chinese-made PI tapes STEP. 02 Downgrading Proposals Setting necessary and sufficient specifications for the application STEP. 03 Local Collaboration Quality verification and local procurement via Shanghai Base Fujichemi Trading's Supply System: Head Office × Shanghai Base This solution is achieved through the division of roles across multiple bases.・ Head Office / Domestic Sales: Customer window and cost proposals・ Shanghai Base: Local manufacturer coordination and quality verification●Supply System: Stable supply of overseas procured products.

Thermal Barrier Paint Solution to Reduce Factory Electricity Bills in Thailand | Arranging Local Application Partners | Collaboration Across 3 Bases: China, Thailand, and Vietnam

In the Thai manufacturing industry, continuous increases in electricity rates and prolonged dry seasons have caused factory electricity bills—primarily for air conditioning—to squeeze profits. Focusing on the application of thermal barrier paint to roofs, we provide one-stop support ranging from electricity bill reduction simulations to the arrangement of local application partners and localized currency quoting. As a realistic solution to lower running costs with low investment and short construction periods, this has already been adopted by multiple Japanese factories. Soaring Electricity Bills in Thailand: What Was Happening Inside the Factories? Electricity rates in Thailand have undergone repeated increases due to fuel cost adjustments, making the pressure on production costs a chronic issue. Especially in factories with large roof areas, coupled with the prolonged high temperatures of the dry season, air conditioning systems run at full capacity constantly, inflating annual electricity bills to a level that demands executive-level management decisions. On the other hand, upgrading power reception and transformation equipment or installing solar power presents high hurdles regarding initial investment, construction periods, and the shutdown of existing facilities, leaving many facilities unable to take action."We want to lower our electricity bills. We also want to deliver results in the context of SDGs and CO2 reduction. However, we cannot commit to capital expenditure on equipment."——We hear these exact concerns from numerous Japanese factories operating local subsidiaries. Why Aren't Electricity Bills Dropping? Radiant Heat from the Roof Keeps Air Conditioning Running Constantly The root cause revealed through on-site inspections and roof surface temperature measurements is a structural issue: the roof and exterior walls lack heat-insulating performance, allowing radiant heat to flow directly into the interior. In some cases, the roof surface temperature exceeds 70°C during the day, and this heat warms up the ceiling space and indoor air, meaning the air conditioning cannot keep up no matter how much it cools.Furthermore, factory buildings in Southeast Asia often have outdated insulation specifications, so upgrading air conditioning units alone rarely provides a fundamental solution—this is the main reason why many hesitate when considering upgrading existing facilities.The basis for identifying this cause comes from cross-referencing the following two points:・Reviewing current electricity bill data provided by the customer・Measuring roof surface temperatures and checking roofing materials during on-site inspectionsBy matching these two datasets, we can conclude with near certainty that "heat inflow from the roof is the dominant factor." Countermeasures Attempted Thus Far and Their Limitations Countermeasures already attempted by many factories share the following common limitations:・ Adjusting HVAC operating hours: The effect is limited, and the system still faces high loads during production hours.・ Considering heat-insulating film application on the roof: Frequently abandoned due to hurdles in cost and construction periods.・ Considering retrofitting insulation materials to existing equipment: Requires halting existing equipment during construction, resulting in too great an impact on production.Given these limitations, thermal barrier paint emerges as the realistic solution—a move that "reduces heat inflow from the roof without stopping existing operations." Solution Approach: Thermal Barrier Paint × Electricity Bill Simulation × Local Application Partners By focusing on top-coating existing roofs with thermal barrier paint and providing the following three components as a complete package, we lower the hurdle for customers to make the decision to "give it a try." STEP. 01 Sourcing Alternative Materials and Replacements We perform a matrix comparison of both Japanese and local manufacturer products based on required performance, roof material compatibility, and cost to select the optimal thermal barrier paint grade. Focusing primarily on products with a proven track record in Thailand, we also obtain evaluation data from cooperating manufacturers as needed. STEP. 02 Presentation of Electricity Bill Reduction Simulations Based on current electricity bill data, HVAC operating hours, roof area, and insulation specifications, we will estimate the post-application electricity bill reduction effects and the payback period. Visualizing the "numbers" necessary for management decisions significantly accelerates the internal approval speed. STEP. 03 Selection of Local Construction Partners and Quotations in Local Currency Leveraging our Thai base as a starting point, we select reliable local application partners and optimize pricing and lead times via local currency quoting. We also propose process designs that minimize the impact on your production, including night/weekend application and split-phase application block by block. FUJICHEMI TRADING's Support Framework: A Powerful Triad of Japan HQ, Thai Base, and Cooperating Manufacturers This solution is realized through a clear division of roles among three parties: Japan HQ (Sales/Technical), our Thai base, and cooperating manufacturers.・ HQ (Sales/Technical): Selects coatings / Prepares electricity bill reduction simulations / Supports decision-making for adopting companies・ Thai Base (Local Subsidiary): Conducts on-site inspections, selects application partners, and provides local currency quoting/contracting / Manages application and construction / Provides after-sales support・ Cooperating Manufacturers: Supplies thermal barrier paint / Assists in grade selection / Provides evaluation data● Supply Framework: Local inventory support and small-lot application are available. This enables a small-start introduction where you can first test the effects on a single building before rolling it out across subsequent buildings. Results of Adoption: Simultaneously Achieving Running Cost Reductions and Workplace Environment Improvements We have received the following qualitative and quantitative result reports from adopting companies:・ Reduction in factory running costs (electricity bills): Achieved a reduction (▲) in electricity bills based on actual customer data.・ Lower indoor and roof surface temperatures: Stabilized summer production efficiency due to improvements in perceived temperature.・ Visualization of the payback period: Increased the precision of management decisions, accelerating subsequent rollout evaluations.・ Rollout track record: Cases exist where introduction to a single building led to expansion across additional buildings and sister factories.● Introduction Lead Time: Rapid turnaround is possible from the initial consultation through estimation to test painting. Anticipated Ripple Effects and Rollouts: 3 Returns Beyond Just Electricity Bill Reductions The effects of adopting thermal barrier paint extend far beyond electricity bill reductions. Please utilize these cascading ripple effects triggered by "heat mitigation" as supporting material for your internal proposals.1. Workplace Environment Improvement → Lower Turnover Rates and Higher ProductivityBy mitigating the extreme heat directly beneath the roof, the workload on workers during hot seasons is reduced. As securing and retaining operators is a pressing management issue in Thai manufacturing sites, improving the workplace environment directly links to lower turnover rates and enhanced productivity.2. Contribution to SDGs and CO2 Reduction ReportsElectricity bill reductions can be directly quantified as carbon emission reductions, leading to immediate score improvements in CSR and supplier evaluations. In an era where global headquarters' procurement standards closely scrutinize "suppliers' CO2 reduction track records," leaving behind quantitative data holds great value.3. Extending the Service Life of Rooftop EquipmentLowering the roof surface temperature reduces thermal stress on outdoor HVAC units and solar panel peripheral equipment, which can be expected to extend equipment life. This creates a double benefit: electricity bill savings combined with delaying future equipment replacement costs.Furthermore, for customers who establish a proven track record of introduction in Thailand, we can also support the horizontal rollout of identical proposals to your factory bases in Vietnam and China. Differences from Competitors: Why Choose FUJICHEMI TRADING? Compared to competitors that only sell coating products (paint manufacturers' direct sales and local chemical trading companies), our unique strength lies in our ability to provide a seamless, end-to-end service encompassing "electricity bill simulations + local application partner arrangements + local currency settlement." Our network, which bridges Japanese-level quality and localized cost structures, is the reason we continue to be chosen.・Difference from Manufacturers' Direct SalesThey do not provide simulations or arrange application partners, requiring customers to handle these arrangements individually.・Difference from Local Paint DistributorsWe offer selection based on Japanese quality standards, along with technical support in Japanese and proposal materials tailored for executive-level management. Product Information & Specifications Overview The main specifications of our proven thermal barrier paints offer a choice of multiple grades depending on the application and roofing materials.

FAQ (Frequently Asked Questions) Are there any restrictions on the roofing materials? Our solutions support major roofing materials including metal, concrete, and slate roofs. Since the optimal grade varies depending on the material and shape, we will provide a proposal after an on-site inspection. What is the estimated payback period? It varies depending on the roof area, electricity cost rates, and HVAC operating hours. If you provide your current electricity bill data, we will run a simulation to calculate a specific payback period for you. Can the application be performed without stopping existing production? Yes. We will propose a process design that minimizes the impact on your production, including night application, weekend application, and split-phase application block by block. How can the effects be measured? Measurement is possible by comparing roof surface temperatures, indoor temperatures, and electricity bills. We also support you starting from the selection of representative measurement points. Is support available at overseas bases outside of Thailand? Yes, we can roll out identical solutions at our bases in Vietnam and China (Shanghai). For customers with multiple locations, we can also propose the standardization of specifications across all bases.
