Temperature-Dependent Sheet HUMOFIT® | Reducing the Feeling of Pressure with F+BAND, a Fixation Band for Medical and Sports Applications

Balancing "rigidity at room temperature" and "flexibility at body temperature," which is difficult with conventional fixation materials—with F+BAND applying the temperature-dependent sheet HUMOFIT®, we have simultaneously achieved reduced tightness when worn and ensured breathability. This solution also looks toward horizontal expansion into the medical, sports, beauty, and wearable device fields. The Issue of "Tightness from Fixation Bands" Occurring in Medical and Sports Fields In medical and sports applications, there was a demand for a material that "fits the body without a feeling of pressure" as an alternative to fixation bands and bandages for arms. With existing materials, it is difficult to balance moldability and a snug fit.It was necessary to switch between hardness and softness depending on the situation, which was difficult to address with conventional fixation agents and tapes.● Scenarios where this becomes apparent: Improvement of existing products. Needs became apparent in situations such as exhibitions.● Main impacts: Discomfort when worn → lower continuous use rate, deterioration of workability in medical fields, and difficulty in differentiation from competitors. Why Existing Materials Do Not Fit: Physical Properties That Cannot Balance Room Temperature and Body Temperature The physical property limitations of existing fixation materials (plastics and rubber). They cannot balance rigidity at room temperature with flexibility at body temperature.● Grounds for identification: Interviews with existing clients and at exhibition booth displays. Countermeasures Attempted So Far and Their Limits Elastic rubber bands (feeling of tightness remains) and cast-type materials (heavy and difficult to handle).Based on these limitations, we adopted the following approach as a more fundamental solution. Solution Approach: HUMOFIT® Application × Die-Cut Shape Optimization × Perforating Process to Ensure Breathability Applying and developing the temperature-dependent sheet HUMOFIT®. Optimizing breathability and fit through material grade changes combined with die-cut shapes and perforating processes. STEP. 01 Material Grade Change Re-selecting the HUMOFIT® temperature-dependent sheet for medical applications STEP. 02 Die-Cut Shape and Size Adjustment Repeating evaluations with fixation band shapes STEP. 03 Perforating Process Ensuring breathability and suppressing stuffiness Fuji Chemi Trading's Supply System: Headquarters × Partner Manufacturers This solution is established through the division of roles among multiple bases:・Headquarters / Domestic Sales: Customer window and exhibition collaboration・Partner Manufacturers: Supply and physical property data of the HUMOFIT® sheet● Supply System: Prototyping response with multiple variations of shapes and sizes. Results of Implementation Achieved function and performance improvements. Tightness when worn has been reduced, improving the feeling of use in medical and sports fields.● KPI Candidates: Improvement in sensory evaluation of tightness / Extension of wearing time / Reduction of rashes and stuffiness at the wearing site.● Implementation Lead Time: Commercialized by repeating prototype evaluations of shapes and perforation layouts. Anticipated Ripple Effects and Horizontal Expansion The benefits of implementing this solution extend beyond solving the primary issues. Please utilize this as material for internal and management proposals.・Horizontal expansion into prosthetic devices, supporters, and bands for pets・HUMOFIT application into helmet linings, sports protectors, etc.・Development into beauty and wearable devices (such as sensors that adhere tightly using body temperature)・The message "Deforms with body temperature" has excellent compatibility with technical and health media Differences from Competitors: Why Fuji Chemi Trading is Chosen Trading companies dealing only in single rubber or resin items have thin application know-how for temperature-dependent materials. Fuji Chemi can propose "HUMOFIT material × cutting shape optimization × perforated breathability design" as a package proposal.

Horizontal expansion into prosthetic devices, supporters, sports protectors, etc., is possible. Can you also propose this for the beauty and wearable device fields? Application to beauty equipment, wearable sensors, and other purposes that tightly adhere using body temperature is possible. How do you ensure breathability? Breathability is ensured through perforating processes (H type). The size and layout of the holes can also be customized. Can the die-cut shape be customized? We can accommodate customization of die-cut shapes, sizes, and perforation layouts. Is it possible to request samples? We can accommodate sample supply. Please let us know your requirements.
