3. Application Background

  • Terminal demand : The wheels of the toy robot must have Wear resistance (Long-term rolling without wear), Anti-slip performance (Ensuring motion stability) and Rubber-coating process compatibility (Firmly bonded with ABS substrate.)
  • Industry Pain Points Conventional TPE materials are prone to issues such as insufficient adhesion between the rubber coating and the base material, poor hardness compatibility, or inadequate wear resistance.

 


IV. Development and Implementation Process

  1. First sample failed.
  2. TA65F-11 The rubber coating has poor adhesion and insufficient bonding strength with the ABS substrate, posing a risk of delamination.
  3. TA68H-01 The hardness is slightly high (exceeding the customer’s required range of 64-66A), which affects the wheel’s flexibility and feel.
  4. Optimization Plan and Secondary Sampling
  5. Selected TA65H5-JQECL
  6. Adjust the formulation to enhance the encapsulation performance and ensure strong chemical adhesion to ABS/PC substrates.
  7. Precisely control the hardness to 64–66A Shore A, balancing flexibility and support.
  8. Achieve rapid mold filling and enhance production efficiency through a high-flow design (melt index of 21 g/10 min).
  9. Test validation
  10. Wear resistance test Simulates long-term rolling scenarios with no obvious wear marks on the material surface.
  11. Slip resistance test Verify sliding resistance on smooth surfaces to meet toy motion stability requirements.
  12. Coating Adhesion Test The peel strength meets the standard, with no delamination or cracking observed.

V. Case Outcomes

  • Customer Feedback TA65H5-JQECL has successfully passed all performance tests and demonstrates good stability in mass production.
  • Strengths Summary
    • Process adaptability : Injection molding at 200℃ boasts high efficiency and a yield rate of over 98%.
    • Functionality compatibility Combines wear resistance, anti-slip properties, and a comfortable feel in one, meeting both toy safety and user experience requirements.
    • Cost-effectiveness Compared to imported materials, costs have been reduced by 15%, and the delivery cycle has been shortened by 30%.

 


VI. Expanding Application Potential

Thanks to its comprehensive performance, TA65H5-JQECL can be extended to more fields:

  • Consumer electronics Phone case, handle grip with rubber coating (wear-resistant and non-slip).
  • Industrial accessories Conveyor belt rollers, seals (weather-resistant + high elongation).
  • Sports equipment Fitness equipment grips (comfortable touch + tear-resistant).
