Time of issue:2026-03-06
I. Product Overview
TA75A-WD- JDSB thermoplastic elastomer (TPE) material. This material is a high-performance formulation specifically designed for bonding PC/ABS, featuring excellent adhesion, outstanding abrasion resistance, and a comfortable tactile feel.
II. Details of Application Cases
- Application components: Scissor handle
1. Background and Customer Needs:
The customer requires an overmolding material for high-end scissor handles, with the primary requirements being:
- High adhesion: The ABS plastic handle substrate must be firmly bonded with no risk of delamination.
- Excellent feel: Provides a comfortable, smooth tactile feel, enhancing the product’s premium appeal and user experience.
- Scratch- and wear-resistant: The material must have excellent wear resistance to ensure that its appearance remains intact even after prolonged use.
- Weather resistance: Meets aging resistance requirements for everyday use environments.
2. Materials Development and Implementation Process:
- Preliminary plan: Based on the customer’s requirements, we first recommended the model: TA75A-WD-30 The TPE material meets the requirements in terms of hardness, feel, and basic encapsulation performance. After testing the sample, the customer expressed approval of its feel and hardness.
- Issue Feedback: Customer feedback indicates that, after being left for 1-2 days, injection-molded parts made from certain colors of material have begun to show... Color difference (color deviation) Phenomenon that affects the consistency of product appearance.
- Solutions and Optimization: The technical team conducted formula optimization and process adjustments to address this issue, developing an improved model. TA75A-WD-JDSB The new formulation enhances the dispersibility and stability of the pigment powder, completely resolving the issue of color variations that occur after storage.
- Final result: Customer trial TA75A-WD-JDSB Afterward, it was confirmed that the color difference issue had been resolved, all performance metrics met the requirements, and batch import was successfully implemented.
3. Case Value:
This case successfully addressed the issue of rubber coating on scissor handles. Hand feel, adhesion, and abrasion resistance and Color stability Comprehensive requirements were met. By responding swiftly to customer feedback and conducting technical optimizations, we demonstrated our capabilities in materials development and problem-solving, ultimately helping end customers enhance product quality and market competitiveness.
III. Summary
TA75A-WD-JDSB is a high-performance, coated TPE material with excellent overall properties. Its successful application demonstrates that it can meet both stringent requirements for high adhesion and superior hand feel, while also satisfying demanding needs for stable color appearance. This material is also suitable for other applications—including consumer electronics accessories, household items, and handles for personal care products—that require coating ABS or PC materials.
