Natural Color Over Molding Thermoplastic Elastomers (TPE) Suppliers and Factory in China
Product Introduction
Engineered for secondary overmolding, this TPE grade offers a broad hardness range from 25A to 80A, providing designers with exceptional flexibility to achieve anything from a soft, cushioned grip to a more rigid feel. Its key advantage is the availability of customized formulations that ensure strong, permanent adhesion to a wide variety of substrates, including PP, PE, ABS, PC, PCTG, PA, and glass-reinforced PA. This versatility makes it an ideal choice for significantly enhancing product ergonomics, durability, and user experience across diverse industries.
Key Advantage: Strong, permanent adhesion to PP, PE, ABS, PC, PCTG, PA, and glass-reinforced PA substrates with customized formulations.
It is extensively used to create comfortable, non-slip surfaces on toothbrush handles, tool grips, and larger items like folding buckets and bathtubs. In consumer electronics and power tools, such as Bluetooth speakers and drill handles, it provides a secure grip that improves safety and handling while protecting the core structure from impacts. The material's reliable processability in injection molding and its consistent performance make it a preferred and trusted solution for meeting both functional and aesthetic demands in numerous consumer and industrial applications.
