Overmolding Techniques & Adhesion Requirements

SILIKE Si-TPVs Overmolding can adhere to other materials through injection molding. suitable for insert molding and or multiple material molding. Multiple material molding is otherwise known as Multi-shot injection molding, Two-Shot Molding, or 2K molding.

SI-TPVs have excellent adhesion to a variety of thermoplastics, from polypropylene and polyethylene to all kinds of engineering plastics.

When selecting an Si-TPV for an over-molding application, the substrate type should be considered. Not all Si-TPVs will bond to all types of substrates.

Application

Si-TPVs provide a uniquely smooth feel in hardness ranging from Shore A 35 to 90A making them the ideal material to enhance the aesthetics, comfort, and fit of 3C Electronic Products, including hand-held electronics, wearable devices(from phone cases, wristbands, brackets, watch bands, earbuds, necklaces, and AR/VR to silky-smooth parts…), as well as improve scratch resistance and abrasion resistance for the housings, buttons, battery covers and accessory cases of portable devices, consumer electronics, household products, and homewares or other appliances.

Si-TPV offers an exquisitely soft touch feel that surpasses traditional materials. The touch sensation is akin to high-quality silicone rubber, providing an inviting and comfortable user experience.While Si-TPV feels soft and silky, it also exhibits excellent durability. It resists wear and tear, making it ideal for applications on frequently handled devices. Si-TPV ‘s resilience ensures the longevity of the soft touch feel.

Moreover, Si-TPV is recyclable and environmentally friendly, aligning with the increasing emphasis on sustainable manufacturing practices.

Si-TPV will emerge as an innovative solution for soft touch overmolding, to enhance the aesthetics, comfort, and fit of 3C Electronic Products, including hand-held electronics, wearable devices(from phone cases, wristbands, brackets, watch bands, earbuds, necklaces, and AR/VR to silky-smooth parts…), as well as improve scratch resistance and abrasion resistance for the housings, buttons, battery covers and accessory cases of portable devices, consumer electronics, household products, and homewares or other appliances.

Si-TPV, short for Thermoplastic Silicone Vulcanizate, is a remarkable material that has revolutionized headphone design. It combines the advantages of thermoplastics and silicone rubber, resulting in a versatile material that offers the best of both worlds. When Headphone manufacturers adopt Si-TPV in their designs, will reap the benefits:
1. Incorporated Si-TPV into its headphone cushions, providing users with a comfortable and stylish listening experience. The soft-touch feel of Si-TPV complements the brand's commitment to both aesthetics and performance. 2. Si-TPV material's durability ensures headphones maintain their sleek appearance even after years of use. 3. Si-TPV enhances the comfort and aesthetics of their renowned noise-canceling headphones. Users can enjoy superior audio quality without sacrificing style and comfort!
