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.

Silicone based thermoplastic elastomers are used as soft elastomers and soft overmolding materials in applications such as baby tableware, bedside rails, stroller handles, toys, teethers, baby food bibs and more. In addition, it can also be used as a Soft EVA foam modifier to create foam baby toys and related products.

3. Thermoplastic Elastomers (TPEs): Soft and Flexible
Thermoplastic elastomers (TPEs) are versatile materials with excellent softness and flexibility. They are used in baby bottle nipples, pacifiers, and baby toys. TPEs are gentle on sensitive gums and provide a comfortable experience for infants.
4. Dynamic vulcanizate thermoplastic Silicone-based elastomers (Si-TPVs): Long-term silky skin-friendly touch
This series is an environmentally friendly alternative to PVC and silicone or traditional plastics, it is silicone combined with TPU to get Modified silicone elastomers, enabling manufacturers to create unique products that are visually appealing, aesthetically pleasing, comfortable, ergonomic, and colorful because the surface is non-migratory, non-adhesive, and more resistant to germs, dust, and stains than any other material.
