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.

Si-TPV Modified silicone elastomer/Soft elastic material/soft overmolded material is an innovative approach for manufacturers of smart watch bands and bracelets that require unique ergonomic designs as well as safety and durability. It is an innovative approach for manufacturers of smart bands and bracelets that require unique ergonomic design as well as safety and durability. In addition, it is also widely used as a replacement for TPU coated webbing, TPU belts and other applications.
Key Benefits of Si-TPV Silicone Elastomer for Watch Bands:
✅Optimized Durability: Si-TPV addresses the common weakness of traditional silicone gel materials by offering enhanced resistance to vacuuming, aging, and breakage, ensuring long-lasting durability.
✅Superior Soft Touch Feel: The surface of Si-TPV boasts a unique silky and skin-friendly touch, providing unparalleled comfort for wearers.
