Si-TPV 3100-55A Elastomer| Skin-Friendly Silicone Additive & Modifier for TPU & TPE with Abrasion Resistance and Soft Touch
describe:
SILIKE Si-TPV thermoplastic elastomer is a dynamic vulcanized thermoplastic silicone-based elastomer which made by a special compatible technology to help silicone rubber dispersed in TPU evenly as a 2~3 micron particles under microscope. Those unique materials combine the strength, toughness and abrasion resistance of any thermoplastic elastomer with desirable properties of silicone: softness, silky feel, UV light and chemicals resistance which can be recycled and reused in traditional manufacturing processes.

Applications
Si-TPV 3100-55A is not only a versatile raw material but also features an innovative silicone-based modifier and additive. This combination provides a long-lasting, skin-friendly soft touch and excellent stain resistance. Free from plasticizers and softeners, it ensures safety and performance without any precipitation, even after extended use. This series serves as an effective plastic additive and polymer modifier, making it ideal for enhancing thermoplastic polyurethane (TPU) or thermoplastic elastomer (TPE) formulations.
Si-TPV not only imparts a silky, pleasant feel but also reduces TPU hardness, achieving an optimal balance of comfort and functionality. It provides a matte finish, along with durability and abrasion resistance, making it an ideal solution for various applications, including consumer goods, automotive parts, EV charging cables, medical devices, water pipes, hoses, and sports equipment—where comfort, durability, and aesthetic appeal are essential.
Unlike conventional silicone additives, Si-TPV is supplied in pellet form and processes like a thermoplastic. It disperses finely and homogeneously throughout the polymer matrix, with the copolymer physically bound, preventing migration or "blooming." This makes Si-TPV a reliable and innovative solution for achieving silky-soft surfaces in thermoplastic elastomers or other polymers, without the need for additional processing or coatings.
