TPSiV™ Multiflex®SiE is a cutting-edge silicone-enhanced thermoplastic elastomer (TPE) developed by Avient Corporation, designed to offer the premium touch, flexibility, and resilience of silicone rubber with the processing efficiency and recyclability of thermoplastics. As a member of the Thermoplastic Silicone Vulcanizate (TPSiV™) family, it features a co-continuous blend of cured silicone particles within a thermoplastic matrix, resulting in a material that is soft, durable, and resistant to wear.

This unique composition gives TPSiV™ Multiflex®SiE its signature silky, non-tacky surface, excellent UV and chemical resistance, and long-term skin compatibility, making it ideal for products requiring direct contact with the body or demanding environmental exposure. The material is fully processable using injection molding, extrusion, and overmolding techniques—no vulcanization or post-curing needed—making it a cost- and energy-efficient solution for modern manufacturing.
