TP-36 | EVA Foam Modification Agent

TP-36 is a high-performance modification agent specifically designed for Ethylene-Vinyl Acetate (EVA) materials. It is developed to enhance elasticity and flexibility, improve toughness, and significantly reduce shrinkage issues during processing and foaming.
Through advanced elastomer modification technology, TP-36 improves rebound resilience and durability of EVA materials while enhancing dimensional stability. It effectively minimizes deformation, warpage, and dimensional deviation caused by shrinkage, resulting in superior product appearance and consistent molding quality.
