TP-36-EVA Foam Modification Agent

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.

Key Features

Enhances elasticity and rebound performance of EVA materials
Improves toughness and crack resistance
Reduces shrinkage during molding and foaming processes
Enhances dimensional stability and molding precision
Improves foam uniformity and structure consistency
Excellent compatibility and processing stability
Extends product durability and service life

Recommended Addition Level

Recommended loading level: 1–5 wt%
The optimal addition ratio may vary depending on the base resin, performance requirements, and product design.

Recommended Processing Methods

TP-36 can be directly incorporated into EVA foaming formulations based on product requirements. The dosage can be adjusted according to shrinkage control targets, anti-slip performance requirements, and cost optimization strategies.

It is fully compatible with existing EVA foaming production processes and does not require additional equipment modification, enabling fast and efficient industrial-scale implementation.
