TPV Series | Weather-Resistant Thermoplastic Vulcanizates (TPV)

Product Overview

The TPV Series consists of high-performance Thermoplastic Vulcanizates (TPV) manufactured through dynamic vulcanization technology, where crosslinked rubber particles are finely dispersed within a thermoplastic polyolefin matrix. This unique structure combines the elasticity of conventional rubber with the processing advantages of thermoplastics.
Designed for demanding environments, the TPV Series offers outstanding weather resistance, heat aging resistance, ozone resistance, and chemical resistance, ensuring long-term durability under harsh outdoor and high-temperature conditions.
Compared with conventional SEBS-based TPEs, the TPV Series provides significantly improved heat resistance, weatherability, and compression set performance, making it an ideal material solution for automotive components, building sealing systems, household appliances, and industrial equipment.

Key Features

✔

Excellent Weather Resistance
Outstanding resistance to UV exposure, ozone, and environmental aging ensures reliable long-term outdoor performance.

✔

Superior Heat Aging Resistance
Maintains excellent elasticity and mechanical properties under prolonged elevated-temperature conditions.

✔

Low Compression Set
Provides excellent elastic recovery after long-term compression, improving sealing performance and extending product service life.

✔

Excellent Chemical Resistance
Resistant to a wide range of acids, alkalis, detergents, and common industrial chemicals for enhanced durability.

✔

Lightweight Material Design
Lower density than conventional EPDM rubber helps reduce component weight while maintaining excellent mechanical performance.
