What is TPV?

TPV is a type of thermoplastic elastomer made by dynamically vulcanizing rubber (typically EPDM) within a thermoplastic matrix like polypropylene (PP). This process blends the elasticity of rubber with the processability of plastic.

Key Properties

• Elasticity: Returns to its original shape after stretching or compression.
• Chemical Resistance: Withstands oils, acids, and bases.
• Weather Resistance: Performs well in fluctuating temperatures and outdoor conditions.
• Durability: Long service life with good wear resistance.
• Processability: Can be molded using standard thermoplastic techniques like injection molding and extrusion.
• Recyclability: Scrap material can often be reprocessed.

Advantages

• Combines rubber-like flexibility with plastic-like ease of processing.
• Reduces production time compared to traditional thermoset rubbers.
• Suitable for a wide range of applications: automotive seals, consumer goods, medical components, and construction materials.
• Lightweight and fuel-efficient in automotive use.
• Broad temperature range (-60°C to 135°C) and hardness options.

Disadvantages

• Generally more expensive than simpler TPEs.
• It may not match the extreme performance of fully cured rubbers in high-stress environments.

Requires careful formulation and processing to achieve optimal properties.

Applications
