Thermoplastic Vulcanisates (TPV) materials are typically used in applications requiring improved heat or fluid resistance.

TPVs are compounds of PP and EPDM rubber which have been dynamically vulcanised during the compounding process.

The vulcanisation process changes the structure of the rubber, making it more durable, improving its recovery to deformation and making it more resistant to the ingress of aggressive fluids such as oils and solvents.
 
➜ The new biobased TPV materials will expand on the Dryflex Green TPE range, which already includes TPS and TPO materials. Dryflex Green TPEs contain a percentage of raw materials from renewable resources such as plant and vegetable crops.
 
➜ The Biobased TPV materials are available in hardnesses 65 to 85 Shore A with amounts of biobased content up to around 25% (ASTM D 6866).
 
➜ For the new TPV grades with recycled content, the recyclate source is PCR (Post Consumer Recyclate), including recycled PP from end-of-life vehicles. Other sources include household plastic waste.

➜ TPVs are available with amounts of recycled content up to 28%. Heat ageing, oil resistance and viscosity tests have been done. They offer a broad service temperature range from -50 to +135 °C
 
➜ The biobased and circular TPV materials can be processed on standard thermoplastic equipment, such as injection moulding and extrusion. They also offer superior bonding to polyolefins in multi-component processing. They can be recycled in closed-loop systems.
