has added to their growing portfolio of resource-saving materials with the addition of biobased TPV and TPV containing recycled content.
Reduce Fossil Resources Use
The new bio-based TPV materials will expand 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. They help to decrease the use of virgin fossil resources.
The Dryflex® Green TPV materials are available in hardnesses 65 to 85 Shore A with amounts of biobased content up to around 25% (ASTM D 6866).Related Read: Thermoplastic Elastomers 101: An Ultimate Guide.?
PCR from End-of-Life Vehicles
The company has also added new TPV grades to their Dryflex® Circular range of materials 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.
Dryflex® Circular TPVs are available with amounts of recycled content up to 28% (as defined in ISO 15343 section 4). Heat ageing, oil resistance and viscosity tests have been carried out. Dryflex® Circular TPVs 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 molding and extrusion. They also offer superior bonding to polyolefins in multi-component processing. They can be recycled in closed-loop systems.“I’m pleased to present our new TPV materials, adding to our growing portfolio of bio-based and circular products
