ALFATER XL® ECO A75I 2GP0001 BK0002-00

What is it?

This is a thermoplastic vulcanizate elastomer based on 40-45% polypropylene recyclate and partly-biobased (70%) EPDM. It offers an economical and sustainable alternative to conventional fossil-based TPV (PP+EPDM) for applications that need flexibility. The used rPP is Post Industrial Recyclate (PIR) sourced from local certified suppliers.
The EPDM is made from bio-ethylene derived from sugar cane.

Technical benefits

The properties of the material are very similar to conventional fossil-based TPV.

It is available in different Shore hardnesses – Shore A75, D40, D50 (other hardness possible on request). Services a broad temperature range, from -40 °C up to 130 °C, depending on load. It shows resistance against weathering, moisture, UV, ozone, many aqueous solutions, acids, and alkaline solutions. It is resistant to heat ageing and bonds to polyolefins in over-moulding applications.

Look and feel

The sample represents a relatively soft grade, Shore A 75. The EDM surfaces of the mould are repeated nicely and the polished surfaces have a silky appearance. The material provides a very nice touch that can be used in applications where a good grip is needed.

Environmental benefits

The material can be used as a drop-in solution replacing fossil-based TPV. Because of the use of recycled plastic and the reduced use of oil, the CO2-saving potential of a combination of rPP and bio-EPDM can be up to 60%. The material can also be recycled in closed-loops.

Applications

Because of its chemical resistance and mechanical performance, the material is well suited for technical applications that benefit from softness and flexibility, such as mudguards, dust covers, sealings and gaskets, casters, toppers and plugs, protectors, handles, and grips. In addition to injection moulding, this grade is also suitable for extrusion.

Why we chose this material 

TPV is one of the most commonly used thermoplastic elastomers. This grade, being partly bio-based and partly recycled, offers a good alternative to virgin grades with a substantially reduced carbon footprint.

Why you should consider this material

  • You want an injection-mouldable flexible thermoplastic suitable for over-moulding on polyolefins (recycled or virgin) or TPE (recycled or virgin).

  • You don’t want to use pure rubber, which is a thermoset material and therefore difficult to recycle. 

  • You want to find a more sustainable alternative to conventional TPV without compromising the performance of your product.
