HAMBURG, Germany—German compounder Mocom Compounds GmbH & Co. has developed a thermoplastic vulcanizate elastomer (TPV), produced from recycled PP (rPP) as well as, on request, partly bio-based raw materials such as bio-EPDM.
For the range, labelled Alfater XL ECO, the rPP is based on post-industrial-recyclate (PIR), whereas the partly bio-based EPDM has a bio-content of 70 percent.
According to Mocom, the rPP and bio-based content of the TPV depends on its hardness.
The rPP content for hard Alfater XL ECO grades, like Shore D50, for example, can be more than 80 percent, while in soft TPV the bio-based content is respectively high.
“With this mix of raw materials, the production of sustainable TPV materials with different levels of CO2 saving potentials is possible,” the company said.
