Some polymer grades on the plastic market are already manufactured using renewable sources such as corn, sugar cane, and vegetable oil.
The bio-based content of the polymer can be between 70% and 100% depending on the polymer grade.

Avient’s team recommended the use of overmolding (two-shot injection molding) to integrate the boot with the saw housing, and trialed several products before customizing a grade from its portfolio.
The TPE grade surpassed the performance of the previous material and allowed the manufacturer to introduce a more efficient production process.

Next, the materials team formulated a grade that would offer
enough heat resistance to be overmolded onto polypropylene,
the underlying rigid material.
Finally, the OnFlex-S HF grade
was developed to bond sufficiently and be chemically
compatible with polypropylene.
Natural
grades can be colored during processing with compatible
products from Avient’s OnColor™ color concentrate line

VALUE
ECCOH LSFOH grades can run at high processing
speeds of up to 1,000 m/min and, with a much
lower melting temperature than PBT alternatives,
can greatly enhance manufacturing efficiency.
RHEOLOGICAL PERFORMANCE
ECCOH 6153/6154 UV grades offer enhanced rheological pbehavior.
Performing at a lower pressure and with
less stress enables a smoother surface finish and can increase processing speeds by up to 15% compared to
alternative grades.
