Finally, the new TPE grades also boasted lower extractables because they required no crosslinking, unlike thermoset silicones. Reduced freight costs: The lower specific gravity of TPEs versus thermoset silicone rubber cut the overall part weight by 20 percent. Reduced scrap costs: The easy processability of  the two TPE materials resulted in major scrap rate reductions totaling more than $70,000 a year.

Minimize the thickness of the soft TPE Use a lower hardness for the TPE Prevent the TPE from flashing over areas on the substrate.
