Known for offering tight seals and reducing
vibration and noise, certain thermoplastic elastomers
(TPEs), like OnFlex™ grades, may be better suited
for your particular application than the historically
incumbent materials, like general purpose TPEs,
thermoplastic vulcanizates (TPV), and thermoplastic
polyolefins (TPO).

A Beginner’s
Guide to TPE
There’s a lot of information swirling around the internet about thermoplastic
elastomers (TPEs) and similar materials such as TPU, TPV, and silicone.
You may hear people talk about TPVs
(thermoplastic vulcanizates) or TPUs (thermoplastic polyurethane) instead of
TPEs.
In reality, TPVs and TPUs are both types of TPEs, and are two of the most
common.
https://www.avient.com/news/lighter-weight-easier-processing-heat-resistance-polyone’s-crosslinkable-barricade-elastomers-have-it-all
Based on Fortrex™ technology licensed from Cooper Standard, this crosslinkable elastomer offers high-temperature compression set performance, easier processing, and a lighter weight solution when compared to conventional TPVs, silicones, and thermoset rubbers.
Barricade solutions are lighter in weight and show improved tear strength over general-purpose TPV and silicone materials.

As an example, in order to
bond to engineering thermoplastic, the continuous phase in a TPV has to be modified significantly.
Most Dynaflex® (Styrenic
block copolymer TPE), Versaflex® (polar modified alloys) and Versalloy® (TPV alloy compounds are suitable
for two-shot or insert molding with a polypropylene (PP).
TPEs in
Table 4 are styrenic materials where as TPVs are the dynamic vulcanizates of polypropylene and EPDM.
