Polyolefin Thermoplastic Elastomer-TPO

TPO materials are defined as compounds of various polyolefin polymers, semi-crystalline thermoplastics,
and amorphous elastomers. The most common types of TPOs are composed of polypropylene
and ethylene-propylene rubber (EPR). EPR may be a copolymer of either only ethylene and propylene
monomers or a third monomer. The diene monomer provides a small amount of unsaturation in the polymer chain for sulfur cross-linking. This is called EPDM rubber
