Click thermal cross linked polypropylene
WebProperties. Polyolefins, also called polyalkenes, are the largest class of commodity thermoplastics. They are polymers of simple alkenes such as ethylene, propylene, butenes, and pentenes, and copolymers thereof. The two most important polyolefins are polyethylene (PE) and polypropylene (PP). They can be processed by common forming techniques ...
