RAW MATERIALS AND APPLICATIONS Organotin-free Catalysts for Silane Curing Polyolefin Elastomer/Linear low Density Polyethylene Blends via reactive Extrusion

A compound of crosslinking polyolefin elastomer (POE)/ linear low-density polyethylene (LLDPE) blend, as a class of thermoplastic elastomer family, was prepared through a two-step silane grafting method (Sioplas process) using twin-screw extruder. The silane grafted compound was used as wire and cable coatings. 

Thermoplastic elastomers (TPEs) exhibit elastomeric behavior along with the melt process ability of thermoplastics. This dual behavior of TPEs has opened a new field in polymer science [1 to 6]. POEs family has a significant role in growing the TPEs markets. The use of POEs in various industries is widely adopted due to the extensive variety of their products, easy production method and desirable price/performance relationship. Polyolefin thermoplastic compounds based on blends of semicrystalline polyolefin and polyolefin elastomers have become more popular [7 to 9].
