China Wholesale Dimethylpolysiloxane Factory – silimer tm 5050 – Silike Detail:

Description

SILIMER 5050 is a long-chain polar functional group alkyl modified silicone additive with excellent thermal stability. It is used in thermoplastic products such as PE, PP, PVC, PBT, PET, ABS, PC, etc. It could Obviously improves the scratch-resistant and wear-resistant surface properties of products, improves the lubricity and mold release of the material during processing process, largely decreases the Coefficient of dynamic and static friction to make the surface of products more smooth. At the same time, SILIMER 5050 has a special structure with good compatibility with the matrix resin, no precipitation, no effect on the appearance and surface treatment of products.
