S201 is a powder formulation which contains 55% UHMW Siloxane polymer dispersed in Silica . It is particularly developed for Polyolefin masterbatches to improve the dispersion property by better infiltrate in fillers . Compare with those traditional external additives like Amide , Wax , Ester etc , it’s more efficient without any migration problem.

(1)Improve processing properties including better flow ability , reduced extrusion die drool , less extruder torque , better molding filling & release
(2) Improve surface quality like surface slip, lower Coefficient of friction
(3) Greater abrasion & scratch resistance
(4) Faster throughput , reduce product defect rate.
(5) Enhance stability compare with traditional processing aid or lubricants
(1) Color masterbatches
(2) Filler masterbatches
(3) Engineering plastics
(4) Wire&cable compounds
(5) PVC compounds

SILIKE silicone powder can be used in classical melt blending process like Single /Twin screw extruder, injection molding. A physical blend with virgin polymer pellets is recommended . For better test result, Strongly suggest to pre-blend Silicone powder and thermoplastic pellets prior to introduction to extrusion process.
When added to polyethylene or similar thermoplastic at 0.2 to 1% , improved processing and flow of the resin is expected, including better mold filling, less extruder torque, internal lubricants, mold release and faster throughput; At a higher addition level , 2~5%, improved surface properties are expected, including lubricity , slip, lower coefficient of friction and greater mar/scratch and abrasion resistance.
