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 .

Silicone powder ( Siloxane powder ) S201 is a powder formulation which contains 55% UHMW Siloxane polymer dispersed in Silica . It is particularly developed for Polyolefin masterbatches/ filler masterbatches to improve the dispersion property by better infiltrate in fillers. 

Compare to conventional lower molecular weight Silicone / Siloxane additives, like Silicone oil, silicone fluids or other type processing aids, SILIKE Silicone powder S201 is expected to give improved benefits on processing properties and modify the surface quality of final products, eg,. Less screw slippage , improved mold release, reduce die drool,  lower coefficient of friction, fewer paint and printing problems, and a broader range of performance capabilities.

How to use

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.

Recommend dosage

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


20Kg / bag , craft paper bag


Transport as non-hazardous chemical. Store in a cool , well ventilated place .

Shelf life

Original characteristics remain intact for 24 months from the production date , if kept in recommend storage.
