Less Extruder Torque with Silicone Masterbatch LYSI 402
in EVA
Product Brief Introduction
Silicone Masterbatch ( Siloxane Masterbatch ) LYSI-402 is a pelletized formulation with 50% ultra high molecular weight siloxane polymer dispersed in ethylene-vinyl acetate copolymer (EVA ). It is widely used as an efficient additive in EVA compatible resin system to improve the processing properties and modify surface quality.
Compare to conventional lower molecular weight Silicone / Siloxane additives,like Silicone oil, silicone fluids or other type processing aids, SILIKE Silicone Masterbatch LYSI series are expected to give improved benefits, eg,. Less screw slippage , improved mold release, reduce die drool, a lower coefficient of friction, fewer paint and printing problems, and a broader range of performance capabilities.

Benefits
(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
Applications
(1) HFFR / LSZH cable compounds
(2) EVA footwear
(3) Foamed EVA products
(4) Thermoplastic elastomers
(5) Other EVA compatible systems
How to use
SILIKE LYSI series silicone masterbatch may be processed in the same way as the resin carrier on which they based. It can be used in classical melt blending process like Single /Twin screw extruder, injection molding. A physical blend with virgin polymer pellets is recommended .
Recommend dosage
When added to EVA 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
