LYSI-409 is a pelletized formulation with 50% ultra high molecular weight siloxane polymer dispersed in thermoplastic urethanes ( TPU ). It is widely used as an efficient additive for TPU compatible resin system to improve the processing properties and surface quality, such as better resin flow ability , mold filling & release, less extruder torque , lower coefficient of friction , greater mar and abrasion resistance .

(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

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 .
When added to TPU 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.
