Description

Silicone Masterbatch ( Siloxane Masterbatch ) LYSI-408 is a pelletized formulation with 30% ultra high molecular weight siloxane polymer dispersed in polyester (PET ). It is widely used as an efficient processing additive in PE 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 additives, 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) PET fibers

(2) PET & BOPET film

(3) PET bottle

(4) Automotive

(5) Engineering plastics

(6) Other PET 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 . For better result , pre-drying is recommended for 3~4 hours at 120℃.

Recommend dosage

When added to PET 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

Package

25Kg / bag , craft paper bag

Storage

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.
