Silicone Masterbatch for Improved Processing of LSZH/HFFR Wire & Cable Compounds | LYSI-401

Silicone Masterbatch (Siloxane Masterbatch) LYSI-401 is a silicone-based additive containing 50% ultra-high molecular weight siloxane polymer dispersed in a polyethylene (PE) carrier. Designed as an effective processing and surface-modification additive for PE-compatible compounds, particularly highly filled wire and cable formulations, it helps reduce processing resistance, improve melt flow and extrusion stability, and enhance surface quality. Silicone Masterbatch LYSI-401 can support more efficient processing while maintaining the mechanical performance of the finished compound.

Description

Silicone Masterbatch ( Siloxane Masterbatch ) LYSI-401 is a pelletized formulation with 50% ultra high molecular weight siloxane polymer dispersed in polyethylene (PE ). 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 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.

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 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

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.
