Description

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

Fundamental Parameters

Benefits

(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) XLPE cable compounds

(3) Telecommunication pipe , HDPE microduct

(4) PE plastic film

(5) TPE/TPV compounds

(6) Other PE 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 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.

In wire & cable compounds, especially for halogen-free flame retardant (HFFR), Low smoke zero halogen (LSZH) wire and cable compounds, their dosage is so high (55-70%) that the flowability and processing ability of resin is quite poor, dispersion of flame retardancy will be a big issue, and the appearance of extruded wire & cable will have some defects.

After silicone masterbatch is added to the system, flowability, processing of resin, and dispersion property of flame retardancy will be improved apparently. The extrusion line speed, scratch resistance, and wear resistance of wire and cable will be highly improved.
