Description

Silicone Masterbatch ( Siloxane Masterbatch ) LYSI-506 is a pelletized formulation with 50% ultra high molecular weight siloxane polymer dispersed in Polypropylene  (PP ). 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.

Fundamental Parameters

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.

(3)  lower Coefficient of friction.

(4)  Greater abrasion & scratch resistance

(5) Faster throughput , reduce product defect rate.

(6) Enhance stability compare with traditional processing aid or lubricants

Applications

(1) Thermoplastic elastomers

(2) Wire&Cable compounds

(3) BOPP,CPP film

(4) PP Funiture / Chair

(5) Engineering plastics

(6) Other PP compatible plastics

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 PP 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.

Chengdu Silike Technology Co., Ltd is a manufacturer and supplier of silicone material, who has dedicated to R&D of the combination of Silicone with thermoplastics for 20⁺ years, products including but not limited to Silicone masterbatch , Silicone powder, Anti-scratch masterbatch, Super-slip Masterbatch, Anti-abrasion masterbatch, Anti-Squeaking masterbatch, Silicone wax and Silicone-Thermoplastic Vulcanizate(Si-TPV), for more details and test data, please feel free to contact Ms.Amy Wang  Email: amy.wang@silike.cnTPU and EVA resin are very sticky with poor anti-blocking property, particularly for those thin film are easier to face this problem. at present , the main solution is use amide with inorganic anti-blocking agent, although the anti-blocking and smooth will be improved but still with migration problem.our super-slip masterbatches can effectively solve this problem and offer better smooth and anti-blocking property , but it will affect on transparency. However, Due to the refractive index of silicone is different with most resin, so even a small dosage of silicone will affect the transparency of film. but we can reduce the affect by adjust the thickness of film.Take cigarette film as example, we only use silicone in it’s top layer which is just 2-3 micron, so almost no affect on transparency. Dosage:2-3%
