Description

Silicone Masterbatch ( Siloxane Masterbatch ) LYSI-406 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 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 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.cnMore and more headset lines and data lines are made by TPE compound, the main formula of it are SEBS, PP, fillers, white oil, and granulate with some other additives. Silicone has played a very important role in it. Due to the payout speed of the TPE wire being very fast, usually, about 100 – 300 m/s, and the diameter of the wire being very small, so a very big shear force which is vertical to wire direction will form at the dies and is easily caused melt fracture. That’s why silicone masterbatch must be added to improve the flow of resin. At the same time, headset lines and data lines makers must be noted that the effect is significantly different between the good and bad quality silicone masterbatch, a good one will leading a very nice dry surface finish of wire; a bad one might offer a certain surface smooth also, but with sticky.

At present, Apple, Samsungs headphone line and data lines must use Dowcorning, wacker, or SILIKE silicone masterbatch products LYSI-406
