SILICONE MASTERBATCH LYPA-208C

Silicone Masterbatch ( Siloxane Masterbatch ) LYPA-208C is a pelletized formulation with 50%   ultra-high molecular weight silicone polymer with a special chemical structure dispersed in LDPE,  It could be used as a particular processing additive in XLPE compounds 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, It is 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. What’s more, it could prevent undesired pre-crosslinking but without influence on final cross link speed and rate.

Features

The linear structure of LLDPE will turn into a three-dimensional cross-linking network after Silane-grafting and cross-linking reaction, in this way poor flow of resin result in poor processing, and the compounds are easily adhered to the screw groove and mold dead corners and form a dead mass which will affect the extruded cable appearance ( rough surface with little pre-crosslinking particles which formed at cross-linking step ), so effective lubricant like LYPA-208C added to improve the processing and modify the extruded surface.

How to use

Addition levels between 0.2~5.0% is suggested . It can be used in classical melt blending process like Single /Twin screw extruders, injection molding. A physical blend with virgin polymer pellets is recommended . For better result , pre-drying is recommend for 1 hour at 70-75 ℃ .

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.
