New technology silane crosslinked wire & cable compound,
,

Description

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.

Fundamental Parameters

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.

 Silane grafing reaction occured during the process of silane crosslinked wire & cable compounds, at the same time some crosslinking reaction occured. If lubricancy for resin is no good, resin will be easily adhere to the cylinder wall, die angle, forming deposition, thus When LYPA-208C is added at dosage from 0. 3% to 2.0%, the flow ability of resin will be faster, cleaning cycle for equipment will be extended, the appearance of products will be better. And the platicizing and mechanical properties will be improved.
