Description LYPA-208C is a special silicone polymer dispersed in LDPE, It is widely used as an efficient lubricant in XLPE cable compounds . When the dosage at 0.1 to 1.0%, it can improve the processing properties including better mold release, reduced extrusion torque , less die drool ; at a higher loading at 1-5%, It can enhance surface quality such as more slip, lower COF, improve abrasion resistanc....etc Benefits 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 poor processing, and the compounds are easily adhere to the screw groove and mold dead corners and form 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 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.
