Description

WPL 20 is a solid pellet contain UHMW Silicone copolymer dispersed in HDPE , it is particularly designed for Wood plastic composites . Small dosage of it can significantly 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, SILIKE Additive Masterbatch WPL 20 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.

Including reduce the COF , lower extruder torque , higher the extrusion-line speed, durable scratch & abrasion resistance and excellent surface finish with good hand feel . Suitable for HDPE , PP, PVC .. wood plastic composites .

Benefits

1. With both internal and external lubricant effects , improve the surface quality

2. Better processing ability

3. Improve wood powder dispersion property 

4. Minimized addition level , cost saving .

5. Reduce extruder torque ,  higher extrusion -line speed ( Higher output )

6. No negative affect on Mechanical properties

How to use

Mix WPL20 , Plastic and Wood powder at a certain ratio.  It can be used in classical melt blending process like Twin screw extruders, injection molding. A physical blend with neat polymer compounds is recommended .

Recommend dosage

When added to polyethylene 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 , 1~3%, 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 with a PE inner bag 

StoragePackage & Storage

Transport as non-hazardous chemical. Store in a cool , well ventilated place .

Original characteristics remain intact for 12 months from the production date , if kept in recommend storage.
