China Lubricant additive (processing aids) for WPC SILIMER 5322 Manufacture and Factory

Lubricant additive (processing aids) for WPC SILIMER 5322

This product is a lubricant solution for WPC specially developed for wood composites manufacturing of PE and PP WPC (wood plastic materials). The core component of this product is modified polysiloxane, containing polar active groups, excellent compatibility with resin and wood powder, in the process of processing and production can improve the dispersion of wood powder, does not affect the compatibility effect of compatibilizers in the system, can effectively improve the mechanical properties of the product. This WPC additive is cost-effective, excellent lubrication effect, can improve the matrix resin processing properties, but also can make the product smoother. Better than WPC wax or WPC stearate additives.

Advantages of WPC lubricant additives

1. Improve processing, reduce extruder torque, improve filler dispersion;

2. Reduce internal and external friction, reduce energy consumption and increase production efficiency;

3. Good compatibility with wood powder, does not affect the forces between the molecules of the wood plastic composite and maintains the mechanical properties of the substrate itself;

4. Reduce amount of compatibilizer, reduce product defects, improve appearance of wood plastic products;

5. No precipitation after boiling test, keep long-term smoothness.

How to use

Addition levels between 1~5% are suggested. It can be used in classical melt blending process like Single /Twin screw extruders, injection molding and side feed. A physical blend with virgin polymer pellets is recommended.

Transportation & Storage

This WPC processing additive could be transported as non-hazardous chemical. It is recommended to be stored in a dry and cool area with a storage temperature below 40 ° C to avoid agglomeration. The package must be well sealed after each use to prevent the product from being affected by moisture.

Package & Shelf life

The standard packaging is a craft paper bag with PE inner bag with net weight of 25kg. Original characteristics remain intact for 24 months from the production date if kept in recommend storage.
