Wood–plastic composite (WPC) is a composite material made of plastic as a matrix and wood as filler, the most critical areas of additive selection for WPCs are coupling agents, lubricants, and colorants, with chemical foaming agents and biocides not far behind.
Usually, WPCs can use standard lubricants for polyolefins and PVC, such as ethylene bis-stearamide , zinc stearate, paraffin waxes, and oxidized PE.
Why are lubricants used?
Lubricants are used in the production of wood plastic composites to improve processing and increase output. The extrusion of wood plastic composite materials can be slow and energy-consuming due to the dry nature of the material. This can lead to inefficient processes, a waste of energy, and increased wear on machinery.
SILIKE SILIMER 5332 as a novel processing lubricant, brings innovative power to convince your WPCs. suitable for HDPE, PP, PVC, and other wood plastic composites, widely applicated in homes, construction, decoration, automotive, and transportation fields.
SILIKE SILIMER 5332 can be incorporated directly into composite materials during extrusion, allowing the following benefits to be seen:
1) Improve processing, reduce extruder torque;
2) Reduce internal and external friction, reduce energy consumption and increase production capacity;
3) Has 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) Improve hydrophobic properties, reduce water absorption;
5) No blooming, long-term smoothness;
6)Superior surface finish…
