Wood-Plastic Composites - an overview | ScienceDirect Topics

Typical wood plastic composites or wood plastic compounds (WPC) are made out of 40–70% predried wood flour, 25–55% PE (high-density polyethylene, low-density polyethylene), PP, or PVC, and 5% additives such as lubricants, pigments, stabilizers, coupling agents, biocides, processing aids, bonding agents, FR additives, and UV-protective additives.
