Wood-Plastics Composites Done Right | Plastics Technology
PVC, polyethylene, and polypropylene are the most commonly used plastics in WPC extrusion. PVC is suited to counter-rotating extruders with low (
Wood Plastic Composite & WPC Building Materials | Dow Inc.
Our silicone enhanced polymer system (SEPS) – AMPLIFY Si PE 1000 Polymer System – allows even higher levels of recycled plastic and wood content while maintaining or improving WPC performance. In addition to putting less plastic and wood into landfills, WPCs made with AMPLIFY Si materials can help reduce energy costs and carbon
The Best Composite Decking - The Spruce
Cali-Bamboo also sells fencing, plywood, poles, edging, flooring, and paneling products for decking projects. Its BamDeck composite is made from 60 percent recycled bamboo fibers and 40 percent recycled plastics. The TruOrganics product line is made of 100 percent recycled wood fibers. Cali-Bamboo products cost about $15 to $75, depending on
Choosing the Best Composite Decking - Building Advisor
Special screws designed for composite decking leave a clean hole without dimpling around the screw head. Most solid products cannot exceed 16-inch on-center framing, and they feel a little bouncy underfoot due to the material’s greater flexibility (low modulus of elasticity) compared to wood.

- How do you choose a WPC additive?
- The most critical areas of additive selection for WPCs are coupling agents, lubricants, and colorants, with chemical foaming agents and biocides not far behind. Selection of specific types for WPCs depends on the base resin. Polyethylene-based wood composites—mainly recycled HDPE—account for 80% of the market.
- What lubricants are available for foamed WPC composites?
- Reedy International, supplier of Safoam endothermic chemical foaming agents, is offering three new lubricants for foamed WPC composites. Safoam WSD is a lubricant and antioxidant that is applied to the wood flour. It is designed for PP and PVC containing up to 70% wood.
- What is the percentage of polyethylene based wood composites?
- Polyethylene-based wood composites—mainly recycled HDPE—account for 80% of the market. Wood-PVC is 10% to 13% and wood-polypropylene, 8%. Wood-polystyrene accounts for only 1% to 2%. Coupling agents bond the wood fiber to the resin matrix.
- Which CFA is best for wood-polyolefin & PVC composites?
- Crompton offers its Celogen family of exothermic CFAs, which can be used to foam wood-polyolefin and PVC composites. Techmer PM has three new standard CFA masterbatches for wood-polyolefins. These are typically custom formulations including color and other additives.
- Which lubricant is best for wood PP & PVC composites?
- Lonza Group has developed a more advanced alternative to its standard EBS (Acrawax C) plus zinc stearate. Glycolube WP-2200 is a new proprietary amide lubricant that contains no metallic stearates. It reportedly performed well in wood-HDPE field tests and has potential for wood-PP and wood-PVC composites.
- What is the difference between wood-PVC and wood-polypropylene?
- Wood-PVC is 10% to 13% and wood-polypropylene, 8%. Wood-polystyrene accounts for only 1% to 2%. Coupling agents bond the wood fiber to the resin matrix. They boost the flexural strength and stiffness—usually referred to as modulus of rupture (MOR) and modulus of elasticity (MOE), respectively, which are terms used in the lumber industry.
