Summary: It is Wood-Plastic Composites (WPC), a new type of composite material that has emerged worldwide in recent years. It uses polyethylene (PE), polypropylene (PP), and polyvinyl chloride (PVC), etc., to replace conventional resin adhesives, and mixes them with more than 35%-70% of wood flour, rice husk, straw and other waste plant fibers to form a new wood material. Through extrusion, molding, injection molding and other plastic processing technologies, it produces boards or profiles.

1. What is wood-plastic composite?

Wood-plastic composites (WPC) are a new type of composite material that has emerged worldwide in recent years. They utilize polyethylene (PE), polypropylene (PP), and polyvinyl chloride (PVC), etc., instead of conventional resin adhesives, mixed with more than 35%-70% wood flour, rice husk, straw, and other waste plant fibers to create a new wood material. Through extrusion, molding, injection molding, and other plastic processing techniques, it is processed into boards or profiles. It is mainly used in building materials, furniture, and logistics packaging industries. The material formed by mixing plastic and wood powder at a certain ratio and then hot-extruding it is called extruded wood-plastic composite.

2. The Wood-Plastic Industry

With the expansion of the real estate market and the rapid development of the construction industry, the demand for wood has been increasing. At the same time, people's environmental awareness is also constantly improving, and the industry chain of using wood-plastic composites to replace wood has gradually flourished. Because wood-plastic composite materials contain plastic, they have a good elastic modulus. In addition, due to the inclusion of fibers and thorough mixing with plastic, they have physical and mechanical properties such as compression resistance and bending resistance comparable to hardwood, and their durability is significantly better than ordinary wood materials. The surface hardness is high, generally 2-5 times that of wood.

With the expansion of the real estate market and the rapid development of the construction industry, the demand for wood has been increasing. At the same time, people's environmental awareness is also constantly improving, and the industry chain of using wood-plastic composites to replace wood has gradually flourished. So what are the advantages and disadvantages of wood-plastic products?

Advantages of PVC Wood-Plastic Products:

(1) It has excellent physical and chemical properties, a similar wood appearance, but will not crack or warp, has no wood knots or grain, high hardness, and is waterproof and moisture-proof. It fundamentally solves the problem of wood products rotting, swelling, and deforming after absorbing moisture in humid and watery environments, allowing its use in environments where traditional wood products cannot be used. It is rodent-proof, insect-proof, and termite-proof, effectively preventing insect infestation, acid and alkali resistant, corrosion resistant, has good water absorption, and extends service life.

(2) It comes in a variety of colors. It has a natural wood texture and can be customized to your desired color. It has the secondary processing properties of wood, can be sawed, planed, glued, and fixed with nails and screws, and is easy to repair. Maintenance costs are low, and the service life is longer than that of wood.

(3) It is highly malleable and can easily achieve personalized shapes, fully reflecting individual style.

(4) It is highly environmentally friendly, pollution-free, harmless, and recyclable. The product does not contain benzene, the formaldehyde content is 0.2, lower than the EO standard, which is the European environmental protection standard, and its recyclability greatly saves the amount of wood used, suitable for sustainable national policies, and benefits society.

(5) It has high fire resistance, can effectively flame retardant, reaches B1 fire rating, self-extinguishes when encountering fire, and does not produce any toxic gases.

(6) The material sources are wide, and the price is low; both new and recycled materials can be used.

Disadvantages of PVC Wood-Plastic Products:

(1) The moisture content in the wood-plastic material is too high;

(2) The amount of antioxidant used is too low;

(3) Some wood-plastic flooring products will fade;

(4) The surface of wood-plastic flooring is too smooth and slippery when wet. (PVC eco-friendly products, eco-friendly crosslinking agents, eco-friendly plasticizers)
