Due to the lack of wood resources, people's use, wooden corners, bark, quick materials and other manufacturing sheets have saved costs to a certain extent, and it also alleviates the consumption of wood resources. But the harmful substances in the artificial board have become a major culprit that endangers human health. In the process of choosing decoration materials, people pay most attention to green, healthy and environmental protection. However, the current decorative materials that are uneven are often misleading the choice of users. The sharing for everyone today is the truly green environmentally friendly decorative material——wood plastic composite material (plastic wood).

The manufacturing process of wood plastic composite material

Use polyethylene, polypropylene, and polyvinyl chloride to replace the usual resin adhesives, mixed with more than 35%-70%of wood powder, rice shell, straw and other waste plant fibers.After squeezing, mold pressure, injection molding and other plastic processing processes, plates or profiles are finally produced.

Classification of wood plastic composite materials

According to materials, domestic plastic wood is divided into two categories: PE plastic wood and PVC plastic wood. In terms of production methods: The preparation of PE plastic wood products mainly adopts cold push method; the preparation of PVC plastic wood products can be divided into vacuum forming, cold push method, and three rollers to curb.

In terms of raw materials: PE plastic wood materials are mainly two and third -level PE recycling materials plus wood powder, calcium powder and a small amount of modifiers. The materials for manufacturing PVC plastic wood are mainly PVC resin powder, PVC recycling materials, wood powder, stone powder and partial modifiers.


In terms of performance: PE wooden plastic products are heavy, high hardness, crispy, and creep. PVC wood plastic products are light, poor, poor, good toughness, creep, and large PE wood plastic products.Anti -insects and termites. Effectively eliminate insect invasion and extend the service life.There are diverse colors. It has both natural wood and wood texture, but also customizes other colors as needed.

Waterproof and moisture -proof. The problem of being easily rotted, expanded and deformed after moisture in the humid and multi -water environment in the humid and multi -water environment.Taking the floor as an example, the gap left by the two floors during installation helps to drain, and can be used in an environment that traditional wood products cannot be applied.

Strong plasticity, good processing performance, easy to install and clean.


High environmental protection, pollution -free, non -rigorous, recyclable. The product does not contain benzene, and the formaldehyde content is 0.2, which is lower than the EO level standard. It is the top environmental protection standard for European -level Europe. It can be used circularly and greatly saves the amount of wood. It is in line with the national policy of sustainable development.

High fire protection. It can effectively fire flame retardant, and the fire prevention level reaches B1 level. In the case of fire, it does not produce any toxic gases.

The sound absorption effect is good and the energy saving is good, so that the indoor energy saving is as high as 30%.
