As the biggest and longest exporter of WPC (wood plastic composite ), China already has a very mature process for WPC (outdoor decking ) production and sales, but each supplier has different choice and proportion of raw materials Here based on our experience, from the raw materials to let us know why on the surface looks like the same wood plastic, quality will be so different. Also help everyone better according to their own needs to choose high-quality suppliers.

Plastic:

Plastic is recyclable plastic (can be used again) , first-class plastic, no impurities, environmental protection, plastic packaging is good, can be wrapped wood powder. There are factories cheap, may be the use of secondary plastic, tertiary plastic or even garbage plastic, plastic grade higher, less magazine composition, plastic wood raw material selection directly affects the quality of plastic wood. If the impurity composition of the plastic is high, the proportion of the plastic itself is small, nature can not cover wood flour well.

Wood flour:

In order to achieve the perfect fusion of wood flour and plastic, not only have strict requirements for plastic, wood flour is also required, with the weight of the more fine wood flour, powder surface area, wood fusion needs the higher proportion of plastic; On the contrary, the coarser the wood powder is, the smaller the surface area of the powder is, and the lower the ratio of plastic to plastic is. After many years of experiments, the wood powder is the best, the particle size is between 80-100 Mesh, the powder is too fine, the processing cost is high, the plastic composition is more, the cost is higher, but the plastic wood product is too high; If the powder is too rough, low processing costs, less plastic composition requirements, but the plastic molding wood products fusion is not enough, more fragile, easy to crack.

Accessories:

color powder is mainly used to match the color of plastic wood materials. At present, inorganic color powder is mainly used for PE plastic wood. Outdoor color fading resistance is better. It is different from organic color powder used for indoor PVC

ECOLOGICAL WOOD Organic pastels are more vibrant. The main function of the anti-ultraviolet absorbent is to improve the anti-ultraviolet ability and anti-aging property of the plastic wood. The compatibilizer is an additive which promotes the numerical compatibility of wood flour.
