The Main Components Of Wood Plastic composites Product

As you may already know, there is a lot of things that need to be added to the wood flour and recycled plastic product mixture so as to stay together. Without these components, the wood plastic product cannot be created. That said, here are the main components of these wood plastic components.

Raw material content

The main ingredients of WPC are wood and plastic. It is important to know what proportions make up a good WPC product. In any WPC product, the wood powder and wood particles constitutes about 60% of the whole product. The 60% is gotten from mixing ground wood particles. High-intensity plastic is about 30%, and other additives that improve the quality of the product are about 10%

Wood powder

Due to the amount of trees and wood particles around us, you can find wood anywhere. All you need to do is look around you. However, getting wood powder and wood fibres can be a little bit more tricky. The best places to find wood are in places where they process wood and forest nurseries. These places tend to have a lot of wood powder residue to use. Alternatively, you can find wood powder,landscaping timbers, and natural lumber at other places like crop straw, and from processing wasted wood.


The most common type of plastic used to make Wood-plastic products are the waste thermoplastics. These waste thermoplastics include PE, PP, and PVC. You can use plastic bags, plastic bottles, and other plastic waste. But outdoor wpc products are usually add PE plastic, because it can better withstand the outdoor environmental impact.

The best thing about these products is that you can find them anywhere. People tend to throw away a lot of plastics away, so you can easily find some to recycle.

10% additives

Other additives and synthetic materials are added so as to improve the quality of the product. Antioxidants, anti-UV agents, insect repellents, and preservatives are among the commonly used additives.

The combination of these preservatives and additives protect the wood plastic composite product and polyvinyl chloride from getting eaten by termites, and reduce its susceptibility to decay, cracking, and fading. It also requires less maintenance.

After the combination, extrusion and molding process has started, the production of final shape will come next. These are mainly used in the building process, logistics packaging, and other industries to increase durability.

The Production Process of wpc decking

1,First mix PE plastic and wood fibers or other timber alternatives, add the pigment of choice, we can get wood plastic raw materials.

2,The desired shape is then extruded through a mold in a high-temperature machine and taken through a process called injection molding. In some cases, old materials are re melted and mixed with the new product.

3,The third step is to cut the boards and pack them into a pallet according to customer’s requirements in order to improve durability.

As a result, the client can obtain the products and use this unique combination of product in different outdoor construction projects. It is also used to make several products such as WPC stands. As shown in the following picture:

The Main Classification Of Wood-Plastic Products

Now that you know how wood-plastic products are made, it is important for you to learn about the main classification of a WPC decking.

PE Composite Products

PE WPC deck are products mainly used for outdoor garden products. This means that you can use it to produce things like flower ponds, garbage cans, pallets, etc. You can also use it for outdoor garden construction projects such as flooring and guardrails.

The main advantage about PE WPC is that this wood-plastic composite has amazing water highly resistance. You won’t have to come home to find a waterlogged garden when it rains. It also has high corrosion resistance, high hardness, and is environmentally friendly.

PVC Composite Products

These forms of wood-plastic composite is extremely common. This is because they are way less expensive than PE Wood.

For decoration, you can easily use either a surface decoration, also its highly resistant water absorption. Of the two, pvc decking is more suitable for indoor decoration.

The Differences Between PE Composite and PVC Composite

While PE and PVC Wood plastic composites are quite similar,  they also possess quite a few differences, some of which are:

Different raw material

The first thing that differentiates these two products is the difference in ingredient. For PVC wood plastic, the raw materials are mainly resin powder and recycled plastics. On some occasions, you can find stone powder, modifiers, and so on.

On the other hand, PE wood plastic raw materials are secondary or tertiary recycled raw materials such as wood powder and calcium powder. Due to the fact PVC wood plastic uses pure materials instead of recycled plastic, it remains the more expensive variant.

Different production methods

The form of PVC composite production is mainly divided into vacuum forming, three-roller suspension, and the cold-push method. In contrast, the main way to produce PE composite is by the cold push method.

Wood composite product has become extremely popular. Now, people all over the world are choosing to use wood-plastic for their decking, wall cladding, railings and fences due to the fact that it’s stronger and more durable compared to pure timber.

The above are crucial facts to know about Composite decking, including how the main components, the production process. It also highlighted the difference between using PE and PVC composite.

Hopefully, this article would better inform you on the options you have, and the best one for you to pick keeping things in mind such as your budget, weather and so on.
