Wood-plastic Decking: the difference between PE and PVC

[Tom Liu 0]

Since the concept of wood plastic and product are brought into the market, also let a person find everything new and fresh really, bring new choice for a few enterprises and consumer, subsequently, the product of a few wood plastic Products in building materials market.

The main wood-plastic materials are divided into PE wood-plastic and PVC wood-plastic two categories.

PE wood-plastic products are mainly based on outdoor garden construction, such as guardrail, floor, garbage can, flower pool, tray and so on. PVC wood-plastic products are mainly indoor some decorative materials, such as doors, floors, foot line, door cover and so on.

PE wood plastic materials are mainly secondary and tertiary PE recovery materials plus wood powder, calcium powder and a small amount of modifier. PVC wood plastic materials are mainly PVC resin powder, PVC recycling materials, wood powder, stone powder and some modifiers and so on.

The preparation of PE wood plastic (PVC Ceiling Panel) products mainly adopts the cold promotion method, so each process is roughly similar. The cost control of finished raw materials depends on the content of filler, so the quotation is basically the same. The preparation of PVC wood-plastic products can be divided into vacuum moulding, cold push method, vacuum moulding is mostly low foam products, and the cost control of low foam wood-plastic products vary greatly, and the product quality (refers to the rigidity, toughness and tensile strength) vary greatly.

As far as I am concerned, the development and production of wood-plastic products.

first of all, are PE wood-plastic products. Its advantages and disadvantages are as follows:

• (1) PE wood-plastic material is excellent in water resistance and corrosion resistance;
• (2) PE has poor antioxidant and anti-light decomposition ability, and even the effect of adding antioxidant and UV absorber is not ideal, which can lead to poor product strength and colour fastness, and limited outdoor service life of the product;
• (3) it is easy to deform and bend when heated, but the effect of thickening or porous hollow structure is better;
• (4) the product surface colour is single, without wood sense, and the aesthetic effect is poor. In terms of these properties and characteristics of PE wood-plastic materials, I think trays, building templates, container pads and other places that are not exposed for a long time and where visual aesthetics is not required are more suitable for development and utilization.

Secondly, the low cost of PVC wood-plastic products, good processing, surface decoration and other aspects of performance are taught PE wood-plastic superior, mainly in:

• (1) Washroom PVC Panel can be made of new or old materials, which is easy to modify. The amount of filling depends on the quality of the product;
• (2) PVC can be made into low-foaming wood-plastic products so that the cost is lower, the use of co-extrusion (double-material multi-material co-extrusion or steel-plastic co-extrusion), strength and wood grain sense is good;
• (3) PVC can be secondary processing of a variety of surface decoration or paint, including UV paint, beautiful products and good colour fastness;
• (4) the waterproof and anticorrosive property of PVC wood products is also superior.

On the characteristics of PVC wood-plastic material, wood plastic products in interior decoration materials (such as floor, the line that play a base, decoration, door cover line, etc.), furniture, decorative plate with boards (such as furniture, etc.), building decoration materials (such as exterior wall hangs Taiwan, sound insulation board, wallboard, etc.), the botanical garden decoration materials (such as guardrail) with wood plastic and wood may be a promising direction of development.
