Fireproof building construction materials 

Introduction of WPC Foam Board

Rainbow Bridge WPC Board is made by PVC resin and wood powder(or bamboo power) at a certain ratio, added with special additives and extruded at high temperature.

It has the sense of wood, but it is harder,smoother and stronger. It is light weight, waterproof,no moisture absorption, no mildew,UV-resist,anti-corrosion,acid and alkali resistance,easy to assemble, high turnover rate, no crack,less seams, sawing, can be nailed, can be processed into any length, recyclable and many other advantages.

It can completely replace wood, plywood, poly-board, shaving board and MDF. It is widely used in many fields:

construction shuttering, building and pholstering, furniture, especially for the cabinet in kitchen & bathroom, advertising, traffic and transit, industry, etc.

Size: 1220*2440mm, 915*1830mm
Thickness: 12~24mm
Density: 0.65~0.75g/cm3
Color: white, black, red, blue, yellow, green, gray, or as your request
(Remark: Normally Greyish-green,dark yellow,)

WPC Construction Template

Install instruction and notice:

1- Easy to nail, drill, and cut and size you want;
2- not more than 240mm between steel pipes;
3- Strengthening nails connection, there should be 10mm from board edge.
4- When demould, don't be violent.

Advantages in building construction----used as formwork board

1. Easy to take off from the concrete. Concrete wont be sticky to this kind of board.
2. Adjustable size. The board size is adjustable according to the requirement from the builder.
3. Shiny and  Smooth surface.  The concrete is with smooth surface after stripped .
4. Steady quality. The wpc board is with very good mechanical strength, It can work well between -20 degree and 100 degree.
5. Easy to install and save labor. It is in light weight and can be processed to any shape and size, save labor.
6. Product attribution is good. wpc board is antisepticise, inflaming retarding and waterproof.
7. Energy saving and environment protect.  
8. Lower cost. Turnover can be up to over 30 times, so deeply reduce the cost.

2. Material Safety
Low flame spread;High slip resistance;Excellent thermal properties;Contains no toxic chemicals or preservatives
Environmental friendly;Can be recycled with 100%;No sting of wood;

3. Install & Maintain easily
Easy to produce and easily fabricate;Easy to cut, fix and glue|;Easy to plane;Easy to tenon, drill and nail;Require less routine maintenance;no need staining & water Sealant;

4. High Strength
Outstanding screw and nail retention;High impact resistance;Great Compressive-tensile-shear strength;Modulus of elasticity: 20% greater than PVC, does not require reinforcement(in most applications).

5. Good appearance & nice touch
Natural feel & wood touch;Broad range of finishes and appearance;Multicolor, and needn't to painting;Available for both sides.

6. Longevity

WPC formwork ( 2014 cheap building material ) performance:
1- Level and smooth surface: 
2- Light weight and easy for assembling;
3- Easy demould, no need brush parting agent;
4- Stability and weather proof: during -20degree and 60degree, no shrinkage, no swelling, no cracking, no deformation,  Alkali-resistance,  corrosion protection, fireproof, waterproof, heat resistance, electric insulation;
5- Good variability: the shape and the specification could be changed according to the construction situation.
6- Low cost: recyclable, longlife span;
7- Energy conservation and environment-friendly etc.
