FAQ: WPC DECKING
What is WPC?
Wood Plastic Composite (WPC) is a hybrid material composed of natural wood and plastic fiber. Saw dust from fiber fillers such as pulp, peanut hulls and bamboo are mixed with new or waste plastic powder from materials such as polyethylene, polyvinyl chloride, polypropylene and acrylonitrile butadiene styrene
- 30% HDPE (Grade A Recycled High Density Polyethylene)
- 60% bamboo/wood fibre (professionally treated dry bamboo/ wood fibre)
- 10% chemical additives (anti-UV agent, stabilizers, anti-oxidation agent, colourants, anti-fungus agent, coupling agent, reinforcing agent, lubricants)
How is WPC decking produced?
Fibers, polymers and additives are first mixed together and heated to create a compound. This compound is then extruded (i.e. pushed through a die to form the WPC decking shape). After it is cooled, it then goes through a finishing process before it is ready to be used.
How does WPC compare against wood?
- As WPC does not rot or is subject to termite or insect attack, it tends to last much longer than wood.
- It does not splinter.
- It does not need to be varnished like wood.
- as an artificial material, it is dyed so it does not turn grey like natural wood. The product will often turn somewhat tan when first exposed to UV light, due to the presence of wood fiber. This is natural and temporary. The boards may then undergo a slight yellowing, but this will fade and stabilize after a few weeks of exposure.
Are splinters a problem with WPC decking?
No. Because of their composition and the way they are produced, WPC decking is splinter-free.
