How WPC Wins Over Traditional Wood In Case Of Fire?
Natural wood and wood plastic composites (WPC) are
2 common types of outdoor decking materials used in the
market today. We all
know that traditional wood can catch fire easily, but wood plastic composite
(WPC) floors are made to be fire resistant to keep your property and, more
importantly, your family safe. Researchers have found that the wood fiber content in wood plastic composite planks makes them flame
resistant and a better choice than wood.
WPC planks are popularly being used in a wide range
of exterior applications which include gates, louvers, partitions, sunscreens,
signage, wall & ceiling cladding, decking, landscaping and a whole lot more
exterior products around homes. Being a flame proof material, WPC planks do not
burn with flame and allow fire to spread keeping your property safe. Whereas,
traditional wood planks supports the fire to spread as it burns with flame.
So what makes WPC retardant?WPC consist of
plastic and wood and a combination of stabilizing agents, foaming agents, and
modifiers that are combined in a proper ratio. This perfect blend of
materials helps to get high-quality WPC planks that are resistant to fire.Several fire resisting chemicals have been utilized in
order to improve fire behavior of WPC. Adding such chemicals, particularly ammonium
polyphosphate has shown to be effective in improving the fire performance of
WPC.
Wood catches fire and keeps on burning even if the heating source is
removed. This is not the case with WPC, as it is a polymer based product. It is
self-extinguishing and doesn’t ignite fire when in touch with a fire source.The fire-retardant properties of WPC planks have been enhanced by
adding halogen-free fire retardants to the wood-polymer mixture during the melt
phase.
Fire occurs when a substance becomes hot enough to reach ignition
temperature (around 150 degrees C) in the presence of sufficient oxygen. The
density of the wood plastic composite planks is much higher, and so is the
melting point. While comparing, the limiting
oxygen index of traditional wood board is 27%, and that of an untreated WPCboard is 19% which reduces the material’s flammability. Thus WPC wins over natural wood and is considered
as one of the best cladding/decking material for fire prone areas.
WPC gives you the best of both worlds. Looking much like natural wood,
WPC planks are extremely durable and resistant to fire, damage, water, stains,
mold, UV fading, and they don’t splinter or crack. They can also last for
decades with no maintenance. With modern technology, you can achieve a
gorgeous, realistic wood look without the challenges of traditional wood.
