Wood plastic profile machine
This item adopt plastic or recycling plastic (PE/PP) and fibre filling (wood flour and other fibre: rice chaff, straw staff, nut parting etc.) as main material (more than 95%), the product of which is ------“wood plastic composite”, hereinafter called “WPC”.
① WPC substitute natural wood, that protects forest resources.
② WPC uses plant fibre, that reduces environmental pollution.
③ WPC eliminate white pollution, that improves the nature environment.
