Wood-plastic Composites - an overview ScienceDirect Topics

Because 200 °C is the practical upper limit for wood–plastic composite processing, resins that melt higher than this temperature – PET, for instance – cannot be used in wood composites. Plastics can be also reinforced with wood fiber leading to higher mechanical performances. Some foamed WPC products are commercial

The very low leach rate as determined by laboratory testing appears to be controlled mainly by dissolution of the zinc borate and not by diffusion. The tests show that zinc borate will take at least 20 years to
