boron in wood protection and biocides - fighting back fire ...

unfortunately, unprotected wood fiber in wpcs can be susceptible to destructive organisms, such as decay fungi. with a typical wood-to-plastic ratio of 50:50, fungi can destroy 20-40% of wpcs’ wood component. to provide affordable, long-lasting protection of wpcs against decay fungi, consider preservation with borates as a wood fungicide.

wood–plastics composites with better fire retardancy and ...

1. introduction. wood–plastic composites (wpc) combine the best properties of the neat components and can show outstanding performance. when comparing with potential traditional competitors, one find that wpcs offer better thermal and acoustic isolation than aluminium, and better durability and lower maintenance than wood often at a lower price than neat plastics.

wood-plastic composites are more desirable with fire ...

studies showed that increasing the wood fiber content in wood-plastic composites significantly improved the fire performance to that of the plastic alone. adding fire retardant chemicals, particularly ammonium polyphosphate, was also shown to be effective in improving the fire performance.
