Wood Pvc Formulation

Wood–PVC composites: formulation optimisation A standard rigid PVC profile formulation has been optimised to better accept the wood fibre presence in terms of compatibility, dispersion level, rheology, extrusion output, physical and mechanical properties of extrudates. Several different additives have been evaluated at different use levels. Process aids and lubricants...

Wood-plastic composite - Wikipedia The types of plastic normally used in WPC formulations have higher fire hazard properties than wood alone, as plastic has a higher chemical heat content and can melt. The inclusion of plastic as a portion of the composite results in the potential for higher fire hazards in WPCs as compared with wood. Some code officials...
