Injection Molding Wood-Plastic Composites Plastics Technology

Wood-fiber/thermoplastic blends have already made a name for themselves in extruded decking and fencing boards. Now they are moving into injection molding. Some injection molders are hesitant to experiment with new materials like wood-plastic composites WPCs .【Get Price】

Foaming Expands Possibilities for Wood-Fiber Composites .

Composites with less wood fiber are generally easier to foam than more highly loaded ones but wood-fiber type and size play a role. Longer fibers give the composite strength but also give the foaming gas a pathway to escape. Foaming is easier with amorphous polymers like PVC and PS than with crystalline ones like PP or PE.【Get Price】
