Wood polymers composites

Wood polymers composites

Theory

The pellet WPC ( Wood and Plastic Composite ) is a product composed by two elements, a thermo-plastic and a vegetable material with characteristics mostly inert to temperature and pressure.

The materials so obtained are equal or similar to the wood, but with greater performances; in fact they are mainly used to replace the wooden products.

The WPC pellet is generally produced using compounds of the following materials:
• Plastic material virgin or recycled one
• Inert vegetable fibers
• Mineral fillers
• Auxiliaries of process

Filtec in Compounding WPC

To avoid the deterioration of the material during the pelletizing operations, Filtec suggests the underwater pelletizing. So it becomes basic to be able to supply a pellet with an acceptable residual humidity. The Compounding WPC segment in the plastic material field asks a greater percentage, this aspect introduces particular difficulties.

Polymers used for WPC pellets are:
