It is a PVC resin with Rice husk additive, whose characteristics make the product water resistant, UV resistant and 100% recyclable, thus suitable for outdoor use, for processing with normal woodworking tools. The use of rice husk whose main component is silicon oxide, allows the material to be loaded with a silicate-based component, which is a chemical element that has very low water absorption (they are almost hydrophobic compounds) and high hardness.
The presence of rice husk has a synergistic effect with PVC, achieving a noticeable improvement in flexural modulus in that if a rigid PVC has a flexural modulus ranging from 2200 to 2400 MPa ALFAFIBER has a flexural modulus of 3560 MPa.
The product can be used for faux wood finishes (including brushing) or coated by co-extrusion to achieve the desired surface. Its chemical composition also provides high stiffness, very low shrinkage and coefficient of thermal expansion.
