ROVEX advances fiber-reinforced polymer (FRP) technology by cross-linking continuous strands of glass fiber with polyurethane polymer resin in a heat-accelerated continuous chemical reaction process called pultrusion.

Pultrusion:  Deceuninck Rovex technology utilizes a specialized pultrusion process for providing high-strength products designed for manufacturing door and window parts. These PUR products offer many excellent performance features compared to other pultrusion technologies like those based on vinyl esters or polyester types.

The Rovex process pulls chemically-modified glass fibers through an injection box during which the glass fibers are impregnated by polyurethane (PUR) reactants. These PUR components, often referred to as the “iso” and “polyol,” covalently react forming urethane linkages connecting chains. In addition to the in-situ polymerization process, the modified glass fiber surface participates in covalent bonding interactions. The final product is comprised of 80% glass fibers that connect to a matrix of polyurethane linkages.
