FRP pultrusion equipment is used to produce various FRP pultrusion products, such as FRP rods, I-shapes, angles, squares, open webs and profiled materials. Especially the large cross-section glass fiber reinforced plastic cable tray is an indispensable equipment, and the fields involved are electrical engineering, anti-corrosion engineering, construction industry, transportation, sports and entertainment and other aspects.
Unsaturated polyester resin is the main component of the glass fiber reinforced plastic pultrusion process, and its amount reaches more than 90%. In recent years, as the requirements for the pultrusion curing system of unsaturated polyester resins have become higher and higher, phenolic resins have been gradually developed, which have the characteristics of fire prevention.
In addition to resin, reinforcement materials are also used, which are mainly used to meet the special material requirements of glass products. Commonly used aramid fiber, carbon fiber and metal fiber are bonded to the resin matrix through surface treatment. The auxiliary materials are the use of internal mold release agents and powder fillers.
