Kaolin acts as a filler and effective reinforcement agent
Fiberglass refers to a group of products made from individual glass fibers made into a variety of forms. It is used as a reinforcing agent for many polymer products; the resulting composite material is properly know as fiber-reinforced polymer (FRP) or glass-reinforced plastic (GRP). Basic raw materials for fiberglass products are a variety of natural minerals and manufactured chemicals. Kaolin is one of the ingredients for manufacturing fibreglass. Kaolin is used in fibreglass as a filler and also enables strengthening of the fibres integrated into the material, It also improves the integration of fibres in products requiring strengthened plastics: cars, boats and marine products, sporting goods and recreation products, aviation and aerospace products, circuit board manufacturing, fibreglass insulation, fibreglass air filters, fibreglass tanks and pipes, corrosion resistant fibreglass products, fibreglass building and construction products. The concentration of kaolin in the binder is determined by the chemical nature of the fibre, its surface composition and properties, and the textile structure of the reinforcing system.
