Polyester anti-corrosion board is mainly made of flame-retardant polyester resin and reinforced with surface felt and knitted felt. Alkali free glass fiber short cut felt is used as a reinforcing material and is produced through the current domestic composite material extrusion technology with a tensile strength of 80KN (8 nap), high temperature, and high pressure. The product design is reasonable and solves the problems of aging resistance, poor density, unstable geometric dimensions, and low fire resistance of ordinary composite materials. It also solves the problem of corrosion resistance of metal tiles and the problem of deformation and hail impact resistance of synthetic resin (PVC) tiles.
