Brominated reactive flame retardant vinyl ester resins, such as 905-2, 905-2HOI, 905-N, 915, CHEMPULSE 915-HOI, etc., have good corrosion resistance. At the same time, due to the introduction of halogen into the resin system, it has excellent flame retardant properties, and is mainly used in corrosion-resistant equipment with flame retardant requirements.
Among them, 905 series is mainly used in the preparation of FRP chimney in large coal-fired power plant because of its excellent comprehensive performance in corrosion resistance, fire resistance, good mechanical performance, stable performance and good operability. 915 series is widely used in the preparation of anode tube and shell in wet dust collector because of its excellent corrosion resistance, flame resistance and self-extinguishing property.
