However, the mechanical strength of this polymer is very low and cannot meet most usage requirements. When reinforced with glass fiber, it can become a composite material, commonly known as "glass fiber reinforced plastic". The reaction tank is a key equipment in the condensation reaction process of unsaturated resin.
