Brief:UPR(unsaturated polyester resin):large volume; high-speed of reaction and well distributed heat conductivity, easy operation and low cost. UPR plant is the crucial equipment used to produce unsaturated polyester resin. The plant consists of reaction pot, vertical still,horizontal condenser, water storage tank, oil spilling groove, pipeline (double rare). The contacted part of the plant and material is made of stainless steel. Features of unsaturated polyester resin plant. 1) Capacity: 100~20000Liters. 2) Jacket and coil pipe are used together for heating and cooling. 3) High-speed reaction and well distributed heat conductivity. 4) Consistent resin quality. 5) easy operation and low cost.
