In the next operation, reaction mixture is stripped free of monomer to at least below 1 ppm. For a good stripping performance, polymer grains must be porous. In modern plants, steam stripping columns are used. In older plants, stripping is done directly in the polymer vessel or in the tank into which slurry is transferred after polymerization.sp.info How does heat transfer take place in plastic?The heat removed from the plastic is equal to the heat given off as the plastic temperature drops from 180°C to 40°C plus the heat of solidification which is equal to the heat of fusion but opposite in sign. As the plastic solidifies and the molecules stop moving randomly, heat is liberated.See all results for this questionsp.info Is the Chem Group A heat transfer company?Chem Group is an authorized distributor of Petro Canada’s CALFLO™ line of heat transfer fluids.
