Polycarbonate Synthesis Process

Resin concentration monitoring in polycarbonate synthesis process 

Polycarbonates are thermoplastics used for manufacturing of bottles, food and drink containers, windows, computer and TV housings, furnishing, etc.

Typically, polycarbonate plastic is produced by synthesizing bisphenol A (BPA) and phosgene (carbonyl dichloride, COCl2) in a methyl chloride solvent. After the reaction, the polymer solution is centrifuged and filtered, and then concentrated and dried.

Vaisala Polaris™ process refractometer is used to monitor the concentration of resin in solvent to maintain precise control of the manufacturing process. 

Appropriate equipment with hazardous and intrinsic safety approvals are available.
