Polyphenylene Sulfide (PPS) Resin Process

Process control for high quality polyphenylene sulfide compounds

Polyphenylene sulfide (PPS) resin is a form of engineering plastic used in manufacturing of electrical appliance components, automotive and industrial applications, corrosion preventive coatings, filter and filter bags, etc.

PPS is made form sodium sulfide and dichlorobenzene in a polar solvent. The process medium is a suspension containing PPS and sodium chloride. 

In the process, sodium chloride, NaCl must be removed to prevent corrosion and burning of chloride, and in order to produce chlorine- and sodium-free PPS resin. The final product is powdered and packaged for further processing. 

Vaisala Polaris™ process refractometer measures the NaCl dissolved solids concentration without being influenced by the undissolved PPS resin in the solution. 

Learn more about the sodium chloride measurement in PPS compounds production from the application note.
