Advanced Sensor Technologies chooses Solvay’s Ryton® PPS for chemical- and heat-resistant sensor housings

Solvay, a leading global supplier of high-performance polymers, announced today that Advanced Sensor Technologies Inc. (ASTi) selected Ryton® polyphenylene sulphide (PPS) to mould protective housings for two industrial-grade sensors.

The sensors, designed to evaluate either pH or oxidation-reduction potential (ORP) in industrial processes, are encased in housings moulded from Ryton® R-4-230BL, an advanced 40% fibreglass-reinforced PPS compound that combines improved processability, excellent rigidity and strong resistance to chemicals even at high temperatures.

ASTi, a designer of electrochemical sensors for laboratory, medical and industrial applications, chose to encase its solid-state pH and ORP sensors within housings moulded from Ryton® R-4-230BL to protect them from the harsh environments of inline process control and monitoring applications. The particular grade of Ryton® PPS that ASTi chose offered the optimal balance of superb processability, strong resistance to a wide variety of corrosive chemicals and excellent dimensional stability to allow moulding of complex components with very tight tolerances.

Ryton® PPS reliably retains its chemical resistance and rigidity even after prolonged exposure to temperatures up to 200°C (392°F) and, depending on the application, can maintain its properties for short periods at temperatures reaching 260°C (500°F).

“ASTi has increasingly relied on Solvay’s broad selection of advanced polymers to develop products for medical, biopharma and industrial applications, but we found Ryton® PPS’s unique property profile best suited the environment in which our new pH and ORP sensors would operate,” said Martin Patko, President and Founder at ASTi. “Ryton® PPS promises to optimise the performance and lifetime of these sensors as well as future applications that require a combination of chemical resistance, thermal stability, electrical properties, and rigidity.”
