Three glass-fiber-reinforced polymers are ‘food-safe’
Ryton polyphenylene sulfide (PPS) compounds combine long-term heat resistance with excellent dimensional stability, very low moisture absorption, strong chemical resistance and inherent flame retardancy, says the manufacturer. Three new Ryton PPS products are now available for use in food-and-beverage applications. Two of them (Ryton R-4-242 and Ryton R-7-232 PPS) are entirely new products; the third (Ryton R-4-232 PPS) is a previously available product that is now approved for food-contact applications. These food-safe resins provide suitable alternatives to metal and thermosets in many applications, says the company. They comply with U.S. Food and Drug Administration NSF51 requirements, as well as the European Union’s EU 10/2011 regulations for use as a component material intended for use in food-contact applications. — Solvay Specialty Polymers, Alpharetta, Ga.
