Expanded Ryton PPS Portfolio

For Food and Beverage Applications

Solvay, a global supplier of high-performance specialty polymers, announced today that it is adding three Ryton polyphenylene sulfide (PPS) products to its rapidly growing portfolio for food and beverage applications. Two of the additions – Ryton R-4-242 and Ryton R-7-232 PPS – are entirely new Solvay products. The third – Ryton R-4-232 PPS – is a previously available product that is now proven safe for food contact.

Solvay’s three food-safe PPS polymers are each available as natural or black-colored grades, and they target applications such as food-industry appliance components that require long-term reliability at temperatures up to 200°C (392°F). Examples include parts for deep-oil fryers, coffee machines, ovens and microwaves. Ryton PPS compounds offer best-in-class long-term heat resistance combined with excellent dimensional stability, very low moisture absorption, strong chemical resistance and inherent flame retardancy. Their high flow offers designers and molders easy processability of complex parts. All three new grades 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 repeated use in food contact applications.

Solvay’s Ryton R-4-232 and new Ryton R-4-242 products are both 40 % glass fiber-reinforced PPS compounds that raise the bar for heat resistance in Solvay’s food-contact portfolio. The latter product further offers slightly higher mechanical properties and is based on a production technology that lowers outgassing which, in turn, reduces taste and odor. The newly introduced Ryton R-7-232 product is a 65 % glass/mineral-reinforced compound that offers the most cost-competitive option for food contact applications that demand reliable, high-heat performance.

All three grades have received full V-0 Yellow Card ratings under Underwriters Laboratories (UL) UL 94 test methods – at wall thickness of 0.75 mm (0.03 in) for the new Ryton R-4-242 and R-7-232 grades, and at 0.39 mm (0.02 in) for Ryton R-4-232 PPS.
