PEEK and PPA grades get NSF approval for food processing and household appliances

Solvay Specialty Polymers : 19 April, 2015  (New Product)
Newly certified grades expand Solvay's Polymer solutions for highly demanding food processing and consumer appliances.
The National Sanitation Foundation (NSF) has certified seven Amodel polyphthalamide (PPA) and KetaSpire polyetheretherketone (PEEK) resin grades under its NSF/ANSI 51 standard for food equipment materials.
 
NSF’s certification greatly expands Solvay’s broad and growing portfolio of high-performance materials targeting the manufacture of commercial food service equipment for aviation and rail transport, as well as hotel, catering and domestic applications. Target applications encompass boilers, beverage dispensers, water tanks, cutting boards and stock pots, in addition to related components like tubing, gaskets, chassis, pistons and valves.
 
“As one of the food service industry’s most recognized and requested certifications, the NSF standard is an essential criterion for materials suppliers hoping to compete in this dynamic industry,” said Andreas Lutz, global market manager for consumer goods at Solvay Specialty Polymers.
 
Three glass-filled Amodel PPA grades, offered as black and naturally coloured options, constitute six of the newly certified grades. They include Amodel FC-1140 (40% glass fibre), Amodel FC-1150 (50% glass fibre) and Amodel FC-1160 (60% glass fibre). The seventh NSF-certified product is KetaSpire KT-880 NT PEEK, an unreinforced resin characterised by outstanding wear and abrasion resistance combined with high surface hardness, fatigue performance and chemical resistance. All of these materials are certified under NSF/ANSI 51 for applications reaching 100C, but retain their mechanical properties at continuous-use temperatures up to 120C. They provide reliable, long-term performance, as well as strong resistance to oils, greases, hot water, steam and common household cleaners and descalers.
 
These Solvay grades all currently meet corresponding food service regulations under the US Food & Drug Administration (FDA) and EU Commission. Compared to competing thermoplastics, such as polybutylene terephthalate (PBT), polyoxymethylene (POM) and aliphatic polyamides (PA6 and PA66), Solvay claims its advanced polymers provide a higher level of performance over a wide temperature range in harsh food service environments. In addition, their excellent thermal and dimensional stability, low moisture absorption and heat/steam resistance make them candidates for replacing metal parts.
