Process Seals develops ‘clean’ white sealing material

ELGIN — Process Seals recently expanded its portfolio of ethylene propylene diene Monomer materials with a new white material specifically developed to meet the requirements of hygienic design applications for the pharmaceutical, food and beverage, and biotech industries.

The white 70 EPDM 253815 material was developed for use in O-rings, molded parts and butterfly valve seals in hygienic applications where cleanliness is crucial. Process Seals replaced the carbon black particles that are traditionally considered indispensable for mechanical durability and chemical resistance with special mineral fillers to create the white compound that gives the perception of cleanliness.

“In food, beverage and pharmaceutical production, both critical processes and aggressive media require highly durable seals,” said James Lippert, U.S. sales manager, Process Seals. “With its extensive industry and material knowledge, Process Seals works to continually develop new materials that provide equipment manufacturers and facility operators customizable solutions to address their challenges.”

In extensive testing, the white EPDM demonstrated outstanding mechanical and chemical durability, especially in Clean-In-Place / Sterilization-In-Place processes. In accordance with DIN ISO 1817, the material was tested in cleaners, steam and disinfectants. After more than 168 hours in the media, the volume change of 70 EPDM 253815 remained below five percent. The material is certified and approved in accordance with United States Pharmacopeia Class VI, Food and Drug Administration and EC 1935/2004 regulations, and is guaranteed to be free of animal derived ingredients.

Process Seals, a division of the international Freudenberg Sealing Technologies, is a sealing solutions supplier for the food and beverage, and pharmaceutical industries. As a specialist in process engineering applications, the company has more than 160 years of technological knowledge and market expertise.
