Newman Quality Viton Compounds
Newman a Viton A, GF & ETP Gasket Manufacturer, creates its Viton™ seals and FKM gaskets from proprietary compounds made with genuine Viton™ resins from Chemours. This results in excellent mechanical, chemical, heat and steam resistance (all USP grades tested to 500 clean steam sanitization cycles). Although originally known for excellence in the petroleum and automotive industries, Viton™ now finds wide application in the food, beverage, and biopharmaceutical processing industries. With excellent long-term durability, Newman Viton compounds are found in many pump and agitator mechanical seals where years of continuous use is required. Unlike Teflon™ (PTFE), they can also be used in vacuum service due to their excellent sealing properties and low gas permeability. With somewhat limited low temperature flexibility, some grades have still been used in static sealing applications down to -65°F(-53°C). Viton™’s upper temperature limit is stellar: allowing use to 450°F (232 °C) and 600°F (315 °C) short term.

Viton™ A (fluorocarbon rubber)
The most cost-effective Viton™ compounds from Newman are made with Viton™ A. Representing the bulk what the high purity industry uses when FKM oil resistance is needed, most AS568 standard O-rings sizes, sanitary clamp gaskets and cord profiles have immediate availability from Newman. Newman Viton A also has excellent steam resistance unlike many other FKMs on the market. However, Viton™ A has limited use in basic solutions and with ketones and esters… enter Viton™ with APA architecture!
Viton™ “GF” and Viton™ “ETP” made with Advanced Polymer Architecture (APA)
In response to the need for FKMs with better base and chemical resistance than Viton™ A, Newman Sanitary Gasket Co offers proprietary compounds made with Viton™ Advanced Polymer Architecture (APA). Among these are Newman compounds containing Viton™ GF and Viton™ ETP.
Newman compounds made with Viton™ GF are peroxide-cured and show enhanced resistance to basic cleaning solutions (e.g. caustic) often used in the food and biotech industries. Viton™ GF also has better resistance to aromatics used in food processing. Newman proprietary Viton™ GF compounds still retain their excellent steam resistance and long-term durability.
Viton™ ETP reaches the pinnacle of chemical resistance for FDA and USP compliant compounds for use in high purity industries. With good resistance to acids, bases, and many esters, ketones and amines, Viton™ ETP may be a lower cost alternative for demanding processing situations like natural flavorings and harvesting areas of biopharm processing.
DuPont/Chemours and Newman proprietary compounding is the answer to your challenging demands for long lasting high purity seals with resistance to high temperatures and the broadest range of chemicals.
