The materials below are used to produce our standard product line. Specialty compounds are used occasionally depending upon overall demand or special customer needs.
FEP (Fluorinated Ethylene Propylene) offers an excellent combination of properties.
- possesses a very high degree of stress crack resistance
- chemically inert
- low coefficient of friction permits viscous liquids to flow freely
- exceptional dielectric properties
- heat resistant
- retention of properties after service at 400°F (204°C) with useful properties at -454°F (-270°C)
- meets FDA 21CFR.177.1550.
PFA (Perfluoroalkoxy) is a premium resin preferred when extended service is required in hostile environments involving chemical, thermal, and mechanical stress.
- high melt strength
- stability at high processing temperature
- excellent crack and stress resistance
- low coefficient of friction allows fluids to flow freely
- resistance to creep at its high service temperature
- retention of properties after service 500°F (260°C) with useful properties at -320°F (-195°C).
- meets FDA 21CFR.177.1550.
VITON® (Fluorocarbon Rubber) is a fluoroelastomer compound which offers exceptional mechanical properties and low compression set. Has-Mor Industries, Inc. is an authorized licensee for DuPont Performance Elastomers Genuine Viton® with Viton® TracerTM Technology.
- recommended for use in hot chemically corrosive environments that are very degrading to most other rubber compounds
- for use in Aerospace, Oil and Gas, Automotive and Chemical manufacturing
- temperature range: 0°F (-17°C) to 400°F (204°C). Short periods above and below the temperature range are tolerable.
- meets or exceeds all AMS 3216G (formerly Mil Spec MIL-R-83248C, Type II, Class 1) physical and chemical requirements, 75 Durometer.
Silicone Elastomer possesses mechanical properties similar to fluoroelastomer compounds but with slightly lower compression set resistance.
- excellent heat resistance and the best low temperature flexibility of all elastomers.
- temperature range: -60°F (-51°C) to 400°F (204°C).
- meets FDA 21CFR.177.2600, 70 Durometer.
EPDM is a peroxide-cured elastomer.
- low gas permeability
- resistance to ozone, steam, water, alcohols, and brake fluids
- temperature range: -50°F (-46°C) to 300°F (149°C),
- short term exposures to -60°F (-51°C) to 350°F (175°C)
- 65 Durometer.
The temperature ranges advised are limit values and must always be considered in connection with the medium to be sealed and the operating pressure. This means that the permissible temperature for extended operation is always lower than the upper limit values.
