HNBR or hydrogenated nitrile butadiene rubbers
HNBR or hydrogenated nitrile butadiene rubbers are based upon a compound of saturated copolymer of acrylonitrile and butadiene. The physical and chemical properties of an HNBR compound can vary dramatically depending on the polymers composition.
AFT Fluorotec’s AF1300 range of HNBR compounds can be used in applications involving hydrocarbon mineral oils, butane, propane, mineral oils and crude oils, but also for many diluted acids and bases.
Generally service temperature is from -30°C to +160°C Specific HNBR compounds also exhibit excellent toughness, abrasion and wear resistance, making them ideal for use in harsh oilfield applications and sealing applications involving compression.
Fluoroelastomer Seals and O Rings
We can offer genuine Viton fluoroelastomer seals and O rings, AF 1600 grades of Viton offer seals that are resistant to chemical attack, compatible for use with hydrocarbon fuels and at elevated temperatures from -25°C to +210°C.
Our Viton materials can be CNC machined into standard and special profiles to large diameters up to 1800 mm.
EPDM seals and O Rings
EPDM is an elastomeric compound based upon ethylene propylene diene. AF 1400 EPDM rubber and elastomeric materials offer good resistance to water, steam, certain ketones, alcohols, and non petroleum based brake fluids. AF1400 EPDM seals also offer good resistance to ageing from weathering and ozone.
EPDM rubber can be used to -55°C and to +150°C.
Silicone Seals and O Rings
Our AF 1700 range of silicone elastomers have an operating temperature range of -55°C to +210°C depending on the grade is use. Silicone is generally used for static sealing applications. It offers good electrical insulation, resists microbiological growth, has low toxicity and low thermal conductivity.
AF 1700 silicone rubbers also provide a material that resists attack from oxygen, ozone, and UV light.
Aflas Seals and O Rings
Aflas is a fairly unique material that is fluoroelastomer based, and hence offers good chemical resistance. It is a copolymer of tetrafluoroethylene and propylene with service temperatures from -15°C to 210°C.
AF1501 Aflas has good resistance to oils, and offers good electrical insulation, as well as a high continuous service temperature. Aflas is the material of choice for heavy oil field, diesel service and industrial applications involving oil and steam.
All of the above materials are available in other colours and FDA compliant grades.
E131-B85 is a black Ehtylene Propylene Rubber, commonly referred to as EPDM. This material is often used in hot water steam applications as well as in fire resistant fluids where synthetic oils are used. EPDM materials are also used in bases, acids and alcohols. EPDM is also used for brake fluids, but we recommend observing local safety-regulations before installing an EPDM seal in breaking systems. EPDM is not resistant to mineral- vegetable- and animal oils.
