NBR or Nitrile rubber is available in a number of shore hardness variants and grades, our AF1200 range of NBR’s or acrylonitrile-butadiene rubber, are excellent engineering materials for general purpose seals and O rings, AF1200 NBR’s provide good resistance to mineral oils and greases, and fuels such as petrol, diesel, and fuel oils; and also can be used with animal and vegetable oils and hot water. Operating temperatures are relatively low -40° to 100°C, with intermittent use to 120°C.

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.
