This synthetic rubber is extremely resistant to the effect of fuels and oils, in particular hydraulic oils, greases,and other aliphatic hydrocarbons, acids and caustic solutions. Good physical values and, for example high abrasion resistance stability and a favourable temperature range from -25°C to +100°C protect a broad range of applications involving this rubber.

This rubber is made from NBR polymers by carrying out full or partial hydrogenation of the double-connecting butadiene proportions. Thus the heat and oxidation stability increase by means of by-oxidic networking. High mechanical firmness and improved resistance to wear characterise the materials that make up this rubber it. Medium stability is comparable with NBR. Temperature range -30°C to +150°C

Materials made from SBR (polymer made from butadiene and styrene) are used primarily in hydraulic brakes as a sealing element. Good stability in inorganic and organic acids and base, brake fluids based on glycol, water and alcohol. Should not be used in mineral oils, grease, fuels and aliphatic, aromatic and chlorinated hydrocarbons.
Temperature range from -40°C to +90°C

The field of application of this rubber cannot be attributed to the temperature range -55°C to +200°C but to the hot waters or steam that it may be able to transfer. Although the oil resistance of silicone rubber approximates that of NBR, it does not have the physical and mechanical characteristics of this material..

Apart from the typical characteristics of normal silicone rubber (VMQ), the stability of fluorine silicone rubber is still substantially above that ofoils, fuels and solvents. This applies particularly to aromatic and chlorinated hydrocarbons and alcohols. This rubber can be used over a wide temperature range from -75°C to +200°C and can interact with aggressive media e.g. gasoline, alcohol mixtures, aromatic oils and combinations of chlorinated solvents. Typical applications are seals in the fuel compartments of cars and aircraft, as well as in the chemicals’ industry.

Very good resistance to diluted acids and concentrated weak alkalis, extraordinary stability in combatting the effect of mineral oils, aliphatic and aromatic hydrocarbons as well as chlorinated hydrocarbons. An excellent temperature range from -20°C to +230°C and high mechanical values rank this synthetic rubber well above conventional synthesis rubbers. Similarly, the very low gas permeability and outstanding resistance to ageing with outstanding pressure deformation make fluorine elastomers ideal.

The outstanding characteristic of acrylate rubber is its excellent resistance to heat and hot oils. ACM is resistant to engine oils containing modern additives, transmission oils, greases etc. In addition, there is the high oxidation, ageing and ozone stability of a well-structured polymer chain.Temperature range from -30°C to +150°C.

Natural rubber is a highly-elastic material with very good physical characteristics, excellent mechanical firmness and very good resistance to low temperatures. Despite the many other synthetic rubbersavailable, natural rubber with its special features still has many important areas of application e.g. for suspensions, machine stocks, rubber metal connections. Temperature range -50°C to +90°C.

Seals made from EPDM demonstrate very good ozone, ageing and weather stability. This rubber is also very suitable where it is required that the assigned seal has a high degree of stability in respect of hot water and steam. Resistance to cold is good, compared with the usual synthetic rubber types.. EPDM’s behaviour in respect of oils, greases and solvents is roughly equivalent to that of butadiene styrene rubber (SBR). Chemical resistance, also with regard to oxidizing working agents, is very good. Can be easily integrated in aliphatic, aromatic and chlorinated hydrocarbons. Temperature range from -40°C to +150°C.

Aflas belongs to by-oxidically interlaced TFE elastomers and to the new generations of fluorine elastomers. Aflas’ sealing elements show unusually good stability in relation to a multiplicity of specific media and chemicals e.g. hot water, water vapour, acids, caustic solutions, ammonia, bleach, sour gases (H2S) and oils as well as amines, in particular media with amine additives and corrosion inhibitors, engine and transmission oils, brake fluids and oxidized alloyed media. The application temperatures are similar to those used for fluorine elastomers, namely -30°C to +200°C (constant temperature).

The chemical and physical characteristics of this rubber are approximately the same as NBR’s. Good resistance to ageing, weather, ozone, refrigerants and acids and alkalis. Temperature range from -40°C to +110°C.
