NR – Natural rubber Has very high mechanical qualities such as tear- and tensile strength, and durability. For that reason, this type of rubber is often used for vibration dampers that can endure a heavy load without being exposed to sunlight and oil. The rubber can endure temperatures from -50°C to +80°C.
SBR - Styrene-butadiene rubber Has almost the same mechanical qualities as NR but can endure ozone to a higher extent. This type of rubber is used for shock absorbers, vibration dampers, and for tire production. This rubber can endure temperatures from -25°C to +90°C.
NBR – Nitrile rubber Is highly resistant toward oil, gasoline, and some types of solvent; however, it is not resistant toward ozone. It is often used within the food industry for sealing and gaskets. This rubber can endure temperatures from -15°C to +90°C.
EPDM – Ethylene propylene rubber Is highly resistant toward ozone, acids, and bases; however, it is not resistant toward oil and gasoline. It is used for weather-striping, gaskets for the food industry, and sealing for drinking-water when acids and bases are used for cleaning. This rubber can endure temperatures from -50°C to +130°C.
CR – Chloroprene rubber Is highly resistant toward oil and ozone and can endure flex movements. It can be made fire retardant and, therefore, only comes in black. It is used for gaskets being exposed to sea water, ozone, and oil making it ideal for off-shore use. It can endure temperatures from -20°C to +90°C.
VMQ – Silicone rubber Is highly resistant toward both heat and cold, ozone and chemicals, and has electric insulation value; this makes it a very expensive rubber mixture. This rubber is transparent and is, therefore, often used within the food- and pharmaceutical industry. It can endure temperatures from -50°C to +200°C.
FKM/FPM – Fluorine rubber (Viton) Has brilliant mechanical qualities and is resistant toward both heat and chemicals. This rubber mixture is very expensive and is therefore used for special gaskets being exposed to harsh chemicals and heat. Does not come in white. It can endure temperatures from -15°C to +200°C.
HNBR – Hydrogenated rubber Has the same qualities as NBR but can endure temperatures up to 150°C. In addition, it is more resistant toward chemicals. It is used for sealing and gaskets when dealing with high temperatures, therefore making it an expensive rubber mixture. It can endure between -25°C to +150°C.
IIR – Butyl rubber Has low permeability toward oxygen and nitrogen and is, therefore, used for car- and bicycle tubes. It seems unfunctional until +80°C and can endure temperatures from -40°C to +110°C.
TPU – Thermoplastic polyurethane Has very high mechanical qualities and turns dark when exposed to ozone. Therefore, it has to be dyed beforehand, making it resistant. It is being used for gaskets being exposed to excessive wear. Can endure temperatures between -40°C to 80°C.
TPE – Thermoplastic elastomer Has great mechanical qualities and is resistant towards the cold. It is not resistant toward oil and several types of solvent. It has a low water suffocation and great electrical qualities. It is, therefore, used for flexible, electric cables. It can endure temperatures from -50°C to +70°C.
