The table shows a guideline of the most properties of the rubber applied to tests out at room temperature (23° C).



- Nitrile butadiene ( NBR ).
Is a copolymer of acrylonitrile and butadiene, and it is available in various ratios of these monomers. Better Known as nitriles, reinforced NBR rubbers have good oil and gasoline resistance, tensile strength, elongation properties, heat resistance and low compression set. Special compounding is required for good weather ability. Typical applications for these medium priced tubers are seal, O-rings, gaskets, diaphragms, pipe gaskets, tank linings, boots and bellows.



- Ethylene propylene (EPR and EPDM).
Is produced in two types: a fully saturated copolymer of ethylene and propylene (EPR) and an unsaturated version of ethylene and propylene plus a no conjugated dyne as a third monomer (EPDM). Being unsaturated, the terpolymer is capable of sulfur vulcanization. The copolymer must be, and the terpolymer may be, cured with peroxides also.




- Silicon rubber (SIL).

Silicone rubber offers good resistance to extreme temperatures, being able to operate normally from −55 °C to +300 °C. At the extreme temperatures, the tensile strength, elongation, tear strength and compression set can be far superior to conventional rubbers although still low relative to other materials. Organic rubber has a carbon to carbon backbone which can leave them susceptible to  ozone ,UV ,heat and other ageing factors that silicone rubber can withstand well. This makes it one of the  elastomers of choice in many extreme environments.




- Fluorocarbon (VITON) (FKM).

FKM rubber is a fluoroelastomer most commonly known as Viton. has strong compatibility with a range of chemicals, oils, and heat, making it one of the most common and widely used sealing materials. FKM compounds are widely used in chemical, automotive, aerospace and industrial applications. Viton Characterized Outstanding heat stability, Situational service life above 200°C, Excellent resistance to acids, fuels, mineral and vegetable oils and greases, aliphatic, aromatic and chlorinated hydrocarbons, non-flammable hydraulic fluids (HFD) and many organic solvents and chemicals, Excellent resistance to aging and ozone, low gas permeability and low compression set.





Perfluoroelastomer (FFKM) (Kalrez).
Commonly referred to as Kalrez this expensive elastomer type is usually produced as a terpolymer of tetrafluoroethylene, a cure site monomer used for cross-linking. Due to the complete fluorination of the polymer backbone, these premium material exhibit almost universal chemical resistance. Depending on the compound ingredients employed for cross-linking, these material may also offer the ultimate in heat resistance.
