Silicone Rubber ( FDA Grade Compliant - Food & Drug Administration )
Silicone rubbers are a group of synthetic elastomers noted for their
(1) resilience over a very wide temperature range,
(2) outstanding resistance to ozone and weathering, and
(3) excellent electrical properties.
General Working Temperature Range: - 60° C to+ 200° C
Silicon Rubber has great cold flexibility as well as high thermal resistance. It has excellent di-electric properties and very good resistance to attack by oxygen, ozone and sunlight. It has poor strength & tear resistance to mineral oils.
EPDM is ideal for outdoor applications because of its excellent resistance to ozone, oxidants, UV exposure and severe weather conditions.
It is highly recommended for applications where the elastomer will have excessive exposure to the environment.
General Working Temperature Range: - 45° C to +150° C
Other outstanding characteristics of EPDM RUBBER include excellent color stability, heat resistance, and dielectric qualities.
EPDM is not recommended for applications involving petroleum derivatives.
EPDM is generally attacked by mineral oils, solvents, and aromatic hydrocarbons.
Nitrile, Buna N, or NBR is the most widely used elastomer in the seal industry. The popularity of nitrile is due to its excellent resistance to petroleum products and its ability to be compounded for service over a temperature range of - 35°C to +120°C .
Nitrile is a copolymer of butadiene and acrylonitrile. it has excellent resistance to mineral oil, greases, water, hydrocarban fuels, compression set resistance and good elastic properties, it is not suitable to automotive brakes fluid.
Viton ( FKM ) , the material is resistant to extreme conditions, including all aliphatic, aromatic and halogenated hydrocarbons, acids, animal and vegetable oils.
General Working Temperature Range: - 20° C to +300° C

One of the most important components of an O ring material is the elastomer material being used. When determining what elastomer is best suited for the environmental conditions in which the seal will be placed, the following properties are important to consider:
* Good elasticity
* High resistance to water
* Good resistance to heat and low temperature
* Good resistance to ozone (UV) and weather aging
* Low compression set
