Ge Mao Rubber Industrial Co., Ltd is a manufacturer of o-rings and gasket seals since 1981
Nitrile o-rings and seals are commonly used in hydraulic seals and pneumatic seals because of its superior resistance to wear and abrasion. As such, nitrile is the standard compound specified for such uses. However, nitrile or nbr may not be suitable or compatible with direct sunlight exposure and the ability of nitrile to resist the degradation effects of ozone and sunlight is limited.
Hydrogenated form of Nitrile known as HNBR is a formulation that addresses these shortfalls. Enhance formulations can enable nitrile to have added properties in terms of chemical and physical abilities. Nitrile is extensively specified as a material for use in many applications over a wide range of industries because of its relatively low cost and desirable mechanical properties.
Typical properties of Nitrile o-rings and seals include:
Nitrile is not compatible with:
