Customized FDA Flat Neoprene Silicone Rubber O Rings

Neoprene Washers, also called Neoprene Gasket, Neoprene Sheet, CR Seal & CR Gasket, which is mainly made by rubber compression mold tooling for Oil Sealing Washer.

Neoprene Gasket, is a kind of machinery, equipment, pipe for the sealing parts, as long as there is a fluid place usually need to use the sealing parts.Rubber seal gasket is made of rubber plate material by cutting, stamping or cutting, which is used for sealing connection between pipes and between parts of machine and equipment.

Neoprene Washers have good physical properties, oil proof, heat & flame resistance, sunlight resistance, ozone resistance, acid & alkali resistance and anti chemical. However, cold tolerance and storage stability is not good.

Neoprene Washers have a good tensile strength, elongation crystalline and adhesion.

Neoprene Washers good performance, high service life, dynamic pressure seal service life is 5-10 times higher than the conventional rubber seal products, up to tens of times, in some conditions can be with the seal matrix life.

Rubber seal gasket friction resistance is small, static and static friction is equal, is "0" rubber ring friction 1/2 -- 1/4, can eliminate low speed, low pressure under the movement of the "crawling" phenomenon.

Rubber gasket high wear resistance, sealing surface after wear with automatic elastic compensation function.

Rubber gasket good self - lubricating performance, can be oil - free lubrication seal.

Working pressure of rubber gasket :0-300MPa;Operating speed15m/s;Operating temperature :-55 -- 250℃.

Rubber gasket suitable medium: hydraulic oil. Gas. Water. Mud. Crude oil. Emulsion. Water - ethylene glycol. Acid. Alkali. Chemicals.

Rubber gasket structure is simple, easy to install.

CR Seals (Neoprene Seals) are excellent in aging resistance, heat & oil resistance and chemical resistance

Neoprene Washers &Gaskets, which have good weather resistance, ozone resistance and aging resistance, ranks only second to EPR Gasket and II R ( Isobutylene Isoprene Rubber )

Oil resistance ranks only second to that of NBR.

Heat resistance is equal to that of NBR materials.

Neoprene Washers' decomposing temperature is 230～260℃, working in 120～150℃ for a short period and 80～100℃ for a long time, with a certain flame resistance. Inorganic acid and alkali resistance is good. Cold tolerance and insulation are poor.

Gasket sealing structure is widely used in all kinds of machines and equipment, especially in all kinds of pressure vessels, pipes and valves.The simplest gasket for the flat gasket, the entire gasket is composed of the same material, as a mechanical equipment in general joint surface static seal, such as the speed reducer seal.
