Huge NBR FKM HNBR machinery sealing Step molding big size O ring
Description:
NBR Nitrile Rubber Sealing Ring:
Suitable for use in petroleum-based hydraulic oil, glycol-based hydraulic oil, diester-based lubricants,
gasoline, water, silicone grease, silicone oil and other media. It is the most versatile and lowest cost rubber seal.
Not suitable for polar solvents such as ketones, ozone, nitro hydrocarbons, MEK and chloroform.
The general temperature range is -40~120 ℃.
HNBR hydrogenated nitrile rubber sealing ring:
It has excellent corrosion resistance, tear resistance and compression deformation resistance,
and has good resistance to ozone, sunlight and weather. It has better abrasion resistance than nitrile rubber.
It is suitable for washing machinery, automobile engine system and refrigeration system
using new environmentally friendly refrigerant R134a. It is not recommended to use in alcohols,
esters or aromatic solutions. The general operating temperature range is -40~150 ℃.
SIL silicone rubber sealing ring: It has excellent heat resistance, cold resistance,
ozone resistance, and atmospheric aging resistance. Has good insulation properties.
However, the tensile strength is worse than that of general rubber and has no oil resistance.
Suitable for household appliances such as electric water heaters, electric irons, microwave ovens, etc.
It is also suitable for all kinds of articles that are in contact with the human body, such as kettles, drinking fountains, etc.
It is not recommended to use in most concentrated solvents, oils, concentrated acids and sodium hydroxide.
The general operating temperature range is -55~250 ℃.
FKM fluorine rubber sealing ring: The high temperature resistance is better than that of silicone rubber.
It has excellent weather resistance, ozone resistance and chemical resistance, but poor cold resistance.
It is resistant to most oils and solvents, especially acids, aliphatic hydrocarbons, aromatic hydrocarbons
and animal and vegetable oils. It is suitable for the sealing requirements of diesel engines,
fuel systems and chemical plants. Not recommended for use in ketones,
low molecular weight esters and nitrate-containing mixtures. The general use temperature range is -20~250 ℃
FLS fluorosilicone rubber sealing ring: Its performance has the advantages of fluorocarbon rubber and silicone rubber,
and it has good resistance to oil, solvent, fuel oil and high and low temperature.
It can resist the erosion of oxygen-containing compounds, aromatic hydrocarbon-containing solvents
and chlorine-containing solvents. Generally used for aviation, aerospace and military purposes.
It is not recommended to expose to ketones and brake fluid. The general use temperature range is -50~200 ℃.
EPDM rubber seal ring: It has good weather resistance, ozone resistance,
water resistance and chemical resistance. It can be used for alcohols and ketones,
and can also be used for sealing in high temperature water vapor environment.
Suitable for sanitary ware, car radiator and car brake system.
Not recommended for food use or exposure to mineral oil. The general use temperature range is -55~150 ℃.
PU polyurethane rubber sealing ring: The mechanical properties of polyurethane rubber are very good,
and their wear resistance and high pressure resistance are far better than other rubbers.
The aging resistance, ozone resistance and oil resistance are also quite good,
but it is easy to hydrolyze at high temperature. Generally used in high pressure and wear resistant sealing links,
such as hydraulic cylinders. The general use temperature range is -45~90 ℃
O-rings are often used for mechanical seals. Since most O-rings are compression molded,
the process of segmented vulcanization is often used to make seals in mechanical equipment.
Can be customized according to drawings and samples.
