Silastic ring SIL: has excellent heat resistance, cold resistance, ozone resistance, resistance to atmospheric aging. It has good insulating properties. However, it has lower tensile strength than ordinary rubber and it is not oil resistance. It is applied to appliances such as electric water heaters, electric irons, microwave ovens and so on, also applied to a variety of body contact supplies, such as kettle, water dispenser. It is not recommended for use in a large part of the condensed solvent, oil, concentrated acid and sodium hydroxide. General use temperature range is -55 ~ 250 ℃.

VITON fluorocarbon rubber seals: better high temperature resistant than the silicone rubber has excellent weather resistance, ozone resistance and chemical resistance, poor cold resistance. It is resistant to most of the oil and solvent resistance, especially acids, aliphatic hydrocarbons, aromatic hydrocarbons, and animal and vegetable oils. Applicable to the sealing needs of diesel engines, fuel systems and chemical plants. Is not recommended for use in ketones, low molecular weight esters and a mixture containing nitrate. The general temperature range is -20 ~ 250 ℃.

CR neoprene seals: resistance to sunlight, weather is particularly good performance. Resistant to dichloro-difluoro methane and ammonia and other refrigerants, dilute acid-resistant, resistant to grease the Department of lubricants, but the expansion of large amount of mineral oil with low aniline point. Easy to crystallize at low temperature hardening. Applicable to a variety of environment and a variety of flame contact with the atmosphere, sunlight, ozone, chemical resistant seal link. Is not recommended for use in the chemicals of the acid, nitro hydrocarbons, esters, chloroform, and ketones. General use temperature range is -55 ~ 120 ℃.
IIR Butyl rubber seals: tightness particularly good heat resistance, resistance to sunlight, good ozone resistance, good insulation properties; polar solvents such as alcohols, ketones, esters, have a good resistance, can be exposed to movingvegetable oil or oxides. Suitable for chemical resistance or vacuum equipment. Is not recommended to use with petroleum solvents, kerosene or aromatics. The general temperature range is -50 ~ 110 ℃.

NR natural rubber seals: with good abrasion resistance, flexibility, tensile strength and elongation. But easy to aging in the air, when heated, variable viscosity, easy expansion and dissolved in mineral oil or gasoline, alkali-resistant but intolerant acid. Suitable for use in hydroxyl ions in automotive brake fluid, ethanol and other liquid. The general temperature range of -20 ~ 100 ℃. 

PU polyurethane rubber seals: mechanical properties of polyurethane rubber is very good, wear-resistant high-pressure performance is far superior to other rubber. Aging resistance, ozone resistance, oil resistance is also quite good, but the high temperature is easily hydrolyzed. Generally used for high pressure resistance, wear-resistant sealing areas, such as hydraulic cylinders. The general use of a temperature range is -45 ~ 90 ℃.
