20-90 Shore Heat Proof O Rings High Temperature Silicone O Rings

O-ring is suitable for installation on all kinds of mechanical equipment, in the specified temperature, pressure, and different liquid and gas media, in the state of static or moving sealing.

In machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, engineering machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery, and all kinds of instruments and meters, a large number of applications of various types of sealing components.

O - ring is mainly used for static seal and reciprocating motion seal. For rotary motion seal, limited to low speed rotary seal device. O-type sealing ring is generally installed in the outer circle or the inner circle on the rectangular section of the groove to seal.

O ring in oil, acid and alkali, wear, chemical erosion and other environments still play a good sealing, shock absorption role. Therefore, O-ring is the most widely used seal in hydraulic and pneumatic transmission system.

Silicone:The term silicone covers a large group of materials in which vinyl-methyl-silicone (VMQ) is often the central ingredient. Silicone elastomers as a group have relatively low tensile strength, poor tear and wear resistance. However, they have many useful properties as well. Silicone has a good heat resistance, good cold flexibility, and good ozone and weather resistance as well as good insulating and physiologically neutral properties.

Silicone advantage:

1, Excellent heat resistance
2, Excellent weathering resistance
3, Excellent ozone resistance
4, Excellent low temperature, suitable for high and low temperature environment
5, Resistant to alcohol

Silicone Temperature : - 73 ℃ ~ 230 ℃

Silicone Application : Used in all walks of life, transportation, automobile industry, catering industry, toy industry, maternal and child products, electronic and electrical industry, petrochemical industry, machinery industry, medical industry, sports equipment, lighting, audio, clothing and textile industry, etc

NSF		NSF is specialized in standard setting, product testing and certification services in the fields of public health, safety and environmental protection, and is an authoritative body in the field of public health and safety
KTW		The supplier is required to comply with DVGW (German Gas and Water Association) Regulation W 270 "Propagation of microorganisms on Non-metallic materials". This standard mainly protects drinking water from contamination with biological impurities. All drinking water systems and excipients exported to Europe must be KTW certified. Therefore, if Chinese drinking water systems and excipients are to be exported to European countries, they must pass KTW certification. KTW has been authorized by the World Health Organization (WHO) for the certification of safe drinking water.
WRAS		WRAS(Water Regulations Advisory Scheme) certification refers to the Water Regulation Advisory Scheme. WRAS is the certification of the safety of drinking Water in the UK.
UL		Founded in 1894, UL has become one of the world's leading testing and certification organizations with a complete set of management systems, standard development and product certification procedures.
SGS		SGS certification refers to the service that SGS performs compliance certification on targets according to standards, regulations, customer requirements and other conditions. To carry out relevant certification, we must pass inspection, testing, authentication, certification and other means (SGS certification itself is not a certification, but refers to the certification service of SGS).
