Silicone O-ring

Silicone O-rings are mainly used for high temperature resistance (based on actual reports), low temperature resistance, environmental protection, and odorless properties. However, they are generally resistant to oil and wear (based on actual reports) and are commonly used for food diagnosis and treatment, household appliances, and high-temperature static sealing.

1、 Basic parameters

Material: Silicone Rubber (VMQ)

Temperature range: generally -60 ℃~+230 ℃, special can reach -70 ℃~+250 ℃

Common hardness: Shore A 40 °~80 ° (commonly 50 °, 60 °, 70 °)

Colors: Transparent, Red, White, Black, Blue, etc

Features: Odorless toxin detection, good physiological inertia

2、 Advantages

Strong high and low temperature performance

High temperature does not soften, low temperature does not harden, and it is more resistant to cold and hot cycles than ordinary rubber.

Food and pharmaceutical grade Anran

Compliant with FDA and food contact requirements, it can be used for drinking water, bottles, coffee machines, and brewing equipment.

Weather resistance, ozone resistance, aging resistance

Long lifespan in outdoor, UV, and ozone environments.

Good electrical insulation

Suitable for sealing electronic, electrical, and lighting fixtures.

good flexibility

Easy to install, good adaptability to rough surfaces.

3、 Disadvantages

Poor tensile strength, wear resistance (based on actual reports), and tear resistance

Not suitable for sports friction and high-pressure dynamic sealing.

Generally resistant to oil

Not resistant to gasoline, engine oil, and mineral oil, it will swell.

General airtightness

High vacuum and high-pressure gas sealing are not as good as nitrile and fluororubber.

4、 Applicable scenarios

Food machinery: coffee machines, water dispensers, beer equipment, rice cookers

Diagnostic and therapeutic supplies: sealing of diagnostic and therapeutic instruments, silicone tube connectors

Home appliances: electric kettle, oven, lighting fixtures, humidifier

Automobile: ignition system, wire harness sealing, high-temperature non oil circuit parts

Electronic appliances: Waterproof (based on actual reports) connectors, outdoor lighting fixtures, sensor sealing

5、 Not applicable scenario

Fuel, engine oil, lubricating oil system

High pressure hydraulic, dynamic reciprocating seal

Strong solvent, strong acid, strong alkali environment
