What are the technical requirements for silicone sealing rings?

Some people may not be very familiar with silicone sealing rings, which are mainly used for waterproof sealing and preservation of daily silicone products such as fresh-keeping boxes, rice cookers, water dispensers, lunch boxes, insulated boxes, insulated boxes, water cups, ovens, magnetized cups, coffee pots, etc. Since silicone sealing rings involve our daily needs for food and use, what aspects do we need to consider in terms of technology for silicone sealing rings?

The following are some common technical requirements and tests for silicone sealing rings:

1. Selection of silicone rubber materials:

Silicone rubber sealing rings are usually made of high-temperature vulcanized silicone rubber. The material selection should comply with the environment and requirements of product use, such as high temperature resistance, chemical resistance, etc.

2. Hardness requirements:

The hardness of silicone sealing rings has a significant impact on their performance in sealing applications. Hardness is generally tested through shore hardness to ensure compliance with product design requirements.

3. High temperature resistance:

Due to the common use of silicone rubber sealing rings in high-temperature environments, their high-temperature resistance is crucial. Stability testing at high temperatures is required to ensure that elasticity and sealing are not lost under high temperature conditions.

4. Chemical corrosion resistance:

If the silicone rubber sealing ring will be exposed to chemicals, its corrosion resistance to common chemicals needs to be tested to ensure that it will not be damaged by chemicals.

1. Sealing performance test:

The main function of silicone rubber sealing rings is to provide effective sealing, so sealing performance testing is required to ensure that the expected sealing effect can be achieved in practical applications.

2. Anti aging performance test:

Silicone rubber seal ring needs to have good anti-aging performance to ensure that it will not harden, crack and other phenomena after a long time of use.

3. Climate resistance testing:

Considering that silicone rubber sealing rings may be used under different climatic conditions, climate resistance testing is required to ensure their performance stability in different environments.

Through the above series of tests and technical requirements, silicone rubber sealing rings can ensure stable and reliable sealing performance in various application environments.
