With the development of technology, organic silicon materials have been popularized in different industry fields, and sealing rings are one of them. Currently, in many electronic products and daily necessities, sealing materials cannot be separated. Silicone and rubber materials are the preferred standards among soft adhesives, which not only determine the sealing function of the product but also control the quality of the entire product. Therefore, there are certain standard requirements for small sealing rings, So it is difficult to determine the difference between silicone sealing rings and rubber ring materials. How do you choose silicone or rubber materials to make sealing rings?

With the development of different industries and product updates, silicone sealing products and rubber sealing rings have always been commonly used materials in many of our materials. Their performance and function are basically the same, but there are still some differences in details:

Silicone sealing ring: Silicone material is an environmentally friendly and safe material, mainly used in daily necessities and home appliances. Many people choose silicone material to make sealing rings in places where there is a lot of contact with the human body. Moreover, its performance in soft rebound and environmentally friendly odor is outstanding. Under the same conditions, its waterproof and dustproof functions and material usage conditions can meet various product categories, The product features are as follows:

Silicone product characteristics:

1. Safe, environmentally friendly, non-toxic, and environmentally friendly for long-term contact with skin

2. Has good resistance to high and low temperatures, with a temperature range of -40-260 degrees Celsius

3. Good stretching and rebound effect, high stretching rate, and rebound rate up to 80-350%

4. It can be heated at high temperature without deformation and harmful substances. It remains yellow and does not fade after long-term use

5. Corona resistance, arc resistance, high and low temperature resistance, good aging resistance, high temperature resistance, and compliance with import and export environmental standards.

6. Can be customized with any color and various soft and hard hardness, with no color limitations. Different soft and hard hardness can be blended to match the performance of the product

Rubber sealing ring: Rubber sealing ring mainly focuses on performance and is currently widely used in mechanical equipment and some outdoor harsh environmental conditions. Due to the fact that rubber materials can be adjusted to different properties, there are only a few conventional materials: fluorine rubber, nitrile rubber, ethylene propylene rubber, natural rubber, chloroprene rubber, and other materials, so the category of rubber occupies a relatively wide range, You can adjust the performance of different rubber materials according to your requirements, and the difference between it and silicone materials is that they have stronger corrosion resistance than silicone materials. However, the product's appearance and environmental friendliness are relatively weak, and it is mostly used in places with less contact with the human body.

Rubber product characteristics:

1. It has good temperature resistance and corrosion resistance, and does not react with concentrated acids, alkalis, or strong oxidizing agents at high temperatures

2. The product has good wear resistance and flexibility performance, with excellent oil resistance, solvent resistance, chemical media, aromatic solvents, and other properties

3. Resistant to fuel oil, high temperature, Freon, superheated water, steam, and excellent chemical corrosion resistance

4. It has good weather and ozone aging resistance, non-toxic, anti adhesive, as well as good elasticity and sealing properties

5. Can be used for oil seal environments in multiple industries such as industrial equipment, petrochemical, aerospace, military, and more

With the update and development of products, more and more rubber seals are being replaced by silicone seals. Therefore, the most important choice for choosing silicone is to choose the functional usage environment. With the changes in the performance and characteristics of silicone products, currently, water-based seals mostly choose silicone environmentally friendly materials as sealing rings, while rubber materials are mostly used in oily sealing environments.
