Rubber seals are mainly used to prevent water, oil, dust and other impurities from entering the interior of the machine, so they are widely used in various industries. There are many classifications of rubber materials in seals. The following Haisheng rubber is for everyone. Introduce the classification of rubber materials so that everyone can find a more suitable material when choosing.

1. According to the source and essentials of raw materials

Rubber in rubber seals can be divided into two categories: natural rubber and synthetic rubber. The loss of natural rubber accounts for 1/3, and the loss of synthetic rubber accounts for 2/3.

2. According to the surface shape of the rubber

Rubber in rubber seals can be divided into four categories: solid rubber (also known as dry rubber), milky rubber (latex for short), liquid rubber and powder rubber.

3.According to the performance and use of rubber

In addition to natural rubber, synthetic rubber in rubber seals can be divided into general synthetic rubber, semi-universal synthetic rubber, special synthetic rubber and special synthetic rubber.

Natural rubber has higher elasticity at room temperature, a little plasticity, very good rigidity, small loss of hysteresis, low heat generation during multiple deformations, so its resistance to flexion is also good, and because of its black and white polarity Rubber has good electrical insulation properties.

4.According to the physical form of rubber

Rubber can be divided into hard and soft rubber, raw rubber and compound rubber.

5. In industrial use, rubber can be classified as follows:

One type is divided into heat-resistant and oil-resistant rubber: ordinary rubber, heat-resistant rubber, oil-resistant rubber, weather-resistant rubber, and special chemical-resistant rubber.
