High elastic polymer compound. It is divided into natural rubber and synthetic rubber. Natural rubber is made from gum extracted from rubber trees, rubber grass and other plants; Synthetic rubber is obtained by polymerization of various monomers. Rubber products are widely used in industry or all aspects of life.

Rubber seals It is a kind of general basic element in the sealing device and plays a very important role in the contradiction between leakage and sealing. Solve leakage and sealing problems in the process of human conquest of nature. It has always been an important way to promote technological progress and prevent and reduce environmental pollution. Rubber seals are a kind of rubber products widely used in sealing technology. Because rubber is a precious elastic macromolecular material, with a wide temperature range, it will produce large deformation if given a small stress in different media. This deformation can provide contact pressure, compensate leakage gap, and achieve the purpose of sealing.

The rubber seal is made of metal rubber, which is a homogeneous elastic porous material. It not only has the elasticity of rubber, but also has the excellent characteristics of metal, and can work at - 150~800 ℃. At the same time, it can also bear pressure, and has dual functions of bearing pressure and sealing within a certain range. Its uses mainly include the following:

1. FRP pipe; FRP sand pipe; FRP pipe jacking; Cable protection pipe; Flue gas desulfurization pipe; Coal mine gas drainage pipe; Desulfurization and dust removal pipe of power plant;

2. Sealing of municipal water supply and drainage pipeline;

3. Sealing of various process pipelines;

4. Sewage collection and transmission pipeline, reclaimed water pipeline sealing;

5. Sealing of drinking water transmission trunk pipe and distribution pipe;

6. Oil field water injection pipe sealing.
