High elastic polymer compounds. It can be divided into natural rubber and synthetic rubber. Natural rubber is made from rubber tree, rubber grass and other plants after extracting gum, while synthetic rubber is obtained from various monomers through polymerization. Rubber products are widely used in industry and life.

Rubber seals are a kind of general basic components in sealing devices, which play an important role in the contradiction between leakage and sealing. In the process of human conquest of nature, leaks and seals are solved. It has been an important way to promote technological progress, prevent and reduce environmental pollution. Rubber seals are a kind of rubber products widely used in sealing technology. Because rubber has precious elastic macromolecule material, a wide temperature range, in different media to give smaller stress will produce greater deformation, this deformation can provide contact pressure, compensate for leakage gap, achieve the purpose of sealing.

The main products of rubber seals are rubber seals, rubber gaskets, flange gaskets, rubber shock absorbers, rubber O-rings, V-rings, X-rings, Y-rings, and other rubber products in various forms, sizes, colors, hardness and materials, rubber strips, rubber rows, rubber plates, O-rings, rectangular rings, beads, diamond beads, squares. Gaskets, oil gauge gaskets, double sealing rings, flanges, boxes, methylene blue, gaskets, flat O, rubber drums, continuous rectangular boxes, etc.
