Update:2019-01-05

Gasket (double scale flat gasket,annular flat gasket; is a mechanical seal or rubber seal between two objects) DSH Seal share with you that the gasket is the material used can be paper A sealing member made of a rubber sheet or a copper sheet placed between the two planes to reinforce the seal to prevent fluid leakage between the static sealing surfaces.

Gaskets are widely used in petroleum, chemical, machinery, automotive and other industries. The traditional sealing material of the previous gasket is made of asbestos fiber as the main reinforcing sealing material. The asbestos and cellulose fiber and other sealing fillers are bonded together by the adhesive, using the oldest and most traditional Made of papermaking equipment.

Nowadays, due to the environmental pollution of asbestos and the high harm to human health, in many developed countries, there are strict restrictions on the production, sale and use of asbestos products. At present, the technology of sealing gasket technology for making non-asbestos sealing rubber gaskets in foreign countries has made great progress, and the development of sealing gasket technology in China is also relatively rapid. 

In the preparation process of non-asbestos gasket, the vulcanization process plays a vital role in the performance of the gasket. It is the process link. The effective and reliable process plan is an important guarantee for the performance of the sealing material. DSH Seals always pursued!
