Anti-corrosion Sealing Material

Around the world and across industries, sealing products are critical to safety and efficiency.

Sealing manufacturers in the market generally lack effective solutions for durability and sustainability, But Longsheng did this by leading the transition toward safe, sustainable, high-performance sealing products. Longsheng provides professional service and high-quality products in sealing problems for industries. Our sealing products range including all rotary and stationary occasions.

Types of anti corrosion coatings material

Asbestos Free Gasket

High Pressure Asbestos Gasket

Compressed Asbestos Gasket

Non Asbestos Gasket

Asbestos Gaskets are made of asbestos fiber and rubber as the main raw materials, supplemented by rubber compounds and fillers, and are made by mixing and stirring, hot roll forming, vulcanization, and other processes.

Graphite Products

Graphite Blocks

Graphite Gasket

Packing root products are molded from the coil, are precise in size, can be fixed in density, and do not have any additional fillers or adhesives.

Metal Ring Gasket

Octagon Gasket

Elliptical Gasket

Metal ring gaskets are solid metal gaskets with metal materials processed into octagonal or oval shapes, with radial self-tightening sealing.

Nylon Products

Nylon Plate

Nylon Rod

Nylon Special Shape

Nylon Tube

POM Plate

Nylon products are widely used in electrical and electronic, automobile, construction, office equipment, machinery, aerospace and other industries due to their high-performance advantages in mechanical properties, durability, corrosion resistance, heat resistance, etc., replacing steel with plastic, to replace wood with plastic has become an international trend.

Which Material Are Commonly Used in Anti-corrosion Sealing?

Commonly used gel anti corrosion sealing materials are divided into the following three categories:

1. Fiber and Elastoplastic Materials

There are asbestos, leather, rubber, polytetrafluoroethylene plastics, etc., and it is the main material for manufacturing gaskets, soft fillers, molding fillers, oil seals, and other sealing products. Under the action of low sealing force, large elastic-plastic deformation can be obtained, which has a strong effect on blocking sealing and preventing leakage.

2. Anti-friction and anti-wear materials

There are carbon materials, bearing alloys, cemented carbides, surfacing alloys, engineering ceramics, spraying materials, etc. It has good heat resistance, cold resistance, and high thermal conductivity, and is a friction pair material for manufacturing mechanical seals, piston rings and gap seals, and other dynamic sealing devices.

3. Metal and non-metal materials

There are non-ferrous metals, ferrous metals, hard alloys, precious metals, etc., which are used to manufacture other parts other than friction pairs in sealing products.

Categories of Anti-corrosion Sealing Materials

Anti-corrosion sealing material is divided into two kinds, one is static sealing material, mainly gasket sealing or sealant. There is also direct contact with three categories, which can be divided according to pressure, there is high pressure and medium and low pressure. If it is medium and low pressure, it will choose some soft material and large-width gaskets. If you choose a high-pressure type, generally choose a slightly harder texture and a slightly narrower width of the metal gasket.
