The choice of  seal material  is of great significance to its sealing performance and service life. The performance of the material directly affects the performance of the seal. The  sealing ring with sealing  performance should have the following characteristics: (1) Flexible and resilient; (2) Appropriate mechanical strength, including expansion strength, elongation and tear strength. (3) The performance is stable, it is not easy to swell in the medium, and the heat shrinkage effect (Joule effect) is small. (4) It is easy to process and shape, and can maintain precise dimensions. (5) Does not corrode the contact surface and does not pollute the medium. The most suitable and most commonly used material to meet the above requirements is rubber, so most of the sealing ring is made of rubber material. The following are commonly used materials for sealing rings: NBR, HNBR, SIL, EPDM, CR, NR, FKM, etc. Cotact Information:Jency Xu LinkIn/Facebook/...

Top Grade soda ash sodium carbonate Soda ash   is one of the most  important chemical raw materials and is widely used in chemical, glass, metallurgy, paper making, printing & dyeing, synthetic detergent, petrochemical, foodstuff,medicine & sanitation industries, etc. With a large consumption, it occupies a crucial place in national economy. CAS No.:497-19-8 Other Names:  Sodium carbonate anhydrous; Sodium carbonate solution; soda ash; disodium carbonate; Sodium carbonate-12C, 13C-depleted; calcined soda; Carbonic acid disodium salt; Sodium carbonate,high-purity; Sodium carbonate,dense; SODA ASH LIGHT MF:Na2CO3 EINECS No.: 207-838-8 Grade Standard: Industrial Grade Purity: 99%   Soda ash  use: 1.The manufacture of glass is one of the most important uses of sodium carbonate. When it is combined with silica (SiO2) and calcium carbonate (CaCO3) and heated to very high temperatures, then cooled very rapidly, glass is produced. This type o...
