Material properties of Concentric reducer rubber joint

The material of the Concentric reducer rubber joint has good elasticity, wear resistance, aging resistance and tear resistance, adaptability to deformation, good waterproof performance, and the temperature range is -45°C-+60°C. The concentric rubber soft joint with different diameters is a kind of flexible connector for metal pipes. Concentric rubber soft joints with different diameters mainly have good elasticity, large displacement, easy installation, balance pipeline deviation, etc., and can mainly produce axial, lateral and angular displacement during installation.

The natural rubber of Concentric reducer rubber joint is a highly elastic solid processed from plant sap latex; it has good elasticity, wear resistance, and good mechanical properties; it has excellent physical and mechanical properties, elasticity and processing properties. The disadvantages are poor oxygen and ozone resistance, easy aging and deterioration; poor oil and solvent resistance, low acid and alkali corrosion resistance; low heat resistance. Main application areas: chemical industry, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, plumbing, fire protection and other areas.

Concentric reducer rubber joint's nitrile rubber is particularly resistant to gasoline and aliphatic hydrocarbon oils, second only to polysulfide rubber, acrylate and fluororubber, and better than other general-purpose rubbers. Good heat resistance, good air tightness, wear resistance and water resistance, etc., excellent adhesion. The chemical and physical properties of nitrile rubber change with the change of cyano group content in the polymer, but nitrile rubber always maintains the characteristics of resistance to the dissolution and corrosion of oil, gasoline and other solvents. The higher the cyano group content in the polymer, the more corrosion resistant it is and the less elastic it is. Therefore, the rubber joints produced by nitrile rubber also have the properties of nitrile rubber. We sometimes call the nitrile rubber joints corrosion-resistant rubber joints. The disadvantages are poor cold resistance and ozone resistance, low strength and elasticity, poor acid resistance, poor electrical insulation, and poor solvent resistance.
