Regardless of what kind of material, should have the following properties

Sealing material used at home and abroad are mostly polymer elastomer, there are a number of special conditions, the use of plastic and various metals. But regardless of what kind of material, should have the following properties:1, with some mechanical and physical properties: such as tensile strength, elongation strength, elongation;2, there is a certain degree of flexibility, hardness fit and compression set; 3, the working media, not prone to swelling, decomposition, hardening;4, wear, there are some anti-tear properties; 5, high temperature, low temperature aging.However, there is no sealing materials include all of the above properties, the need to work environment, such as temperature, pressure, media and sport mode to select Hydraulic adapters  suitable sealing material, and through the development of materials with recipe to meet certain requirements. Or the use of composite materials or a combination of two or more structures in the form of play to their strengths, to achieve more comprehensive results.
