Material selection requirements for rubber seals

Rubber seals are generally used to prevent leakage, so what requirements do we need in terms of material selection?1. Compatibility of the rubber seal material with the working mediumThe material of the seal should be selected according to the sealing medium. There should be good compatibility between the seal material and the working medium, and it should withstand the corrosion and wear of the working medium, and will not have chemical reactions with the working medium to cause precipitation and crystallization.2. Seal material and mechanical speedThe ability of the seal material to adapt to...

Properties and types of rubber seals

Rubber seals are a common and commonly used basic element in sealing devices, and play a very important role in the contradiction between leakage and sealing. And rubber seals are a type of rubber products that are widely used in sealing technology.It is precisely because rubber has a valuable elastic polymer material and a wide temperature range, these two good properties can be given only in different media.

Characteristics and usage of rubber seals

Rubber, plastic, and fiber are named as the three major synthetic materials, and are polymer materials that possess both high stretchability and good elasticity.The great feature of rubber seals is that it has a very small modulus of elasticity, but a very high elongation. And the rubber seal has quite good air permeability and performance to various chemical media and electrical insulation. Some special synthetic rubbers have very good oil resistance and temperature resistance, and can resist the expansion of fatty oil, lubricating oil, hydraulic oil, fuel oil and solvent oil solution, and it...
