Rubber Special Shaped Seal Ring

Product Introduction

In the selection of rubber materials for seals, we must consider several important indicators:

I.Consideration of use conditions 1.Objects to be touched (including liquid, gas, solid and various chemical agents) 2.Range of Temperature (lowest and highest temperature) 3.Range of Pressure (Minimum compression ratio of seals under pressure) 4.Static or dynamic using considerations

II.Consideration of design requirements 1.Combination of consideration 2.Consideration of possible chemical reactions in use 3.Consideration of service life and review of possible failure cause 4.Consideration of component lubrication and assembly method 5.Consideration of tolerance

III. Consideration of inspection requirements 1. Define inspection criteria 2. Determine confirmation of the need for sample 3. Set the acceptable criteria 4. Main sealing surface setting

IV. Selection of material specifications 1. Determine the selection of material specifications, such as ASTM, DIN, JIS, etc. 2. Discuss with suppliers. Define the selection of rubber materials. 3. Choose the supplier with good quality and maintain stability of the supplier.

V. Cost considerations Choose suitable materials, in order to avoid improper rubber materials with high cost, resulting that the products can not play the sealing function. Both natural and synthetic rubbers have common rubber properties, such as resilience after compression, flexure resistance, compression resistance and permeability to gas and liquids. Each type of rubber elastomer has its own unique properties. At the same time, the rubber composition can also affect its properties. At present, there are more than 20 kinds of rubber elastomers and they are widely used in all kinds of material needs. In addition, through the professional mixing refinery formula design and mixing, it can provide more in line with the needs of various projects. At the same time, vulcanization transforms rubber from a thermoplastic mixture into a thermosetting shape. Crosslink provides rubber molecular chain strength and elasticity to the performance of seals. Therefore, it is very important for the seal designer to discuss with the sealant builder and the sealant supplier about the materials to be used.
