The main raw material for insulating rubber sheets is also rubber, because the insulation properties of rubber cannot be matched by other materials. The high elasticity of rubber makes it difficult to break and has good ductility.　

Insulated rubber sheet is made by processing excellent rubber materials. In order to ensure the performance of the product, our manufacturer is very strict when selecting rubber materials.　

Rubber sealing rings are generally annular covers composed of one or several parts, which can be fixed on equipment to prevent the leakage of lubricating oil and the invasion of other substances.　

Rubber sealing rings are used in many mechanical equipment. Some sealing rings are used at the connection between two mechanical components. If the rubber ring is not installed properly, it will not only affect the stability of the equipment during use, but also cause damage to the rubber ring.　

When calculating the length of O-rings, it is necessary to maintain the consistency of units. Under normal circumstances, millimeters or inches are used as units of length. If the units of the outer diameter and the inner diameter are different, unit conversion is required to ensure the accuracy of the calculation results.　

The specifications and dimensions of O-rings mainly include inner diameter, cross-sectional diameter (also known as wire diameter), inner diameter of the groove, outer diameter of the groove, depth and width of the groove, etc. Here are some common examples of O-ring specifications and dimensions:
