Aging life is a serious damage to silicone seals. All silicone products suitable for sealing have this defect. For example, our common mechanical doors and Windows, electronic product seals and automobile waterproof seals all have certain defects. Whether silicone, rubber or other materials are chosen, they will gradually lose their function after environmental damage and time testing, and they will not be able to obtain practical results and thus cannot demonstrate the function of the product.

There are many main reasons affecting the service life of silica gel seals, but the silica gel ring will be affected by several common phenomena in any seal.

Due to the size of the force or permanent compression, the installation should be carried out in different ways, such as mounting method, flat surface, groove or groove. The installation method is different for each product. Deviation of force center may result from uneven force distribution. Permanent compression deformation may occur when too much force is applied for a long time. The silicone rings can deform when removed again, so it is necessary to control balance and stress levels in order to integrate evenly during installation.

Product size error leads to clearance deformation:

The gap between kunshan silica gel manufacturers can be divided into several factors. Due to the rubber material of the material, many silicone materials have poor resilience due to formulation, and the problem of inadequate tension causes leakage due to small stresses during use. Processing problems for silicone ring manufacturers include, for example, a tendency to crimp relatively thin products due to their fragility, and cracks due to deformation of soft products after prolonged stretching and compression.

Soft or fragile products may cause failure. Most of the time, it is not the structure of the material and the product, but the quality standard of the product that is affected during the production and processing of silicone rubber products. For example, the hard and soft requirements of the product cannot be understood during processing because the processing time is prolonged, the product is too brittle and cracks appear during installation, or the product is softened due to the need to improve processing efficiency, resulting in deformation of the product under pressure.

Soft and hard effects. In many cases, the function and structure of silicone rubber products can be completely changed according to their different softness. Therefore, in the use of silicone rubber seals, due to different soft and hard stress, tension, extrusion and other phenomena, there will be some inevitable problems in the sealing ring, such as extrusion clearance, excessive stress, high hardness and no product deformation rebound.
