In many silicone products which are often in the course of the use of deformation, such as the common silicone seal ring, for example, some long-term sticky adhesive products and metal compression extrusion, through the frequent force caused by silicone seal ring does not rebound, Non-force phenomenon, some of the long-term use of seals in harsh environments, such as oxygen, heat, light caused by the aging phenomenon caused by disguised, so the initial use of silicone sealing ring for the environment and time, etc. need to consider the material and whether the product Able to maintain long-term life, stretch is not affected and so on.
In the use of the process, a variety of high and low temperature is a major factor affecting the product, although the silicone material to accept more than 200 degrees to -40 degrees of high temperature, but long-term for hot heat conditions will accelerate the aging of the silicone seal ring, The higher the deformation of the product, the greater the deformation of the silicone material is greater than 40% of the total loss of work performance, resulting in leakage of the seal and other reasons. In the case of low temperature can be used to increase the appropriate increase in the amount of compression and tension, in the case of low temperature need to pay attention to product necrosis and deformation of the phenomenon of fracture.
Siliocne seal ring tensile is one of the main operating capacity, so the production of silicone products manufacturers will choose the corresponding tensile strength of the material and the use of various hardness conditions, so long-term repeated use of the demand can choose high tensile silicone material Processing and production to prevent the product over time and affect the performance of the product, because the long-term operation of silicone rubber over the range of the use of the situation often make the product becomes loose, loss of tension, so under sufficient conditions to reduce the work The maximum degree of deformation of the silicone material, so reduce the working pressure is to maintain the best way to seal, in addition to the performance of the product using high-quality materials, high tensile strength and product performance, the higher the product The better the quality.
