Temperature and the tensile strength is how to affect organic silicon seal life
in the organic silicon seal, in long-term glue and metal extrusion process, under the stress of frequent, silicone seal will not rebound, also won't be affected by stress. Some sealing ring has been used in the harsh environment for a long time, such as oxygen, heat, light, etc. , leading to aging. Therefore, the environment and the time of the initial use of silicone rubber sealing ring, whether need to consider the materials and products can keep a long life, does not affect the elasticity and so on.
1. In use process, all kinds of high and low temperature is the main factor affecting the product, can accept 200 to - silicone materials Over 40 degrees high temperatures, but apply to bad heat for a long time can accelerate the aging of silicone seal, the higher the temperature, the greater the deformation of products, the maximum stress of the silicone material deformation usually lost his work performance, cause seal leakage, etc.
in the use of low temperature and should be appropriately increase the compressive strength and tensile strength, the necrosis of the product, and pay attention to the low temperature deformation and fracture phenomenon.
2. Tensile strength is one of the main performance of silicone seal, so in the production of silicone products manufacturer will choose the corresponding tensile strength of the material and the conditions of various hardness, so when the long-term repeated use for a long time, can choose high silica gel materials for processing and production, in order to prevent the product increased with the increase of time influence the performance of the products. For use for a long time outside the scope of tensile products will become loose and loss of tension, so under the condition of sufficient, work intervention will reduce the drawing, use for a long time the biggest factor that affects the silicone material deformation.
so, reduce stress at work is the best way to keep the seal, in addition, the performance of the products using high quality materials, the higher the tensile resistance and hardness of the products, the quality of the product, the better.
