The deformation of the silicone seal products what are the important factors?

In many silicone products tend to appear in the process of using deformation conditions, such as common silicone seal, for example, some seal products long-term suppression of extrusion, sticky and metal after stress frequently cause the silicone seal does not rebound, do not force, some seals use for a long time in the bad environment, such as oxygen, heat, light aging occur under the action of result in disguised form, so in the initial stage for the use of silicone seal environment and time, and so on all need to consider the material and the product's life whether can maintain a long-term, elastic is not affected, and so on. In use process, all kinds of high and low temperature is one of the main factors affecting the product, the silicone material is able to take more than 200 degrees to - 40 degrees of high temperature, but long-term is suitable for the bad heat circumstances will accelerate the aging of the silicone seal of, the higher the temperature, the greater the deformation of the product will be, and forced deformation of the largest silicone material is generally above 40% will lost his job performance, cause seal leakage, etc. Under the condition of low temperature using can suggest appropriate to increase the amount of compression and tensile strength, under the condition of low temperature using need to pay attention to product necrosis phenomenon and its deformation phenomenon. Tensile strength is one of the main operation ability the silicone seal, so in the silicone products manufacturers will choose the corresponding tensile strength material and using condition of various hardness, so when the demand for long-term use repeatedly can choose high tensile silica gel material processing production, in case the product as the growth of the time and affect the performance of the product, because of the silicone rubber of long-term operation of beyond tensile tend to make the product when using sagging, loss of tension, so under the condition of sufficient to reduce the work involved in tensile strength, long-term effects when using silicone material deformation of the biggest factors, so that the best way to reduce stress at work is to keep seal, in addition on the performance of the product is made of high quality material, high strength and hardness performance is higher, the quality of the product, the better.
