What are the factors that affect the service life of silicone gasket?

In our daily life, we often hear about the aging problem of products. In the silica gel product industry, silicone rubber products have a longer service life and better performance than other rubber products, but they cannot avoid the destruction of time and environment.Let's look at the factors that affect silicone rubber products.

The service life and aging degree of silicone gasket, more and more attention from consumers, but the silica gel gasket aging, its service life will be affected, if not replaced in time will have a greater impact on the machine and harm.In the mechanical processing industry, the removal and replacement of gaskets is also very troublesome, so how to improve the service life of silicone gasket materials has become a focus of concern.

First of all, we need to understand what factors will directly affect the service life of the silicone gasket, in order to try to avoid aging, prolong the service life of the gasket.

1.The environmental impact

Silicone rubber products will cause local aging due to stress, mostly because of long-term extrusion leading to deformation of silicone rubber and wear or damage in the process of stress.

In the mechanical industry, a silicone rubber accessories may be used for decades, such as the o-ring used in the silicone oil press, belongs to the nature of oil seal, due to long-term stress and friction use, affected by this environment, gasket will be used for a period of time after the performance will be weakened, the life will be reduced.

2. Influence of temperature

Although silicone products than the other materials in terms of high and low temperature resistant performance is good, but the environment of high temperature for a long time to use also can produce very big effect on the silicone gasket, if the silicon raw material hardness is low, back glue materials with low melting point, so in the process of temperature rise, back glue is close to the temperature effect, refer to the plastic flow to get bigger, can lead to dissolve back rubber mold release, but silicone rubber in materials with back glue, they is the key problem of thermal oxidation and heat decomposition caused the decrease of strength of silicone rubber material.

3. The effect of oily liquids

If only used in the water for a long time, silicone rubber products under stationary state for a long time there will be no special effects, its service life can be as much as five to ten years, but in the situation of oily liquid, cannot like rubber, silicone has a very good oil resistant effect, at the same time under the motion state, the density of water density is lower than silicone, silicone rubber gasket stress in water or oily liquid, the silicon chain will reduce by water or oily liquid silicon molecular chain strength, so it is not recommended in the motion state of liquid in use.

4. The impact of materials and manufactured goods

Superiority and inferiority of some raw materials is the most important factor of influence, because different silica gel products factory in the production process used in the formulation of raw materials is different, and the characteristics of raw materials have some differences, because of the different materials of silicone rubber gaskets used in the same place, the same environment in the aspect of the service life is also have very big difference, so in the aspect of material selection and be especially careful performance and detection, etc.

The quality of finished products is very important. In the production and processing of products, the control of time and temperature has a great impact on the softness of finished products and their brittle hardness. The difference in the softness and hardness of finished products will directly lead to the consumption of the service life of product accessories under the influence of stress and other reasons.
