What causes the deformation of silicone products?

Silicone products have certain softness and resilience, but why do some silicone products deform and do not rebound when used? For example, if the silicone sealing ring cannot be restored after deformation, the sealing function will be lost. What are the factors that cause the deformation of silicone products?

Silicone rubber products are deformed due to long-term immobility. They are used under high pressure for a long time. Under high pressure, products with relatively hard materials are easy to deform.

Influence of stretching rate: the soft and hardness of products are determined by stretching. However, excessive stretching in the process of use will directly lead to deformation and loss of stretch and then deformation. Therefore, it should not be excessively stretched in the process of use, whether it is industrial products, household products or food grade silicone rubber.

Temperature affected place: a humid place. When the silicone rubber product is working, it will gradually deform during stretching under the condition of humidity and high temperature. However, the silicone rubber product will also slightly deform as the temperature adapts and decreases. Therefore, whether it is accessories or sealing products used in industry, do not let silicone products stretch for a long time unless it is artificially thought.

In various industries, the silicone rubber products with relatively large volume of daily necessities are deformed and do not rebound after deformation. In this way, the long-term deformation will gradually become another shape, which makes it difficult for us to use, especially the silicone rubber pad and products with relatively thin thickness.

The silicone rubber products are not properly maintained during use, which leads to the accelerated aging speed. The silicone rubber products are not dried in cleaning, and the long-term exposure leads to thermal reaction. The application environment is different. For example, the places where ozone is very destructive will lead to the deformation of the silicone rubber products, and the incorrect maintenance method of the silicone rubber products will also lead to the deformation of the products. The correct cleaning and application generally will not cause the deformation. Therefore, it is necessary to pay attention to some details during use.
