What are the reasons for the deformation of silicone products in the production of silicone products?

In the production inspection of silicone products manufacturers, the performance testing of semi-finished products is particularly important, so let's popularize the deformation of silicone products. Silicone products belong to the silicone rubber material in synthetic rubber. Its physical properties mainly belong to a kind of solid silicone with strong viscoelasticity. It does not mean that the silicone will never be deformed. If it does not rebound for a long time, it will deform. The main deformation is determined by the material hardness of the silicone rubber product. The softer the material, the smaller the deformation. In industrial equipment, the deformation and resilience of the O-ring is very important. There are quite important reasons. If the stretch rate and deformation are lost, they should be replaced in time to avoid unnecessary situations. The deformation of silicone products is mainly affected by the following situations.

1. Long-term work does not lead to permanent deformation. When used for a long time under high pressure, it is easy to deform for products with relatively hard materials under high pressure.

2. The influence of stretch rate is determined by the hardness and softness of the product. Generally, the stretch rate of silicone rubber can reach up to 300% to 600% (softer material), but excessive stretching during use will directly lead to deformation and deformation. Loss of stretch is permanently deformed, so it should not be stretched excessively during use, regardless of industrial products, daily necessities or silicone jewelry.

3. Affected by temperature, in a humid place, when silicone rubber products are used in humid and high temperature conditions, they will gradually deform during stretching, but with the adaptation and decrease of temperature, silicone rubber products will also appear. Slight deformation. Therefore, whether it is an industrially applied accessory or a sealed product, try not to let the silicone product stretch for a long time unless people think it is.
