Why do silicone products often become brittle?

In fact, the root cause of the brittle silicone products is: the essence of the silicone material, in the silicone products to the hardness of more than 60 degrees, its tear resistance and elasticity will be straight down, resulting in the silicone products become very brittle! Therefore, if you want silicone products to become not so brittle, you will find a way to do below the hardness of 60 degrees. Of course, some technical production processes can affect the factors of silica gel embrittlement.

This is one of the main reasons leading to brittle silicone products, in addition to the use of the process, if the ambient temperature is too low, or the use of time is too long, there has been aging phenomenon, the same will lead to brittle silicone products, so for silicone products, after the use of a period of time to see the product aging should be replaced in a timely manner.
With the widespread use of silicone products, in every corner of life, it is possible to use a variety of silicone products. Although these silicone products look inconspicuous, but can also play a very important role, but some silicone products in the process of use is easy to become brittle, brittle after the silicone products can no longer be used, so many people feel very headache. Recently, many customers have consulted whether silica gel products will become "brittle" after hardness of 70-80 degrees. Our answer is: yes! So what are the reasons for the brittle silicone products?
The following is the production problem. In the process of production and processing of silicone products, it will be heated to a certain temperature. However, if the temperature control is not high or the heating time is too long, the silicone products will become brittle. In addition, in the process of use and storage, good ventilation cannot be maintained, or the secondary vulcanization time is too long, which will also lead to this phenomenon, the most important thing is the material problem of the silicone product itself. If the material is not good, the tear strength cannot be achieved, so the silicone product will become very fragile.
In addition to these, the embrittlement of silicone products is also related to the design of the mold. If the mold design is unreasonable or the production structure is unreasonable, it may lead to silicone products. During the production process, the mold is fractured. If this phenomenon really occurs, the produced silicone products will naturally become brittle. Therefore, before production and processing, it is necessary to try to improve the processing or mold structure.
