What causes silicone products to become "brittle"

With the widespread use of silicone products, various types of silicone products may be used in every corner of life. Although these silicone products may not look eye-catching, they can still play a very important role. However, some silicone products are prone to becoming brittle during use, and once they become brittle, they can no longer be used, which makes many people feel very frustrated. Recently, a customer inquired whether silicone products will become very "brittle" after achieving a hardness of 70-80 degrees. Our answer is: yes! So what are the reasons that can cause silicone products to become brittle? If you want to solve this problem, find the answer from the following article!

The fundamental reason why silicone products become brittle is actually due to the inherent nature of silicone materials. After the hardness of silicone products reaches 60 degrees or above, their tear resistance and elasticity will decrease linearly, resulting in silicone products becoming very brittle! So if you want silicone products to become less brittle, you need to find a way to achieve a hardness below 60 degrees. Of course, there are also some technical production processes that can affect the factors that make silicone brittle.

The following is a production issue. During the production and processing of silicone products, they are heated to a certain temperature. However, if the temperature control is not high or the heating time is too long, it can cause the silicone products to become brittle. In addition, during use and storage, poor ventilation or prolonged secondary vulcanization can also lead to this phenomenon. The most important issue is the material of the silicone products themselves. If the material is not good, it cannot achieve tear strength, so the silicone products will become very fragile.

In addition to these, the brittleness of silicone products is also related to the design of their molds. If the mold design is unreasonable or the production structure is not reasonable, it may lead to the fracturing of the mold during the production process of silicone products. If this phenomenon really occurs, the silicone products produced will naturally become brittle. Therefore, before production and processing, efforts must be made to improve the processing or mold structure. Recommended product: Silicone mold

This is one of the main reasons for the brittleness of silicone products. In addition, if the ambient temperature is too low or the aging phenomenon occurs during use, it can also cause silicone products to become brittle. Therefore, for silicone products, they should be replaced in a timely manner after a period of use if they show signs of aging.
