What is the cause of brittle silicone products?

With the widespread use of silica gel products, in every corner of life, it is possible to use a variety of silica gel products.However, some silica gel products are easy to become brittle in the process of use, and then the silicone products can not be used again, so many people feel very headache.Why do silicone products become brittle?

In fact, the fundamental reason for the brittle silica gel products is: the essential reason of silica gel materials. After the hardness of silica gel products exceeds 60 degrees, the anti-tearing and elastic properties of silica gel products will plumb, leading to the brittle silica gel products.So if you want to make silicone products less brittle, you have to find a way to do the hardness below 60 degrees.

In addition, in terms of production, if the temperature control in the processing and production process is not good or the heating time is too long, it will cause the silicone products to become brittle.In addition, in the process of use and storage, cannot maintain good ventilation, or secondary vulcanization time too long can lead to this phenomenon, and the most main is the silicone products of material itself, if the material is bad, will not be able to achieve the tear strength, so the silicone products can easily become very fragile.

In addition to the above reasons, the silica gel products brittle and its mould design also has a certain relationship, if the structure of the mould design is not reasonable or unreasonable, so that it could also lead to the silicone products, in the process of production by fracturing, if appear this kind of phenomenon, produced by the silica gel products will naturally become fragile, so the silicone mold structure design is very important.

The above is the main cause of the silica gel products become fragile, we in use process, if the environment temperature is too low, or is the use of time is too long, the aging phenomenon, also causes the silicone products become fragile, so for the silicone products, products are found in use after a period of time aging phenomenon, should be timely replacement.
