Silicone Rubber Ring Seal is very common in life. When you use them, have you ever considered how high temperature resistant the silicone sealing ring is? Also, when choosing a suitable silicone sealing ring, what matters need to pay attention to, let's find out together below.
1. How many degrees of high temperature can the silicone sealing ring withstand?
The highest temperature resistance is generally about 300 degrees. Silicone sealing ring has strong high-temperature resistance and low-temperature resistance. It can not only be used in an environment of minus 60 degrees, but also can be used in an environment of 200 degrees for a long time, and it is generally not easy to deform during use. Phenomenon.
When the ambient temperature is higher than 300 degrees, it can still be used continuously, but the service life will be shorter. Once the ambient temperature exceeds 350 degrees, it is prone to deformation and other phenomena. In addition, its color is relatively bright and rich, it also has good anti-skid and heat insulation properties, and it is not easy to age. At the same time, it also has a certain degree of elasticity and softness.
It is widely used as a sealing material for lunch boxes, fresh-keeping boxes, rice cookers, and other products.
2. What should be paid attention to when purchasing silicone sealing rings
① There are many specifications and models of silicone sealing rings on the market. The specifications and models are different, and their performance, scope of use, size, price, etc. will also be different. When purchasing, you should consider the actual use environment and the pressure of the sealing position. , ambient temperature, working hours, etc.
②When purchasing, you also need to know the hardness of the silicone sealing ring, because the silicone sealing ring is generally used as a sealing material, and the sealing position will generally generate pressure, causing the silicone sealing ring to be compressed. If the hardness is insufficient, there will be a large gap in the sealing seat, resulting in a poor sealing effect.
