What should be noted when selecting the material of silicone rubber sealing accessories?
The main function of silicone rubber sealing accessories is to seal, and there are many sealing media, mainly oil. It plays a role in dust and oil isolation in application. The performance of silicone rubber sealing accessories directly affects the performance of other equipment, and the material is the first to determine the performance of silicone rubber sealing accessories. So how to choose the material of the sealing ring? What factors are related to it? Today, the manufacturer will give you a specific introduction.
1. Mechanical motion speed. The material of silicone rubber sealing accessories has different adaptability to mechanical motion speed. Some ordinary materials cannot adapt to high-speed mechanical operation. Therefore, when selecting the material of silicone rubber sealing accessories, it is necessary to choose higher end ones in order to use high-speed operation.
2. Media compatibility. This plays a very important role in the selection of materials for silicone rubber sealing accessories. Some silicone rubber sealing accessory materials may come into direct contact with the medium. If the compatibility between the two is not good, it may cause damage to the silicone rubber sealing accessories or even contaminate the medium. In addition, the material of silicone rubber sealing accessories cannot be corroded or undergo chemical reactions with the medium, which is also a special reminder from the manufacturer.
3. Pressure. The material of silicone rubber sealing accessories also affects the working pressure. Different materials can withstand different pressures. If the medium is oil, it can withstand less pressure. If the pressure exceeds the material's bearing range, it will reduce the service life of silicone rubber sealing accessories. You can choose according to the manufacturer's advice.
When choosing the material of silicone rubber sealing accessories, in addition to paying attention to movement speed, pressure, and medium compatibility, temperature should also be taken into account. Temperature also has a certain impact on the material of silicone rubber sealing accessories. Either too high or too low temperature is not acceptable. If the temperature is too high, it will reduce the tensile strength and hardness of silicone rubber sealing accessories. If the temperature is too low, it will make silicone rubber sealing accessories very brittle. Each type of silicone rubber sealing accessory material has its own suitable temperature range, which should also be noted. Therefore, when choosing the material of silicone rubber sealing accessories, everyone must consider comprehensively. If it is difficult to choose for oneself, you can consult Guangdong Yingtai High Precision Technology Co., Ltd.
