Rubber seals are widely used in the sealing field because of their excellent elasticity and compression resistance, which can effectively prevent the leakage of media; it is precisely because of its wide application, so its use scenarios and application environments are diverse and different. Certainly, these are important reasons for the frequent failure of rubber sealing rings. Fracture is an important phenomenon of failure, and fractures account for more than 80% of the bad. So what are the reasons for the rupture of rubber sealing rings? Below I will briefly introduce it.

1. Overload:

Each material and product has its own safe load, and the rubber sealing ring is no exception; for example, the rated load of the rubber ring is 10N, and the working environment has a force of 20N. It is easy to break when the product is designed; therefore, when designing the product, you must check the relevant information to see how much the product is loaded and whether the product is overloaded. Generally, the load does not exceed 90% of the product, which is relatively high. safe.

2. Material aging:

In many cases, material aging is also an important reason for fracture. Each material has its own life. Long-term use and aging exceed its own life. It will break; products will become hard and brittle when they age, and then stress concentration will occur on the notch to cause fracture. , so the rubber sealing ring on the mechanical product needs to be replaced in time before aging and fracture, so as to avoid safety accidents due to the rupture of the rubber ring.

3. The product is corroded

It is well understood that the product breaks after being corroded. For example, the material of the silicone sealing ring is not oil-resistant. How to use the silicone sealing ring in an oily environment for a long time is easy to be corroded and fractured; there is also chemical corrosion. How can it be easy to break without using fluorine rubber seals in the environment of fluorine rubber? Only fluorine rubber seals have the characteristics of corrosion resistance. Therefore, when selecting materials for products, it is necessary to understand the material characteristics and environmental media. Only the material and the medium used are matched. When the product can play its maximum role.

If the rubber sealing ring on the product breaks, it is mainly for these three reasons, which should be carefully analyzed and improved in time.
