Because of its special properties, rubber products can be said to be the most widely used parts and are widely used in all aspects of daily life. From doors and windows, cabinets, refrigerators, microwave ovens, etc., to aerospace, medical, electronics, and construction.
But it is also like people, and it is also afraid of various unsuitable environments. At present, the raw materials of rubber products on the market are mostly natural rubber, styrene butadiene rubber, butadiene rubber, butyl rubber, ethylene propylene rubber, isoprene rubber, etc. Mainly, different types of rubber have different molecular structures and performance characteristics, and different changes will occur under the "catalysis" of hot oxygen.
Theoretically, the internal molecular structure of rubber and rubber products will change during the thermal oxidative aging process, which can be roughly divided into two categories. One is the thermal oxidative aging reaction that mainly degrades the molecular chain, that is, cracking; the other is The thermal oxidative aging reaction, which is dominated by cross-linking between molecular chains, is structuring. Different types of rubber have different thermal oxidative aging phenomena, but they all cause the rubber products to lose their performance early.
It can be said that rubber products occupy an important position in the modern market. After long-term use of rubber products in various environments, its performance will inevitably undergo some changes, leading to cracks in the rubber products, tearing, breaking, etc. that affect people's lives. But generally speaking, rubber products have longer service life and better performance than other materials. Even so, regular maintenance is required. Because rubber parts are used in different environments, some people replace rubber products with substitutes, which changes the environment that rubber products should have, resulting in changes in rubber instincts, so their service life will also change.
