PublisherPE isolation film
PE isolation film is a kind of material that plays an important role in protecting carbon fiber composites, but it is inevitable that some aging phenomena will occur in the use of PE isolation film; Because PE isolation membrane separates the environment from materials, PE isolation membrane will be directly exposed to the influence of various environmental factors in the air. With the passage of time, its structural molecules will change and age.
After the aging of PE isolation film, the surface is generally sticky, gradually hardened, brittle, discolored and spotted.
From the source analysis, the aging phenomenon of PE isolation film lies in the influence of molecular structure and physical state, and the molecular structure of polyethylene is complex, The molecular chain contains short methyl branched chain and long alkyl branched chain (there are about 30 branched chains on about 1000 main carbon molecular chains). In addition, there are double bonds and carbonyls on the polyethylene molecular chain, which are unstable factors. Due to the existence of branched chains and double bonds on the molecular chain, the oxygen absorption rate of polyethylene will be greatly accelerated, especially for products with large surface area of thin films, resulting in the aging of polyethylene.
In order to prolong the service life of PE isolation film, we pay more attention to the improvement of aging resistance in product improvement, so that PE isolation film plays a more and more excellent role in the protection of various products.
Our company is a manufacturer of electronic products and spends a lot on the use of PE isolation film. Therefore, we have always been very cautious about selecting PE isolation film in the market
If the cooperation between enterprises is due to fate, the cooperation with Jiankun new materials is a sincere cooperation; Our company has always been very cautious in the investigation of partners, and detailed market research has always been our standard
Our company is a mechanical equipment processing manufacturer. There has always been a great demand for the use of isolation membrane; Using isolation film to pack protective products is our standard configuration, so when selecting partners, our company has high requirements for product quality.
