The compatibility between ethyl acetate and plastics is related to many practical application scenarios. Ethyl acetate is a common organic solvent with lively properties. In industry and life, it is often encountered in contact with various plastic products.

Guanfu plastics have a wide variety of categories and different characteristics. Those that are hard and tough, and those that are soft and elastic. When ethyl acetate encounters plastics, the interaction between the two is quite complicated. Some plastics, when encountering ethyl acetate, may appear to be swollen. The molecular structure is affected by ethyl acetate, and the gap increases, causing volume expansion. In this case, the physical properties of plastics, such as strength and toughness, may change.

There are also some plastics that have slightly better compatibility with ethyl acetate. Although there is no obvious swelling, long-term contact may result in subtle changes in the surface, loss of gloss, or minor flaws. This is because the molecules of ethyl acetate gradually seep into the surface of the plastic, disturbing its molecular arrangement.

Fundamentally, the compatibility between ethyl acetate and plastics is influenced by multiple factors. The chemical composition of plastics bears the brunt, and different polymer structures have different tolerances to ethyl acetate. For example, polyethylene and polypropylene plastics, due to their tight molecular chain structure, have weak affinity with ethyl acetate and are relatively resistant to swelling. Some plastics containing polar groups have stronger interactions with ethyl acetate.

Furthermore, environmental factors cannot be ignored. When the temperature increases, the thermal motion of the molecule intensifies, the collision frequency between ethyl acetate and plastic molecules increases, and the interaction is more likely to occur, or the compatibility change is intensified.

Therefore, in practical applications, the compatibility between ethyl acetate and plastics must be carefully considered. When choosing plastics, be sure to carefully check its adaptation to ethyl acetate in order to ensure the stability of the product's performance, prolong its service life, and avoid various drawbacks caused by incompatibility.
