The last factor that influences the physical properties of nylon and plastics in general, is the working environment from a chemical point of view. In conditions of normal use, nylon offers excellent resistance to chemical agents and is particularly resistant to “foreign” hydrocarbons, ketones and ethers; nevertheless it can still absorb a certain quantity of hydrocarbons and small amounts of water, which could lead to changes in dimensions. Other solvents such as strong mineral acids, metal salts and formic acid strongly attack nylon, even at room temperature. When choosing nylon for applications, it is important to take into account the type of solvent, temperature and stress to establish the precise effect.
