Chemical resistance refers to the ability of a material to withstand exposure to various chemicals without significant degradation or loss of functionality. This property is crucial in industries such as pharmaceuticals, food processing, and chemical manufacturing, where materials often come into contact with corrosive substances. Materials with high chemical resistance can prevent reactions that might lead to rust, corrosion, or other forms of damage. Common examples include plastics like PTFE (Teflon) and polypropylene, which are often used in containers and pipes to safely handle aggressive chemicals.
