Crosslinked polymers are materials formed by connecting individual polymer chains through chemical bonds. This process creates a three-dimensional network that enhances the strength and stability of the material. Common examples include rubber and certain types of plastics, which exhibit improved durability and resistance to heat and chemicals. The crosslinking can occur through various methods, such as heat, radiation, or chemical agents. This modification allows crosslinked polymers to maintain their shape and resist deformation under stress, making them suitable for applications in automotive parts, medical devices, and adhesives. Their unique properties make them essential in many industries.
