Dichloracetic Acid, also known as DCA, is an organic compound commonly used as a disinfectant, a preservative, and a reagent in various chemical processes. Common industries that use this chemical include medical, pharmaceutical, and food packaging.
When rubber is exposed to dichloracetic acid, it can cause swelling and embrittlement of the rubber. This is due to the low molecular weight of the chemical, which causes the rubber to become soft and pliable. Additionally, dichloracetic acid can cause corrosion of the rubber, as well as discoloration and cracking. It is important to choose the right rubber material for any application that requires exposure to this chemical in order to minimize potential damage.
