In recent years, the use of these resins has been controversial: the basis of this controversy is their leaching that, occurring at high temperature, releasesbisphenol A, a compound that is on the list of potential environmental hazardous chemicals. Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Hard and sturdy, it can withstand high temperatures and is found in tupperwares, car parts, thermal vests, yogurt containers, and even disposable diapers.
