Tough, optically transparent, break-resistant, Lexan polycarbonate surpasses all other thermoplastics for glazing use, safety and strength. Polycarbonate is a non-toxic polycarbonate thermo resin. The liquid polymer forms when bisphenol A reacts with carbonyl chloride. Uncoated sheets are then heat- or cold-formed. To really understand the superiority of this thermoplastic, consider these products made from polycarbonate: helmets, face shields, airplane and ship portholes, instrument components and electrical insulators – too name just a few. It’s the choice for safety, thermal protection, security, clarity and strength. Standard polycarbonate sheets even have built-in forced entry protection.
