Problems solved by technology

However, some halogen flame retardants have harmful substances to the environment and human health, especially during the combustion process.
The addition of phosphorus-based flame retardants to polycarbonate seriously reduces the physical properties of the material, and the flame retardant performance cannot reach the UL94-VO level.
