Friendly Version
Polycarbonate resin is one of the toughest, most versatile engineering
thermoplastics, combining outstanding electrical insulation properties,
performance history and economic advantages over other thermoplastics,
metals, glass and other materials. Available with a variety of
additive options which enhance UV stabilization, flame and heat
resistance, impact strength, dimensional stability and optical
quality: Polycarbonate resin is widely used in the appliance,
automotive, packaging, electrical and electronic industries.
