The characteristics of polycarbonate are quite like those of polymethyl methacrylate (PMMA; acrylic), but transparency, excellent toughness, thermal stability and a very good dimensional stability make polycarbonate one of the most widely used engineering thermoplastics in applications demanding high performance properties. This amorphous thermoplastic is highly transparent to visible light - it rates highest among transparent, rigid thermoplastics - and has better light transmission characteristics than many kinds of glass.
An alloy formed with those two polymers produces a material with good chemical resistance as well as good heat and impact resistance. The PC contributes impact, stiffness and heat resistance, while the PBT contributes chemical resistance.
A large number of end use applications, i.e.,special grades that provide specific properties or processing characteristics (weatherability,abrasion/ scratch resistance, heat/flame retardance, UV stability, and static dissipation) for polycarbonate are possible by tailoring grades with specific molecular properties and additives during its manufacture.
