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.
Machine grade polycarbonate exhibits superior impact strength and rigidity over a wide range of service temperatures and is often used for structural applications where transparency and impact strength are essential. Machine grade polycarbonate is stress relieved, making it ideal for close tolerance machined parts.
Clear, standard, and custom colors are available in coated or laminated stock.
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. Contact an Emco Industrial Plastics representative who can help you choose the correct material to meet the needs of your applications.
