PC (polycarbonate)
PC has a good dimensional stability, great stiffness. It does not change its form in high temperatures, is flavour- and odour-free. It has good electrical insulating properties. The material has furthermore great impact resistance and is self-extinguishing and transparent.
APPLICATION FIELDS: coats, shields, accumulator covers, computer housings, covers, windows, internal linings, in machine construction, machine linings, elements of sewing machines and kitchen tools (robots), plinths of fluorescent lamps, post transport tubes, show window glass, letter patterns, antiburglar windows, viewing windows, technical parts.
