Polycarbonates are plastics that belong to the group of synthetic polymers and to the family of polyesters. Polycarbonates are transparent and non-coloured but they can easily be coloured. The material is characterized by its high stability, impact resistance, stiffness as well as its rigidity. Polycarbonates are widely resistant against atmospheric conditions and radiation. They’re flammable but can easily be extinguished by erasing the source of ignition. Moreover polycarbonates are good isolators. They’re water resistant, resistant against many mineral acids and hydrous solutions of neutral salts and oxidants. Also some other non-polar organic solvents like carbon hydride and many oils and fat do not cause any damage to polycarbonates. However polycarbonates aren’t resistant against chlorinated carbon hydrides, e.g. dichloromethane. It is also instable against hydrous alkaline solutions, amines and ammonia.
PC-ESD is made of transparent, two side coated permanent static dissipative
material. The dissipative property reduces particle attraction and the generation of
electrostatic fields. Complies with EN 61340-5-1 and ANSI/ESD S20.20-1999
is crystal-clear, non-coloured and shows no significant absorption in the visible spectrum. The permeability of ultraviolet radiation allows it to use the products for photochemical reactions. The refraction index is at 1,472 (with 589,3 nm) and the photoelastic constant is B 3,6 10-6 MPa-1. The physical properties are described in norm DIN ISO 3585.

The refraction index is at 1,472 (with 589,3 nm) and the photoelastic constant is B 3,6 10-6 MPa-1. The physical properties are described in norm DIN ISO 3585. Borosilicate glass has a high chemical resistance against alcohols, water and acids and their mixtures, as well as chlorine, iodine, bromine. The interaction of water only has a small effect on the glass. A thin layer of fused quartz is built up which reduces a further attack on the glass.Water resistance (ISO 719); Water classification 1Acid resistance (ISO 1776; Acid classification 1-2Alcali resistance (ISO 695); Alcali classification 2 has a high chemical resistance against alcohols, water and acids and their mixtures, as well as chlorine, iodine, bromine.
