Polycarbonate ( PC ) - Conductive Polycarbonate - Properties - Supplier Data by Goodfellow

Polycarbonate is produced as a colorless and crystal clear, amorphous engineering thermoplastic. It is known for its high impact resistance (which remains high down to -40 °C), with good dimensional stability and reasonably good temperature resistance.

Polycarbonate is a low creep material, is prone to environmental stress cracking, and has somewhat limited chemical resistance. Also, it has poor wear and fatigue properties.

Background

Conductive polycarbonate (PC) is polycarbonate film filled, typically with carbon, to give a measure of electrical conductivity. Its colour is normally black.

Applications

Applications of polycarbonate include CDs (the discs), medical apparatus (sterilizable), kitchenware (microwaveable), light fittings, casings and housings, lenses, safety shields, and glazing.
