LCPs are polymers whose chains form so-called liquid crystalline phases in the melt. In crystals there is generally a fixed order, whereas in liquids/melts the distribution of molecules or atoms is usually largely random. LCPs are resistant to hydrolysis, weak acids and bases, alcohols, aromatics, chlorinated hydrocarbons, esters, ketones and all chemicals that would otherwise cause stress cracking, with the exception of strongly oxidising acids and strong alkalis, over a wide temperature range. The weathering stability and resistance to gamma rays and short waves are good. They are inherently flame-retardant (V0 according to UL 94) and have very good electrical properties – with the exception of low tracking resistance.
