Polikarbonat (PC) Cas št.: 25037-45-0 Hot Selling

Polikarbonat je poliester, v katerem so dihidrični (ali polihidrični) fenoli povezani preko karbonatnih vezi. Polikarbonati so najtrši med vsemi termoplasti. So prozorni kot okno, neverjetno močni in togi, jih je mogoče avtoklavirati in niso strupeni. Imajo temperaturo krhkosti 135 stopinj.

Polycarbonates are plastics widely used in modern industry having good temperature and impact resistance. This plastic is particularly good to work with more conventional definition techniques (injection molding, extrusion into tubes or cylinders and thermoforming). It is also used when optical transparency is needed, having more than 80% transmission up to the 1560-nm range (short wave infrared range). It has moderated chemical resistance properties, being chemically resistant to diluted acids and alcohols. It is poorly resistant against ketones, halogens, and concentrated acids. The major disadvantage associated with polycarbonates is the low glass transition temperature (Tg>40 stopinj), vendar se še vedno v veliki meri uporablja kot poceni material v mikrofluidnih sistemih in tudi kot žrtvena plast.
