Abstract
The present invention concerns polycarbonate compositions filled with special talc, which are characterised by high toughness, rubber-glass transitions at low temperatures and good processability at low coefficient of thermal expansion.
Claims18
Compositions containing polycarbonate, at least one impact modifier and a highly pure talc, characterised by an Al2O3 content <1 wt. % relative to the talc.
Polycarbonate compositions according to claim 1 containing 50 to 90 wt. % of at least one aromatic polycarbonate, 1.5 to 25 wt. % of at least one graft polymer according to claim 9, 0 to 20 wt. % of a vinyl (co)polymer, and 1 to 20 wt. % of a talc according to the definition in claim 4, whereby the sum of the components is 100.
Use of the polycarbonate compositions according to one or more of the previous claims for the manufacture of mouldings or moulded parts of any type.
Mouldings or moulded parts obtainable from the polycarbonate compositions according to one or more of the previous claims.
