摘要:
The present invention relates to a polycarbonate composition comprising polyalkyl(alkyl)acrylate having a specific molecular weight and an impact modifier, as well as to moulded bodies obtainable from these compositions. Compositions according to the present invention exhibit superior properties, in particular with respect of low-temperature strength and melt flowability.
摘要:
The present disclosure relates to impact-modified polycarbonate compositions which comprise a graft polymer containing silicone/acrylate composite rubber as the graft base, wherein the content of silicone rubber is 65-95 wt. % (based on the graft base), talc having a d98 value (also called “top cut”) of less than 20 μm and phosphorus-containing flame retardant, the use of the polycarbonate compositions for the production of shaped articles and the shaped articles themselves. The compositions and moulding compositions according to the disclosure have an optimum combination of good flameproofing, good resistance to chemicals and hydrolysis and good mechanical properties (i.e. in particular a high E modulus and high notched impact strength aK).
摘要:
