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:
A flame resistant thermoplastic molding composition having improved mechanical properties is disclosed. The composition contains polycarbonate, a graft polymer and a phosphorus compounds of formula (I): and a mixture of fluorinated polyolefins with polyalkyl (meth)acrylates.
摘要:
A thermoplastic molding composition containing talc is disclosed. The composition wherein talc has a median particle size of less than 1000 nm further contains a polycarbonate and/or polyester-carbonate, and a graft polymer having as graft base a rubber having a glass transition temperature of below about 10° C. is suitable for preparing molded articles having improved mechanical properties, such as weld line strength, elongation at break and toughness at low temperatures.
摘要:
A thermoplastic molding composition comprising polycarbonate resin, at least one impact modifier and highly pure talc is disclosed. The talc is characterized in that it contains Al2O3 in an amount of less than 1% relative to the weight of said talc. The composition that features high toughness, good processability and low coefficient of thermal expansion is suitable for the manufacture of exterior parts of vehicles.
