摘要:
The invention relates to flameproof compositions consisting of polycarbonate or polyester carbonate and certain salts as well as polytetrafluorethylene (PTFE) blends.
摘要:
The invention relates to the use of impact-resistant modified polycarbonates with especially good low-temperature properties and an especially good ESC behaviour, for using in fields in which especially good low-temperature properties and an especially good ESC behaviour are required, e.g. in the automobile industry or for outdoor use. The invention also relates to said novel modified polycarbonate compositions and to moulded bodies and extrudates consisting of the same.
摘要:
A thermoplastic molding composition that features improved low-temperature properties and is thus suitable for application in exterior automotive parts is disclosed. The composition contains (A) 80 to 60 percent of a copolycarbonate wherein 65 to 75 mole percent of its structural units are derived from compounds of formula (I) wherein R1, R2, R3 and R4 independently of one another represents H, C1-C4-alkyl, phenyl, substituted phenyl or halogen, and wherein 25 to 35 mole percent of its structural units are derived from compounds of formula (II) where R5, R6, R7, and R8 independently one of the others denote H, CH3, Cl or Br and X is C1-C5-alkylene, C2-C5-alkylidene, C5-C6-cycloalkylene, C5-C10-cycloalkylidene and (B) 20 to 40 percent of a homopolycarbonate of bisphenol A having a melt flow rate, determined in accordance with ASTM D-1238 under 1.2 kg loading at 300 °C of 3 to 12 gm/10 minutes.

摘要:
The invention relates to a continuous method for producing, by using microparticles, thermoplastics provided with reinforcement fibres. The production methods relate to such composite materials, which contain the reinforcement fibres in a parallel (or predominantly parallel) arrangement in the thermoplastic matrix.
摘要:
The present invention relates to polycarbonate compositions for producing halogen-free moulded parts for use in public facilities which meet the corresponding fire protection regulations and standards. The present invention also relates to the use of halogen-free polycarbonate compositions for producing moulded parts, particularly seating and/or parts of seating, e.g. seat shells, which are flame-retardant and meet the standards for use in public buildings, as well as the moulded parts themselves.
