摘要:
The present invention relates to polycarbonate-ABS moulding compositions provided with phosphonate amines, which moulding compositions exhibit excellent flame protection and very good processing properties, such as improved flow properties, improved modulus of elasticity and reduced formation of a coating on the tool, the graft polymer being prepared by means of mass, solution or mass-suspension polymerization processes.
摘要:
An oligophosphate of general formula is disclosed. The oligophosphate is suitable as a flame retardant for thermoplastic molding compositions that exhibit a good flame-retardant effect, improved dimensional stability under the effect of heat, a good level of toughness and excellent flowability.
摘要:
A thermoplastic molding composition comprising polycarbonate, an impact modifier, a phosphorus-containing flameproofing agent, and high purity talc is disclosed. The composition offers flame resistance for molded parts having small wall thickness, improved rigidity and resistance to stress cracking. The talc has MgO content of 30.5 to 32 wt. %, SiO2 content of 60 to 62.5 wt. % and Al2O3 content lower than 0.7 wt. % and d50 value less than or equal to 2.5 &mgr;m.
