Mica was incorporated in ABS/PC:65/35 blends prepared on a Haake Torque Rheometer System 9000 with Rheomix 600 mixer. To improve the polymer/filler interaction, a treatment using silane on mica surface was performed. Studies were conducted concerning mechanical properties (flexural and impact strength), thermal properties (DSC and Vicat softening temperature), rheology, and flame retardancy. The composition with 30 phr of mica gives the best properties and efficiency in reducing the rate of burning, then becoming an alternative material to be explored and possibly meet the new requirements sought by these market blends. © 1999 John Wiley & Sons, Inc.
