Talc as Reinforcing Filler in Polypropylene Compounds: Effect on Morphology and Mechanical Properties

Ammar O, Bouaziz Y, Haddar N and Mnif N

Talc represents one of the most useful mineral fillers which are compatible with the polypropylene (PP). It is characterized with its lamellar structure. The introduction of 30% by weight of talc, three types differing with the particle size d50 and the composition, has not only a positive influence on stiffness and crystallinity but also it decreases the impact strength and tenacity. The abrasive wear behavior depends mainly on the particle size of talc. Microscopic observations revealed that the talc layers are aligned along the injection flow direction, and uniformly dispersed in the PP matrix.
