come from kaolin and talc, while Mg signals are from talc only. Al signals are concentrated in alumina. According to the color matching rules, the cyan area distribution is talc; the yellow area distribution is kaolin; the red area distribution is alumina. It can be seen that talc and kaolin are uniformly mixed together with alumina particles.
Composites Based on Polypropylene and Talc: Processing
iPP/Talc composites were produced, with different methods of filler addition in iPP matrix. Two different grades of Talc were used for comparison. The tensile tests results showed that talc particles promoted an improvement in composite rigidity, indicating the reinforcing effect of the talc particles in the iPP matrix. However, PP/talc-based composites that …

Crystallization improvement of PLA by the talc with
As an inorganic filler, the fine particle talcum powder exhibits the poor compatibility when blended with polymers. By the "grafting from" method, a modified talcum powder (Talc-g-pla) was synthesized by the ring-opening polymerization (ROP) of lactide in bulk. The polymer chains grew in situ and chemically grafted on the talc surface, which …

The size of the talc particles influences the burning behaviour of the composites. The addition of talc delayed the combustion process and decreased the combustion temperature by more than 10%. The biggest difference in relation to the polymer matrix was obtained for the composites with particles of ≤250 µm in size.
