Talc as Reinforcing Filler in Polypropylene Compounds:
The compound PP/Talc2 behaves like the unfilled PP, this result is due to a combined effect of purity and the average particle size. Talc1 and talc2 improve the abrasion’s resistance of compounds thanks to their behavior as a solid lubricant; talc’s platelets facilitate the slip on the interface specimen-abrasive disc.

What is Talc Pleurodesis: Complications, Side Effects, and
2024年6月25日 Talc pleurodesis installs talc in the pleural space to intentionally cause inflammation and fibrosis, which closes up the space between the lungs and the chest wall. During this procedure, a surgeon will typically spray a mixture of talc and saline through a tube into the chest area that surrounds the lungs. It may also be applied in powder form.
