Talc Surface Treatment Process

Talc mediates angiostasis in malignant pleural effusions

Talc remains the most effective sclerosing agent for pleurodesis. However, its mechanism of action in resolving pleural malignant disease remains unclear. The present study evaluated the angiogenic balance in the pleural space in patients with malignant pleural effusions (MPE) following talc insufflation. Patient pleural fluid samples were collected both before and after talc insufflation.

This is probably because the orientation of talc in longitudinal direction during the molding process led to large improvement in the bending strength. Besides, as the accelerated weathering proceeded to 1,000 h, flexural strength of pure PP significantly decreased, but there were relatively small differences in the flexural strength of the
