2.10. Scraping force
Scraping force is the force required to scrape the tablet off the punch face. The force is measured by using the shear stress of the scrapper. Scrapping force is related to the sticking tendency during the tableting process.
The final blends were compressed to flat-faced tablets with a diameter of 8 mm and a mass of 200 mg on an eccentric press (Korsch EK0, Korsch) at 5 kN. The scrapping force of this evaluation was defined as the shear stress after producing 30 tablets.
