Microspheres for Well cement - Yanheal 380

The core advantage of closed-cell perlite as a cement weight-reducing agent lies in its ability to lower cement paste density and improve its rheological properties. The spherical closed-cell structure significantly reduces cement paste density, preventing formation fracturing or paste loss due to excessive density, thus ensuring the paste fills to the predetermined height. Simultaneously, it enhances paste stability, forming a uniform spatial network structure and reducing stratification.
