PGA Frac Ball https://www.eastnewmaterial.com/PGA-Frac-Ball.html ​PGA fully degradable frac plug ball is a series of frac plug balls developed based on PGA degradable materials to meet the needs of oil fields under various temperatures and working conditions.It has the following characteristics: High pressure-bearing strength: the material itself has high strength, ≥50 MPa Good degradability: completely degraded, no viscosity after degradation; Time controllable: The blocking time can be adjusted by adjusting the material formula; Safe and environmentally friendly: After degradation, water and carbon dioxide are eventually generated, which is pollution-free; Easy to operate: it can be added directly to the sand mixing truck and is easy to use.
