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.
