PGA fully degradable frac ball is a series of frac plug 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.
