Bridge-Fill-Seal (B.F.S.) was developed by Turbo-Chem’s R&D laboratory in line with the Ideal Packing Theory. The coarse particles in B.F.S. will cause a bridge while smaller particles fill the gaps in between and the finest particles will complete the seal inside the fracture. B.F.S. will not “grind” down like brittle generic LCM, which leads to constant treatment, an increase in ECD and formation damage.
