Description

DF-1 is a high molecular plant fiber shattered into different sizes, then it is organically modified together with a certain amount of regulator. It has the characteristics of small routine dosage, good anti-caving and plugging effect as well as excellent filtration loss-reducing effect, so it is a highly efficient mud treating agent.
