CPL is a powder polymer, mainly used to reduce filtration of drilling fluid. CPL is uniquely stable, easily handled and useful in fluids based on fresh water and saline water environments.

Advantage:
-Strong cutting encapsulation for non-relative solids
– High lubricity reduces torque
– Eliminate swelling bit bailing and sticking
-Easily disperse in freshwater
-Work well with CX-DET
