What is the difference between polytrol fl 32 & fl 34?

Polytrol® FL 32 is a dispersing fluid loss additive Polytrol® FL 34 is a high-performance, non-retarding fluid loss additive Polytrol® FL 45 is a high-performance fluid loss additive Polytrol® FL 56 is a high-performance dispersing fluid loss additive

What is polytrol fl 29?

The Polytrol® FL line of products are effective fluid loss control chemicals for use in differing conditions and requirements, such as high temperatures and high salt concentrations. Polytrol® FL 29 is a dispersing fluid loss additive It’s dispersing effect permits the design of low viscosity slurries. A separate dispersant may not be needed

What is a high performance fluid loss additive?

It helps to handle slurries with reduced water/cement ration at temperatures up to 250 °F (121 °C). BASF’s portfolio of high performance fluid loss additives comprises three product which have gained industry wide acceptance and are known to work in a wide variety of well conditions (up to at least 400 °F) and slurry compositions.

What is hydrolyzed polyacrylamide (HPAM)?

Hydrolyzed polyacrylamide (HPAM), a derivative resulting from the hydrolysis of PAM, demonstrates significant thickening capabilities in freshwater and at relatively lower temperatures (<75 °C) due to strong intra- and inter-chain electrostatic repulsion of carboxylate groups 14.

What is partially hydrolyzed polyacrylamide (PHPA)?

Partially hydrolyzed polyacrylamide (PHPA), consisting of neutral acrylamide and anionic acrylate groups, is suitable for use in water with <25,000 mg/L TDS 12, 15.
