Saltemp-polymer Filtration Reducer

FC-FR200S polymer filtration reducer is a high temperature & salt resistant fluid loss additive, equivalent to DRISTEMP for water-based drilling mud.

It is copolymerized with AMPS/NN and other anti-salt monomers, with hydrolysis-resistant molecular structures added to boost thermal stability up to 230°C. Rich adsorption groups (-CONH2, -SO3H, -COOH) on its molecular chain bind free water tightly and build tight filter cakes to cut fluid loss drastically.

Practical Product Strengths

01/

Broad compatibility with all common water-based mud additives, no negative impact on mud rheology

02/

Steady fluid loss control across fresh water, calcium salt and high-salinity brine drilling systems

03/

Maintains reliable performance under long-term high temperature aging, upper limit reaches 230°C

04/

Improves solid suspension property of mud at elevated downhole temperatures
