JOF TEMP is  a poly dispersant of sodium salts of sulphonated low molecular weight co-polymer of  Styrene & Malleic anhydride. It is a low viscosity, totally synthetic polymeric fluid loss control dispersant and shale stabilizing additive for water based drilling fluid. 
JOF TEMP is non biodegradable; thermally stable in excess of 450 - 500 oF  as well as at pressures in excess of 1,000 psi.  It provide excellent tolerance to pH extremes and is not adversely affected by CO2 contamination. JOF TEMP also performs well in the presence of strong poly valent cations, such as those found in oil field brines.
