Buyer-facing sourcing candidate for an oilfield coiled tubing drag reducing agent supplied as a yellow liquid, model MDR-50. The listing indicates use in oilfield production and drilling additive applications, with specific gravity 0.9–1.1 and solubility in water or acid. Overseas buyers should verify the exact chemical identity or mixture composition, CAS coverage if applicable, active concentration, temperature and acid compatibility range, impurity limits, COA/MSDS/TDS availability, DG classification, and export documentation before RFQ or sample approval.
