Enteric polymer with pH-dependent solubility—insoluble below pH 5.0 and soluble above pH 5.5.
High purity grade formulated without residual solvents or plasticizers, meeting stringent pharmaceutical excipient requirements.
Excellent film-forming capability for robust, pinhole-free coatings on tablets and pellets.
Consistent batch-to-batch performance validated through rigorous quality control and USP/NF compliance testing.
Thermally stable with low moisture uptake, supporting long-term storage stability of coated dosage forms.
Gastro-resistant tablet coatings to prevent drug release in the stomach and enable targeted intestinal delivery.
Enteric protection for acid-labile active pharmaceutical ingredients (APIs) such as proton pump inhibitors and antibiotics.
Functional film coating for modified-release multiparticulate systems including beads and granules.
Excipient in oral solid dosage forms compliant with USP <85>, EP 2.6.13, and JP standards.
Base polymer for hot-melt extrusion formulations requiring pH-responsive dissolution behavior.
