    As an accredited Methyltetrahydrophthalic Anhydride factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.

    Packing & Storage
    Packing Methyltetrahydrophthalic Anhydride is packaged in a 25 kg net weight steel drum, sealed, labeled with hazard symbols and handling instructions.
    Shipping Methyltetrahydrophthalic Anhydride should be shipped in tightly sealed, corrosion-resistant containers, protected from moisture, and clearly labeled according to hazardous material regulations. Transport in a cool, well-ventilated area, away from incompatible substances such as water and strong bases. Follow all local, national, and international guidelines for hazardous chemicals during transit.
    Storage Methyltetrahydrophthalic Anhydride (MTHPA) should be stored in a cool, dry, well-ventilated area, away from moisture, heat sources, and incompatible materials such as strong bases and amines. Keep containers tightly closed and protected from physical damage. Use corrosion-resistant containers, and ensure proper labeling. Minimize exposure to air, as MTHPA is sensitive to moisture and may hydrolyze.
