【Chemical Name】N,N'-Methylenebisacrylamide (MBA)
【Other Name】N,N'-Methylenebis(acrylamide); BIS; MBA; Bis-acrylamide; N,N'-Methylenediacrylamide; N,N'-Methylenebis(2-propenamide)
【CAS No.】110-26-9
【Molecular Formula】C₇H₁₀N₂O₂
【Molecular Weight】154.17 g/mol
【Product properties】
N,N'-Methylenebisacrylamide is a white to off-white crystalline powder, odorless, with minimal hygroscopicity. It is sensitive to light and air; exposure to high temperature or strong light may induce self-crosslinking. Slightly soluble in cold water, soluble in ethanol, acetone, and methanol, insoluble in petroleum ether and benzene.
Solubility in water: approx. 3 g/L at 25°C. Melting point: >300°C (lit.) / 184-185°C (decomposition). Density: 1.235 g/cm³ / 1.352 (30°C). Vapor density: 5.31-5.32 (vs air). pH: ≥5.0 (25 g/L H₂O, 20°C). Purity: ≥99.0%.
【Storage】
Store in a cool, dry, well-ventilated area. Keep containers tightly sealed, protected from light, moisture, heat, and direct sunlight. Recommended storage temperature: 2-8°C. Avoid storage with oxidizing agents and strong acids/alkalis. Shelf life: up to 60 months under proper conditions.
【Packing】
Available in various packaging options to meet customer requirements: 100g, 500g, 1kg, 5kg, 25kg/bag, 25kg/fiber drum, or customized upon request.
【Application】
N,N'-Methylenebisacrylamide is a highly efficient cross-linking agent widely used across multiple industries:
- Electrophoresis & Molecular Biology: Used as a cross-linker in the preparation of polyacrylamide gels (PAGE) for the separation of proteins and nucleic acids. The concentration of MBA determines the pore size of the gel.
- Polymer Synthesis: Cross-linking agent for polyacrylamides, hydrogels, superabsorbent resins, and epoxy resin adhesives.
- Water Treatment: Used as an auxiliary cross-linking agent for flocculants, improving sludge dewatering efficiency and flocculation performance.
- Coatings & Adhesives: Enhances adhesion, water resistance, and mechanical strength of waterborne coatings and pressure-sensitive adhesives.
- Oilfield & Construction: Used as a water-plugging agent in drilling operations, chemical grouting, and reservoir permeability control.
- Paper Industry: Serves as a paper strengthening agent, improving dry/wet tensile strength and sizing effect.
- Medical & Cosmetic Fields: Used in the preparation of biological gels, tissue engineering scaffolds, and as a thickener/emulsifier in cosmetics.
- Photosensitive Resins & Printing: Raw material for photosensitive nylon/photosensitive plastics, also used in photography, printing, and plate-making.
