What is Methylenebisacrylamide?
Methylenebisacrylamide (CAS 110-26-9), commonly abbreviated as MBA, is a bifunctional crosslinking monomer used to build three-dimensional polymer networks.
Where is Methylenebisacrylamide used?
- Polyacrylamide gel production: determines crosslink density for electrophoresis gels used in laboratory and diagnostic manufacturing
- Personal care: incorporated into superabsorbent hydrogel systems and crosslinked thickeners for controlled water retention
- Polymer manufacturing: produces ion-exchange resins and water treatment gels, where network tightness affects ion selectivity and capacity for industrial filtration systems
- It also functions as a crosslinker in contact lens materials and drug delivery matrices.
Good to know: Precise swelling ratios are a specification requirement for high-performance medical and pharmaceutical applications.
Commercial specifications
- Purity levels typically at 99% or above for demanding polymerization
- Technical and high-purity laboratory grades
- Packaging ranges from small quantities for laboratory and specialty formulators to bulk bags for industrial polymer producers
