Methyl methacrylate (MMA) is an important organic chemical monomer, mainly used in the synthesis of polymers. It is a colorless, transparent liquid at room temperature, highly volatile, and has a pungent odor.
It is primarily used in the synthesis of homopolymers or copolymers. Its main applications cover the synthesis of high-performance plastics, coatings, adhesives, textile printing and dyeing auxiliaries, optical materials, and electronic information devices, among other industrial fields.

Q1: What is Methyl Methacrylate (CAS 80-62-6) and what is its main industrial use?
A: MMA, this high-activity specialty ester is an essential reactive acrylic monomer. Its primary B2B industrial use is serving as the fundamental building block to synthesize Polymethyl Methacrylate (PMMA) acrylic plastics, optical sheets, automotive paints, synthetic solid surfaces (artificial marble), and high-strength structural adhesives.
Q2: Why is the choice of polymerization inhibitor (MEHQ) so critical when importing bulk MMA?
A: Because MMA is highly reactive, it can undergo spontaneous and dangerous self-polymerization under heat or light, potentially ruining entire liquid container shipments. To prevent this, we add a specific ratio of MEHQ . The inhibitor blocks active free-radical chain reactions. For customers planning long-distance tropical ocean transit, we can tailor higher inhibitor concentrations to guarantee total cargo stability and safety.
Q3: Can your MMA monomer be used directly for optical-grade PMMA sheet casting?
A: Yes. For optical-grade applications, color and purity are paramount. Our Methyl Methacrylate monomer maintains an exceptionally high purity assay of ≥99.9% with an ultra-low APHA color index of ≤5. This eliminates unwanted yellowing, haziness, and micro-impurities, allowing acrylic manufacturers to cast highly transparent sheets with light transmission rates exceeding 92%.
Q4: Where can I buy bulk, high-purity MMA monomer at direct petrochemical wholesale prices?
A: You can choose us. We guarantee a minimum purity assay of ≥99.9% in standard 190kg steel drums, 950kg IBCs, or bulk ISO tanks. Contact our global chemical export desk today to get an instant wholesale spot price quote or to request a 500ml laboratory evaluation sample!
