Methacrylamide (MAM) | Premium Specialty Monomer | CAS 79-39-0
Overview
Methacrylamide (MAM) is a white, highly pure crystalline powder. While it shares structural similarities with Acrylamide, the critical addition of a methyl group drastically alters its performance profile. This methyl group provides immense steric hindrance, rendering MAM-derived polymers exceptionally resistant to thermal degradation and hydrolytic breakdown. Furthermore, it boasts significantly lower toxicity compared to its acrylamide counterpart, making it the preferred monomer for high-end, human-contact applications.

At Shandong Yinglang Chemical Co., Ltd., established in 2011, we supply bulk volumes of Ultra-High Purity Methacrylamide (≥ 99.0%) to multinational specialty resin formulators, optical medical device manufacturers, and advanced textile chemical producers. Shipped safely as Non-Dangerous Goods, our MAM guarantees impeccable optical clarity, superior cross-linking capabilities, and long-lasting stability.
For optical-grade hydrogels and premium clear coatings, high purity and low color are mandatory. Typical specifications:
| Purity (Methacrylamide) | ≥ 99.0% |
|---|---|
| Moisture / Water | ≤ 0.5% |
| Methacrylic Acid | ≤ 0.1% |
| Color (APHA, 20% solution) | ≤ 20 |
| Melting Point | 108°C - 111°C |
- Optical Hydrogels: A critical monomer copolymerized to manufacture soft contact lenses and intraocular lenses, imparting hydrophilicity and dimensional stability without yellowing.
- Thermosetting Coatings: Provides reactive cross-linking sites in acrylic resins to create automotive clear coats with exceptional hardness and solvent resistance.
- Textile Finishes: Utilized to synthesize durable press (crease-resistant) finishes for premium fabrics.
- Specialty Adhesives: Formulated into adhesives demanding high heat resistance and strong bonding to glass/metals.
For manufacturers of optical polymers (like contact lenses) and premium automotive clear coats, yellowing or degradation under UV exposure and heat is a fatal flaw. By replacing standard acrylamides with Yinglang Chemical's High-Purity Methacrylamide, you introduce robust steric hindrance into your polymer chains. This uniquely protects the amide bonds from hydrolysis and oxidation, ensuring your final products remain crystal clear, structurally rigid, and chemically stable for years.
As a stable, crystalline solid, we offer cost-effective and secure bulk packaging for global ocean transit:
- 25 KG Multi-wall Kraft paper bags with heavy-duty PE inner liners.
- 25 KG Fiber Drums (Highly recommended for optical and medical clients).
- 500 KG Jumbo Bags (FIBC).

FAQ
Q1: What documents and certifications do you provide?
A Standard shipment includes COA (Certificate of Analysis) and MSDS (SDS). We also provide ISO 9001 certification and support third-party inspections like SGS or BV upon request.
Q2: Do you provide custom synthesis or formulation services?
A Yes. If you have specific purity requirements or a unique formulation, our R&D team can provide custom synthesis and adjust the stabilizers/inhibitors to meet your technical specifications.
Q3: What are your terms of payment?
A
For Orders ≤ $1,000: 100% in advance.
For Orders > $1,000: 30% T/T in advance, and the balance before shipment or against the copy of B/L. Irrevocable L/C at sight is also acceptable for bulk orders.
Q4: How long is your price valid?
A Chemical prices fluctuate due to the changes in raw material costs and exchange rates. Please contact our sales team for the latest real-time quotation.
Q5: What packaging and shipping ports are available?
A
We normally ship from Qingdao, Shanghai, or Ningbo.
Standard packaging includes 200kg Drums or 1000kg IBC Totes. We ensure strict safety compliance for both general and hazardous chemical cargoes.
Q6: It's my first time importing chemicals — can you help?
A Absolutely. Importing chemicals requires specific documentation. Our experienced logistics team will assist you with the entire process, including handling customs clearance documents and arranging the most suitable shipping method.
