Glycidyl Methacrylate (GMA)

High-purity bifunctional acrylic monomer with both polymerizable vinyl and reactive epoxy groups. Manufactured by Weicheng Advanced Materials with exclusive optimized process, purity reaches world-leading 99.9%. Main raw material for PGMA, widely used in coatings, biomedical media, environmental adsorbents and electronic functional materials.

1. Basic Information

• Full Name: Glycidyl Methacrylate

• Abbreviation: GMA

• CAS No.: 106-91-2

• Molecular Formula: C₇H₁₀O₃

• Appearance: Colorless transparent low-viscosity liquid

• Raw Material for: Poly(glycidyl methacrylate) (PGMA)

2. Chemical Structure & Core Properties

Each molecule contains one polymerizable methacrylate double bond and one strained epoxy oxirane ring, bringing dual reactivity:

1. C=C double bond: Undergoes free radical polymerization to synthesize PGMA homopolymer or copolymers with MMA, styrene etc.

2. Epoxy ring: Supports ring-opening modification with amines, carboxylic acids, thiols after polymerization.

Key Physical Index (Weicheng Industrial Grade):

• Purity: ≥99.85%, peak up to 99.9%

• Chroma (APHA): ≤10 (ultra-light color)

• Acid Value: ≤0.05 mgKOH/g

• Moisture: ≤0.03%

• Stabilizer: MEHQ (customizable dosage)

3. Weicheng Exclusive Manufacturing Advantage

Weicheng Advanced Materials (Shandong) Co., Ltd. optimizes the two-step epichlorohydrin synthesis route with proprietary digital control technology: full nitrogen sealed production, precise low-temperature cyclization, custom multi-stage high-vacuum rectification.Our GMA achieves ultra-high purity with minimal trace impurities, outperforming regular industrial standards worldwide. Low chroma ensures downstream PGMA powder maintains pale white color and stable epoxy functional content.

4. Main Applications

1. Monomer to synthesize PGMA reactive polymer powder

2. Crosslinkable functional monomer for industrial coatings, printing inks

3. Adhesion promoter additive for composite materials

4. Raw material for bioseparation microspheres, environmental heavy-metal adsorbents

5. Surface modifier for electronic optical films & circuit fillers

Manufacturing Process Introduction | Weicheng Advanced Materials (Shandong) Co., Ltd.

Weicheng Advanced Materials (Shandong) Co., Ltd. adopts the mature two-step epichlorohydrin synthesis route for glycidyl methacrylate (GMA) mass production, combined with our exclusive self-developed proprietary technology to optimize every production stage.

• Digital DCS temperature control system strictly restrains side reactions and monomer polymerization;

• Custom multi-stage high-vacuum precise rectification equipment achieves ultra-high impurity separation efficiency;

• Full nitrogen sealed production line avoids oxidation and moisture contamination.

With this optimized integrated process, our GMA monomer reaches a maximum purity of 99.9%, with bulk lot purity consistently above 99.85%, far exceeding the global general industrial standard of 98.5%. Ultra-low chroma, acid value and moisture content rank among the world’s highest levels of purity. High-quality GMA raw material guarantees light color, stable epoxy value and excellent modification performance of downstream PGMA polymer products.

Our factory owns a 6,000 tons annual capacity GMA production line with full digital monitoring. All products are EU REACH registered, widely exported to Europe, America, Japan, South Korea and other global markets for coatings, electronics, biomedical and environmental adsorption materials.
