Methyl Methacrylate (MMA)

METHYL METHACRYLATE (MMA) 190KG – KEY ACRYLIC MONOMER FOR PMMA AND SYNTHETIC RESINS

Methyl Methacrylate (MMA) is a key acrylic monomer, a colourless liquid that polymerises readily. It is the main raw material for PMMA (acrylic glass), acrylic resins, paints, adhesives and many polymer products.

PRODUCT INFORMATION / Introduced packaging: 190 kg/drum. The product is a flammable monomer liquid with a polymerisation inhibitor. Acceptance criteria must be based on the COA of the actual batch delivered.

1. What Is METHYL METHACRYLATE (MMA) 190KG?

Methyl Methacrylate (MMA) is an organic compound with the formula C5H8O2, a colourless liquid with a characteristic odour. Thanks to its reactive vinyl group, MMA readily polymerises into polymethyl methacrylate (PMMA) and copolymerises with many other monomers. It is an important raw material for acrylic resins, paints, adhesives, films and many polymer products.

5. Instructions for Use

• Use according to the technical guidance and recommended parameters of the manufacturer.
• Blend only with materials whose compatibility has been assessed.
• Perform compatibility and small-scale tests before full-scale production.
• Check shelf life, container condition and labels before use.
• Do not mix with incompatible chemicals without a technical assessment.

6. Safety, Storage and Transportation

• Wear safety goggles, gloves, organic-vapour respirator and protective clothing when handling Methyl Methacrylate.
• Work in a well-ventilated area; vapours are heavier than air and may accumulate in low-lying areas.
• Store in a dry, cool warehouse away from heat sources; keep drums on pallets.
• Keep containers closed when not in use; keep away from open flame, sparks, static electricity and heat sources.
• Separate from strong oxidisers and incompatible chemicals.
• Do not discharge large quantities into drains, surface water or groundwater.
• Protect cargo from rain, secure the load and keep labels intact.
• If large amounts of vapour are inhaled, move the person to fresh air and seek medical attention. In case of eye contact, rinse with clean water for at least 15 minutes.

7. Selection and Acceptance Criteria

• Verify the COA of the actual delivered batch against the technical requirements.
• Check appearance, colour, clarity and visible impurities.
• Check container condition, seals, labels and traceability information.
• Review the SDS for storage and emergency handling.
• Check homogeneity, water-insoluble matter and batch-specific parameters.
