Description

Methyl Methacrylate CAS NO 80-62-6 is a key monomer in the acrylic polymer family, characterized by its clear, colorless liquid form and distinctive, sharp odor. This compound is essential for producing high-performance polymers with exceptional clarity, weather resistance, and durability. It is a critical raw material for manufacturers in the plastics, coatings, adhesives, and construction industries seeking to create premium, long-lasting products.

Application

• Acrylic Sheet (PMMA) Production: The primary use for manufacturing cast, extruded, and molded sheets for signage, skylights, sanitaryware, and automotive glazing.
• Surface Coatings & Paints: Serves as a vital component in water-based and solvent-based acrylic resins for automotive, industrial, and architectural paints, providing excellent gloss and UV stability.
• Adhesives & Sealants: Used in the formulation of high-strength acrylic adhesives, caulks, and construction sealants.
• Emulsion Polymers: A key monomer for producing acrylic emulsions used in textile finishes, leather coatings, and paper treatment.
• Dental & Medical Applications: Employed in the manufacture of dental prosthetics, bone cements, and other medical devices requiring biocompatibility and strength.
• Impact Modifiers: Used as a comonomer to improve the impact resistance and processability of other polymers like PVC.

Quality Control

Our Methyl Methacrylate is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) for every shipment, detailing key parameters such as assay, inhibitor content, and impurity profiles. Our quality commitment aligns with global standards for industrial and specialty chemical manufacturing.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and ignition points. Due to its highly volatile and light-sensitive nature, containers should be kept tightly sealed and under an inert atmosphere (e.g., nitrogen) to prevent premature polymerization. Recommended storage temperature is 15-25°C.
