Product Overview

Methyl Acrylate (MA) is a versatile monofunctional acrylate monomer, synthesized through the esterification of acrylic acid with methanol. It is widely utilized in the production of polymers and copolymers, offering enhanced hardness, strength, and adhesion properties. MA’s high reactivity and low glass transition temperature make it suitable for various applications across multiple industries.

Key Applications

1. Polymer and Resin Production

  • Acrylic Fibers: MA is copolymerized with acrylonitrile to produce acrylic fibers, which are used in textiles, carpets, and upholstery.

  • Coatings: Incorporated into coatings to provide enhanced durability, UV resistance, and adhesion to various substrates.

  • Elastomers: Used in the synthesis of elastomers that require flexibility and resilience.

  • Molding Resins: MA-based resins are employed in molding applications requiring precise detail and strength.

2. Adhesives and Sealants

  • Pressure-Sensitive Adhesives: MA is a key component in the formulation of adhesives that bond to surfaces without the need for heat or solvent activation.

  • Sealants: Provides flexibility and adhesion in sealants used in construction and automotive industries.

3. Textiles and Fibers

  • Fiber Processing Agents: MA is used in the treatment of fibers to enhance properties such as strength, water resistance, and dye uptake.

  • Textile Backcoatings: Applied as a backcoating to textiles to improve durability and resistance to wear.

4. Packaging Materials

  • Barrier Films: MA-based polymers are used in the production of films that provide barriers to gases and moisture, extending the shelf life of packaged goods.

  • Flexible Packaging: Contributes to the flexibility and strength of packaging materials.
