Description

Poly(Vinylidene Chloride-Co-Methyl Acrylate) is a high-performance copolymer known for its exceptional barrier properties against gases and moisture. This material is critical for applications demanding long-term product protection and shelf-life extension. It is primarily sought by manufacturers in the packaging, coatings, and specialty film industries for creating impermeable layers.

Application

• Primary component in high-barrier food packaging films (e.g., for nuts, coffee, cheese, and meat).
• Gas barrier coating for pharmaceutical blister packs and medical device packaging.
• Manufacture of monofilaments and fibers for industrial and technical textiles.
• Base polymer for waterborne barrier coatings applied to paper, paperboard, and plastic substrates.
• Adhesive and sealant formulations requiring low permeability and chemical resistance.
• Component in specialty paints and coatings for corrosion protection.
