Description

Poly(Vinylidene Chloride-Co-Acrylonitrile) is a high-performance copolymer known for its excellent barrier properties against gases, moisture, and organic solvents. This material is critical for applications requiring superior chemical resistance and low permeability. It is primarily utilized by manufacturers in the packaging, fiber, and specialty coatings industries seeking to enhance product shelf life and durability.

Application

• Barrier Packaging Films: Used as a core layer in multi-layer films for food and pharmaceutical packaging to provide exceptional oxygen and moisture barrier.
• Synthetic Fibers: Employed in the production of flame-retardant and chemical-resistant fibers for industrial textiles and filtration media.
• Protective Coatings: Formulated into coatings for wires, cables, and metal surfaces to provide corrosion and chemical resistance.
• Adhesive Components: Serves as a key resin in solvent-based adhesives requiring strong bonding and resistance to oils and fuels.
• Membranes: Utilized in the manufacture of specialty separation membranes for chemical processing due to its solvent stability.
• Automotive Components: Incorporated into under-the-hood parts and fuel system components where chemical resistance is paramount.
