Description

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

Application

• Barrier Coatings for Food Packaging: Used as a thin coating on films and papers to provide an excellent oxygen and moisture barrier, extending the shelf life of snacks, meats, and dairy products.
• Multilayer Film Structures: A key component in co-extruded films for medical device packaging and high-value industrial product wraps where a high barrier is essential.
• Pharmaceutical Packaging: Employed in blister packs and bottle liners to protect sensitive drugs from moisture and atmospheric gases.
• Adhesive and Sealant Formulations: Imparts chemical resistance and low permeability in specialty adhesives and sealants for construction and automotive applications.
• Wire and Cable Insulation: Used in specific grades to provide flame-retardant and chemical-resistant insulation layers.
• Industrial Protective Coatings: Applied as a corrosion-resistant coating for metal and concrete surfaces in aggressive environments.
