Introduction
Polyvinylidene chloride (PVDC) liquid is a widely used material known for its excellent barrier properties, particularly in the packaging and pharmaceutical industries.
PVDC Liquid Overview
Chemical Composition
PVDC is produced by the polymerization of vinylidene chloride monomers with other monomers such as acrylic esters or acrylonitrile to enhance its processing and application flexibility.
Physical Properties
PVDC liquid exhibits high barrier resistance to gases and vapors, with an oxygen transmission rate (OTR) as low as 5 cm³/m²/day. Its water vapor transmission rate (WVTR) can be as low as 0.5 g/m²/day, making it ideal for applications that require high moisture and air barrier properties.
Applications of PVDC Liquid
Packaging Industry
In the packaging sector, PVDC liquid is primarily used in the food industry to extend shelf life due to its ability to form a film that acts as a barrier to oxygen, moisture, and other gases.
Pharmaceutical Industry
PVDC's barrier properties make it suitable for pharmaceutical blister packaging, where it helps in protecting sensitive products from oxygen and moisture contamination.
