Polyvinylidene chloride, commonly known as PVDC, is a versatile polymer that is widely used in various industries for its excellent barrier properties. This polymer is a type of vinyl polymer, derived from vinyl chloride, which is a colorless gas with a sweet odor.
Properties of Polyvinylidene Chloride
PVDC is known for its high barrier properties against gases, water vapor, and odors, making it ideal for packaging applications. It is a thermoplastic polymer, meaning it can be easily molded and reshaped when heated. Additionally, PVDC is highly resistant to oils, greases, and chemicals, adding to its durability.
Applications of PVDC
One of the most common uses of PVDC is in food packaging, where its barrier properties help in extending the shelf life of perishable goods. It is often used as a coating on films or as a component in multi-layer structures to provide protection against moisture and oxygen. PVDC is also utilized in the production of medical packaging, where sterility and hygiene are crucial.
Environmental Impact
While PVDC offers excellent barrier properties, its environmental impact has raised concerns. The polymer is not easily recyclable and can release harmful substances if incinerated. Efforts are being made to develop more sustainable alternatives to PVDC in packaging applications to reduce its environmental footprint.
In conclusion, polyvinylidene chloride is a valuable polymer in various industries due to its exceptional barrier properties and chemical resistance. However, its environmental impact highlights the need for sustainable alternatives to ensure a greener future.
