Difference Between PVC and PVDC

The term PVC stands for polyvinyl chloride while the term PVDC stands for polyvinylidene chloride. The key difference between PVC and PVDC is that the PVC material is made of chloroethene monomers, whereas PVDC material is made of vinylidene chloride.

What is PVDC coating?

Poly-Vinylidene Chloride (PVDC) is a water-based coating often used to improve barriers and reduce permeability. It keeps food fresh, improves shelf life, and gives packaging an attractive high-gloss finish; all qualities that are behind the packaging industry's preference for plastic.

Is PVDC a plastic?

Properties. Polyvinylidene chloride or PVDC is a clear and flexible synthetic thermoplastic produced by the polymerization of vinylindene chloride. It is optically clear with a high degree of gloss and has outstanding oxygen and moisture barrier properties comparable to metallized films.

What does PVDC stand for?

Polyvinylidene chloride or Polyvinylidene dichloride (PVDC) is a homopolymer of vinylidene chloride.

What is difference between strip and blister packaging?

The difference between a strip pack and blister pack is that a strip pack does not have thermo-formed or cold formed cavities; the strip pack is formed around the tablet at a time when it is dropped to the sealing area between sealing moulds.

Is PVC a polymer?

What is PVC (PolyVinyl Chloride)? Polyvinyl Chloride (PVC or Vinyl) is an economical and versatile thermoplastic polymer widely used in building and construction industry to produce door and window profiles, pipes (drinking and wastewater), wire and cable insulation, medical devices, etc.

Is PVDC toxic?

Currently the only after-use options for PVDC are either landfill or incineration. Neither of these after-use pathways is considered environmentally friendly due to the release of toxic chemicals. When incinerated, PVDC generates considerable quantity of dioxins – a well-known potent human carcinogen.

How is PVDC made?

PVDC is made by the addition polymerisation of 1,1-dichloroethene (vinylidene chloride). The homopolymer is very difficult to process as it decomposes below its melting temperature.

How is PVC made?

PVC is produced by polymerization of vinyl chloride monomer (VCM). The main polymerization methods include suspension, emulsion, and bulk (mass) methods. About 80% of production involves suspension polymerization. ... The PVC is separated off and dried to form a white powder also known as PVC resin (see flow diagram).

What is polyvinylidene chloride used for?

Polyvinylidene chloride (PVDC), a synthetic resin produced by the polymerization of vinylidene chloride. It is used principally in clear, flexible, and impermeable plastic food wrap.

What is PVC foil?

PVC foil is an affordable material used today for decoration and aesthetic image. It is easy to cover your furniture with PVC foil. The most important point is that PVC foils are produced from substances which are harmless to health.
