Polyvinylidine chloride (Saran) is a tough plastic which is extensively used in laboratory drainpipes. This form of the plastic is rigid, but flexible transparent films are used widely in food packaging. Polyvinylidine chloride becomes brittle at 10°C and loses most of its strength at 77°C. It has unusually low permeability...

Plastic latices are useful in making articles that do not have to be resilient, but in which tough, somewhat hard deposits are desired. They are particularly suitable for paper and fabric coating. Typical plastic latices are modified polyvinyl chloride and polyvinylidine chloride. 

Acrylic ester polymers and their copolymers with styrene or methyl methacrylate can be readily prepared with a wide range of Tg s, but vinylidine chloride presents problems. Its Tg is normally given as 255°K, which is the glass transition temperature of the amorphous polymer. Polyvinylidine chloride behaves as a crystalline polymer for which the glass transition occurs at about 370 - 410°K and calculations of glass transition temperatures are pointless for this monomer. 

The materials used in nonwoven fabrics include a single polyolefin, or a combination of polyolefins, such as polyethylene (PE), polypropylene (PP), polyamide (PA), poly(tetrafluoroethylene) (PTFE), polyvinylidine fluoride (PVdF), and poly(vinyl chloride) (PVC). Nonwoven fabrics have not, however, been able to compete with microporous films in lithium-ion cells. This is most probably because of the inadequate pore structure and difficulty in making thin (<25 /rm) nonwoven fabrics with acceptable physical properties.
