Polyvinyl chloride (PVC) is a thermoplastic polymer of vinyl chloride. PVC is a strong material with high dielectric properties, has chemical resistance to alkalis, solvents, many acids and mineral oils. It does not burn in the air and has a low resistance to frost. Properties of PVC depend on the method of its production, which are divided into three types: suspension, emulsion and the method of polymerization in mass.
Polyvinylchloride suspension (PVC-S) – is produced by suspension polymerization. It is often also referred to as suspension polyvinyl chloride resin. PVC-S has relatively narrow molecular weight distribution, high purity, low water absorption, good dielectric properties, good heat and light resistance.
It is used in manufacturing of profiles, siding, cable compounds, sheets, pipes, various types of films including films for suspended ceilings, artificial leather, polyvinyl chloride fiber, foam polyurethane, footwear PVC compounds, furniture edges.
Polyvinyl chloride emulsion (PVC-E) is produced by emulsion polymerization, emulsion. Emulsion PVC is characterized by wide molecular weight distribution, high content of impurities, high water absorption, by worse dielectric characteristics and the worse heat and light resistance compared with PVC-S.
PVC-E is applied in the production of gaskets, wallpaper, sealants, sheets, pipes and films for various purposes, artificial leather, latex glue, indoor awnings, metalloplastics, linoleum, furniture edging etc.
