POLYVINYLCHLORIDE
Polyvinylchloride (PVC)
Polyvinyl chloride (PVC) is an amorphous, usually colored standard thermoplastic which only becomes a usable hard plastic through a variety of chemical additives
PVC is one of the oldest and most widely used thermoplastics. The material is characterized above all by a good chemical resistance and a comparatively favorable price at a relatively high specific weight (approx. 1.4 g/cm3). Although PVC has a comparatively high mechanical strength, it is - due to the low continuous operating temperature of approx. 60°C - mostly only suitable for static applications.
Main features
- good chemical resistance
- good electrical insulation properties
- heat deflection temperature 70°C
Various grades of PVC are used as standard for components:
POLYTRON PVC (PVC-U)
is the standard version of rigid PVC (PVC-U) with the above-described poperties. The material is usually supplied in dark gray, but is also available in a variety of other colors as well as in a crystal clear (clear-transparent) version. > Data Sheet
POLYTRON PVC-HI (PVC-HI)
The addition of a toughness-enhancing modifier improves the fundamentally poor notched impact strength of PVC-U significantly, but, however, reduces the strength of the material at the same time.
POLYTRON PVC-C (PVC-C)
Chlorinated PVC has a higher temperature resistance than unmodified PVC-U. The heat defelction temperature, for example, increases by approx. 30% which means that the maximum operating temperature can be selected higher by approx. 15 to 20°C.
