In general, Clear PVC is a transparent grade of PVC. It is rigid stiff and strong, has good impact strength, low moisture absorption and is inherently flame retardant. As with all PVC, it performs well when exposed to many salt solutions, acids and alkalis. It may be produced by Extrusion or Casting methods which results in differing mechanical properties. UV resistance of all PVC in general, is considered good; but it will degrade and age in time with prolonged exposure to UV rays which results in white blooming and discolouration. For Clear PVC this may not be desirable as its purpose is to be 'see-through', so for permanent outdoor applications UV stabilisers can be added to PVC, but this generally increases the cost and lead times.
PVC Sheet can be heat formed, hot gas welded and solvent cemented.
