Chapter 3 – PVC Sheets

● Rigid PVC

(density 1,4g/cm³, thickness range 0,8 – 30 mm)

● Chemical foamed PVC, mono layer,

called „Free Foam Sheet“

(density about 0.55 – 0,7 g/cm³, thickness range 1 – 32 mm)

● Chemical foamed PVC with rigid layers,

coextruded,

called „Coex-Sheet“

(thickness range 2 – 12mm)

Rigid PVC Sheets: High hardness of surface (Shore D) Very good mechanical features, for example stiffness Corrosion-resistant Flame retarding Smooth surface Transparent sheets are possible

Further Advantages of Foamed PVC Sheet: Saving of material Still higher stiffness Workable like wood Less heat conduction Effect of absorbing vibrations
