PVC hard

PVC-U is a plasticizer-free PVC with good chemical resistance and processing properties. PVC offers a combination of excellent properties such as high strength and stiffness.

High strength and stiffness
Very good chemical resistance
Flame-retardant, self-extinguishing after removal of the flame
Very good electrical insulation properties
High resistance to acids, alkalis and saline solutions
Can be processed by welding, thermoforming and adhesion




The range of possible applications is huge: Hard PVC has very good chemical resistance, is suitable for outdoor use and is flame-retardant in accordance with DIN 4102 B1.
PVC has high resistance to acids, alkalis and saline solutions and is normally impact resistant. PVC also has good welding and bonding properties. PVC is flame-retardant and meets the requirements for classification in fire class B1 in accordance with DIN 4102 (1 – 4 mm). PVC has very good heat distortion resistance and good processing properties.


PVC can be processed with conventional machines and tools. PVC can be processed in numerous ways, e.g. turning, milling, sawing, drilling, punching, welding, cold bending, cold forming, printing.
