GEHR Plastics PVC-HI Polyvinylchloride, Impact Grade (discontinued **)
Categories:	Polymer; Thermoplastic; Vinyl (PVC); PVC, High Impact
Material Notes:	Polyvinyl chloride is a flame retardant material with an exceptional chemical resistance and also with lower stress cracking. PVC-U shows high mechanical strength, tensile strength and the continuous operating temperature is from -15°C to 60°C. It can also be easily solvent, cemented and welded. Properties include: High mechanical strength, tensile strength and hardness Good insulation properties for electronics High chemical resistance Self-extinguishing Low water absorption Easy to varnish and glue Low impact strength Limited weather resistance Applications include: Pumps and valve body Gaskets Bearing cages Pipe lines Hand pump pipes Brush basic body Parts in the dental medicine Seat strips Pipes for the mounting of kerfs Lamp box PVC-HI has increased impact strength at low temperatures.
