PVC

GEHR PVC-U®

Polyvinylchloride is rated self-extinguishing, has an exceptional chemical resistance and is easy to machine. PVC shows high mechanical strength, tensile strength and can be used in applications ranging in temperatures from +5 °F to +140 °F. With repeated UV exposure the material may change color and exhibit a slight increase in tensile strength as well as a slight decrease in impact strength. It can also be easily solvent cemented and welded.

Properties:

  • 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
  • increased impact strength
  • limited weather resistance

Applications:

Pumps and valve body, gaskets, bearings cages, pipe lines, hand lamp pipes, brush basic body, parts in the dental medicine, seat strips, profiles for cabin and fair construction, pipes for the mounting of kerfs, lamp box.

GEHR PVC Type II® (impact mod.)

Increased impact strength at low temperatures (-40 °F).

GEHR PVC Type I ELS® (electrically conductive)

PVC with improved electronical conductivity.
Volume resistivity ≤ 106 Ω
Surface resistivity ≤ 106 Ω

GEHR CPVC® 

  • high rigidity, strength and hardness at increased temperatures (+185 °F).
  • flash ignition temperature of +900 °F.
  • will not sustain burning
  • UL rated 94 V-0. It is homopolymer PVC that has been subjected to a chlorination reaction.
