Testing

Testing products improves their quality and safety.
Laboratory for Plastics Testing conducts a series of tests, the main of which are:

Go to order


Geometrical characteristics

Physicochemical testing

  • melt mass-flow rate (MFR)
  • volatile content
  • density
  • carbon black content
  • water absorption of thermal insulation

Hydrostatic pressure testing

  • resistance to internal pressure
  • resistance to internal pressure after application of squeeze-off
  • resistance to slow and rapid crack propagation

Thermal testing

  • change in length, appearance and shape of pipes after heating
  • degree of crosslinking
  • oxidation induction time (thermal stability)

Mechanical testing

  • elongation at break
  • tensile strength
  • ring stiffness
  • ring flexibility
  • impact resistance
  • resistance to abrasion
  • resistance to environmental impact
