The laboratory
Our PVC compound is tested automatically every hour by our laboratory. These are the tests listed on our datasheets, and what each one tells you about your production.

Select a test to see what it measures.
Hardness sets how your part behaves: a gasket that seals, a sole that cushions, a fitting that holds its shape.
Density determines how many metres or parts you get from a 25 kg bag.
Tensile strength is the load the material carries before it breaks.
Elongation at break measures how far the material stretches: the flexibility of a cable or hose.
Heat stability is how long the compound withstands 200 °C without degrading: your processing margin.
The heat shock test checks that the material does not crack under sudden temperature changes.
Izod impact strength is the energy absorbed in an impact: how well a fitting or profile takes a knock.
Volume resistivity confirms the insulating power of cable compounds.
Oxygen index rates the fire performance of flame-retardant grades: the higher it is, the less the material sustains a flame.
