- PVC pipes for cable sewerage STIGMA EZ – Materials
Pipes and fittings are made of unplasticized polyvinyl chloride (PVC-U), which is a thoroughly tested material as it has been used successfully for many years in various pipelines. Various additives (lubricants, pigments, stabilizers) are added to the polyvinyl chloride to achieve the desired physical and chemical properties.
Pipes are made of raw material with the following characteristics:
density | 1,38 - 1,45 | g/cm³ |
---|---|---|
tensile strength | ≥ 45 | N/mm² |
softening point temperature (Vicat) | ≥ 79 | °C |
modulus of elasticity (E) | ≥ 3600 | N/mm² |
coefficient of linear thermal expansion | 0,8x10 | K¹ |
thermal conductivity coefficient (pri 23°C) | 0,16 | W/mK |
surface electrical resistance | >10¹² | Ω |
tensile breakdown strength | -200 | kV/cm |
