Polypropylene is the most widely used material for chemical- technical applications. Compared to PE, it displays greater rigidly particularly in the upper service temperature range (up to + 100 ° C). Its key characteristics also include excellent chemical resistance, good long term properties when exposed to various substances and high stress crack resistance.
There are two types of polypropylene: Homo polymers (PP-H) and copolymers (PP-C). PP-H consists entirely of a combination of propylene monomers and covers a service temperature range 0 °C to +100° C, PP-C features a chemical combination of propylene monomers and ethylene monomers, which increases the material’s impact strength at low temperature. PP-C covers a service temperature range from -20 °C to +80 °C and is less rigid from than PP-H.
DATA SHEET FOR PPH Pipe
- Considerable reduction in pressure loss due to improved hydraulic properties.
- Significantly lower risk of particle deposits and bacteria due to ultra-smooth surfaces.
- Potential cost-savings as a result of extended intervals between cleaning.
- Many different potential uses due to a service temperature range from 0° C to + 100 °C, depending on the application.
- Safe installation and assembly of pipe due to improved impact strength, even at low temperatures up to 0°
- Longer service life due to enhanced chemical resistance and minimized risk of stress cracks.
- Greater safety margin due to improved weld quality.
- Higher degree of safety when welding pipes in locations that are difficult to access.
