Polypropylene Block Copolymers (PP-B) have a long and successful track record as a material for non-pressure piping applications in Europe. Many PP sewage systems have now been in service for over 30 years and since the introduction of the new PP high Modulus (PP-HM) grades in the 1990’s, market growth has been remarkably high. The PP-B sewage pipe market in Asia and Middle East is now set for a similar strong growth to that witnessed in Europe. With the continued failure of concrete and asbestos cement sewage systems, there is a significant opportunity for plastic pipes to replace existing networks and improve the standard of life in Asia and the Middle East. This paper will underline the benefits and whole life value of PP-B compared to other materials, and highlight the growth and subsequent opportunities for plastic pipes in Asia and the Middle East.

The Cyclic Cracked Round Bar (CRB) Test has been applied to study the slow crack growth (SCG) resistance of virgin, recycled, and reprocessed PVC-U. This fracture mechanical test allows a quick ranking of the SCG resistance of PVC-U. A clear correlation between the K-value and the SCG resistance has been elaborated....

In the early fifties, the first Polyethylene for the use in pipes was produced. Since then, the use of Polyethylene piping systems has spread rapidly around the globe to serve in various applications. In order to demonstrate the versatility and benefits of PE100, several companies founded in 1999 an association...

In this study, it has been demonstrated that a 100 years service-lifetime for non-pressure sewage pipes, solid wall pipes and structured-wall pipes of PE and PP, can be expected provided some basic conditions are met. It has been demonstrated that the resistance to thermo-oxidative degradation of the applied...

Due to the combination of climate change impact, resulting in many regions of the world having a heavier and unpredictable rainfall, together with increased urbanization, the possibility for lower natural infiltration of the water into the soil has created a real challenge for storm water management systems. Forecast...
