A NOVEL TECHNOLOGY TO REDUCE PRODUCTION COSTS FOR POLYOLEFINE SEWERAGE PIPES BY PHYSICAL FOAMING

Posters

Polymer raw material costs for plastic pipe producers count for up to 80% of the total production costs. For non-pressure sewerage pipe application, one way to significantly reduce raw material consumption is to produce foam core multilayer pipes instead of solid wall products. A new development now allows to retrofit existing conventional extruder for PP foamcore pipe production using eco-friendly atmospheric gases.

The static test method of the Notched Ring Test (NRT) is compared with a fatigue testing method of Cracked Round Bar (CRB). Both methods are candidates for the classification of polyethylene (PE) materials with high resistance against Slow Crack Growth (SCG). In this paper tests of two PE 100 and two PE 100-RC...
