A recently developed PE-RT type mat

A recently developed PE-RT type material still offers higher long-term strength at hightemperature and further improved processability, for example in larger diameter cooling waterpipes in power plants. Pipes based on these materials can be connected via heat fusion weldingor by the use of mechanical fittings. Furthermore, this material can be used in industrialapplications, where its temperature resistance may limit traditional Polyethylene and metallicmaterials often suffer from corrosion. The excellent weldability of these materials provides variousopportunities to connect even larger dimension pipes in industrial applications, an example of thisbeing the use in multi-layer structured oil pipelines onshore and offshore.This paper presents the material science and product design concepts that govern the high longterm hydrostatic strength at high temperatures. By controlling the molecular structure, the meltrheology and solid-state properties can be influenced, which results in a unique balance ofprocessability and hydrostatic strength.Also discussed are the product features and benefits of PE-RT materials. The paper showsexamples of the application range for this type of product, using applications in the domesticpipes market as a reference
