Pultruded Glass Fibre Tubes made from E glass fibres that are drawn continuously through a die (more information see R&G eWiki). This production method causes the fibres to be oriented unidirectionally, i.e. along the length of the pultruded form. The result is a high fibre volume fraction of approx. 60 % with a very low air voids content.
Heat distortion temperature: 120 °C
