Glass epoxy tubes
Characteristics: The glass epoxy tubes are made from modified glass fabric as a basis and epoxy resin as a binder. This tubes have very good mechanical and electrical properties at high huminidy and mechanical strenght at higher temperatures.
Dimensions: The tubes are produced from inside diameter 5,2 mm. The wall thickness is from 2 mm. The tube length is 1050 mm.
