Durostone® composite fasteners are used in technical fields that have high demands on electrical, chemical and thermal properties. Durostone® frp fasteners are based on glass fibre reinforced epoxy or polyester resin Systems with special additives and a special structure.
Compared to steel composite fasteners made of Durostone® are:
EPR S5/EPR S7
High quality grade for use in chemical and maritime applications; particularly resistant to aggressive fluids – resists temperatures up to 180 °C.
Durostone® EPR S6 is a special for frp threaded rods developed epoxy high pressure laminate with outstanding technical properties; flame-resistant (V0 according to UL 94)
Durostone® UPR S19 is a threaded rod made of unsaturated polyester resin and glass fibres using the Sheet-Molding-Compound-Technology (SMC). The special polyester grade fulfills high dielectric requirements, is artial discharge free up to high electric field strength and has a high tracking resistance CTI 600.
Special quality for use when mechanical requirements are less critical. The frp threaded rods grade, VEG-Z, is produced from pultruded sections of unidirectional reinforced vinylester resin. Grade for use in chemical applications.
EPR S1/EPM 203
Standard grade for use electrical, maritime and mechanical applications; resists temperatures up to 180 °C.
Durostone® frp threaded rods, bolts and nuts are used in:
