Durostone® UPM S13 LST

GFK-UP

Durostone® UPM S13 LST is a fiber-reinforced plastic with an exceptionally good behavior in fire. The flammability of plastics attains a particular value of FVO /> 1mm. Convinced by this plastic has a low toxicity and low smoke density, making this one of our Durostone specials. Moreover Durostone® UPM S13 LST meets requirement R11, hazard level HL3, for arc resistant insulation materials of EN 45545-2:2013.

Characteristics

  • SMC high-pressure laminate
  • Special polyester (UP) resin matrix reinforced with an e-glass roving mat
  • High mechanical strength
  • High dielectric strength
  • Flame retardant

Application Examples

Insulation hood for Durostone® pantographs

Durostone® UPM S13 LST consists of an unsaturated polyester resin with a glass mat reinforcement. The material meets the requirement R11, hazard level HL3, for arc resistant insulation materials of EN 45545-2:2013. It offers high strength both at room temperature and at higher temperatures. The density of 2.10 g/cm³ enables the production of lightweight components with high mechanical strength – for example, mounts on the bogie for pantographs (shoebeams), covers and spark extinguishing chambers.
