Evonik Vestodur® CL2045 45% Glass Reinforced, Crosslinkable PBT Based Compound (discontinued **)
Categories:	Polymer; Thermoplastic; Polyester, TP; Polybutylene Terephthalate (PBT); Polybutylene Terephthalate (PBT), 50% Glass Fiber Filled
Material Notes:	Description: VESTODUR CL2045 is a 45 % glass fiber reinforced, self-extinguishing compound for injection molding, based on modified polybutylene terephthalate (PBT).Moldings of VESTODUR CL2045 can be crosslinked by high-energy radiation (ß- or ?-radiation) or heat. The radiation will not influence the mechanical properties significantly. The short-term heat resistance is increased up to 450 °C depending on the conditions. Therefore, crosslinked parts of VESTODURCL2045 can be used, for example, in common soldering processes in the electronic industry as surge soldering, gas phase soldering or IR soldering. The incorporated flame retardant is non-migrating and has no corrosive effects on metal inserts or neighboring metal parts. Laser marking with high contrast is possible.
