Evonik Vestodur® CL2020 20% Glass Reinforced, Crosslinkable PBT Based Compound  (discontinued **)
Categories: Polymer; Thermoplastic; Polyester, TP; Polybutylene Terephthalate (PBT); Polybutylene Terephthalate (PBT), 20% Glass Fiber Filled
Material Notes: Description: VESTODUR CL2020 is a 20 % glass fiber reinforced, self-extinguishing compound for injection molding, based on modified polybutylene terephthalate (PBT).Moldings of VESTODUR CL2020 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 330 °C depending on the conditions. Therefore, crosslinked parts of VESTODURCL2020 can be used, for example, in common soldering processes in the electronic industry as surge soldering, gas phase soldering or IR soldering.
