Cyclics CBT® 100 Thermoplastic Resin  (discontinued **)
Categories: Polymer; Thermoplastic; Polyester, TP; Polybutylene Terephthalate (PBT)

Material Notes: CBT® 100 resin melts to a water-like viscosity when heated, then polymerizes into the engineering thermoplastic resin polybutylene terephthalate (PBT). CBT 200 resin has a processing range between 190-240°C and is available in both one and two-part systems. CBT 100 resin is formulated for compounding, injection molding, nanocomposites, rotational molding, and as a carrier resin for color and concentrates.
