Product Description
CBT® 100 resin melts to a water-like viscosity when heated, then polymerizes into the engineering thermoplastic polybutylene terephthalate (PBT). CBT 100 resin has a processing temperature range between 190-240°C (370-460°F) and will be available in both one and two-part systems. This resin is formulated for compounding, injection molding, nanocomposites, rotational molding and as carrier resin for color and filler concentrates.

CBT 100 resin has a melt temperature of 180°C (356°F). It is supplied in pellet form and does not require grinding for most rotational molding applications.
