PBT vs PET: Molecular Structure, Crystallization Behavior and Modification Strategies
From engineering plastics and precision injection molding to modified polyester fibers, films and packaging Executive Summary Polybutylene terephthalate (PBT) and polyethylene terephthalate (PET) belong to the same family of aromatic polyesters, but their molecular structures give them significantly different crystallization and processing behavior. The key difference is the glycol component: PET is based on ethylene […]
