Engineering Thermoplastics
PC/PBT Blend — Polycarbonate / Polybutylene Terephthalate Blend
PC/PBT blends combine the excellent impact strength and heat resistance of PC with the good chemical resistance and lower moisture absorption of PBT. This blend offers enhanced toughness and better resistance to a wider range of chemicals compared to pure PC or ABS blends.
