PBT (Polybutylene Terephthalate)

As products become miniaturized and the demand on materials to perform at increasingly thin sections becomes greater, plastic suppliers are looking to create materials to facilitate this trend, while still giving the torsional strength that consumers have come to expect from high quality products.

Polybutylene terephthalate (PBT) is a tough engineering polyester belonging to the same family as PET. Its main performance characteristic is its high strength and stiffness. Another major benefit is its versatility due to the grades in which it is available and also the range of fillers and reinforcements that it can be moulded with. As a stiff material, PBT has none of the flimsiness associated with some of the commodity ...
