Polybutylene terephthalate(PBT)

PBT, Polybutylene Terephthalate, belongs to the family of polyester thermoplastics. PBT is a semi-crystalline polymer used mainly in injection moulding for engineering applications.

Karanco is offering a wide range of PBT compounds and also blends with PET, PC and ASA.

PBT  grades are supplied in pellet form and packed in moisture proof 25 kg multi-layer bags. Other forms of packing like octabins and big-bags with PE or Aluminum in-liners are also available.

All packaging is tightly sealed and should be opened just before processing. It is also advised to be kept in dry environment below 50°C while protected from UV-light. In order to prevent condensation, packaging stored in cold areas should be allowed to warm up to room temperature before being opened.

Under normal conditions PBT is not a toxic and hazardous material. During processing, necessary preventive actions should be held in case of contact with polymer melt or inhalation of the gases. Processing temperatures above 300 °C should be avoided. Detailed safety information can be found in our material safety data sheets (MSDS).
