Reinforced PBT suitable for electrics

Lanxess has developed a range of glass fiber reinforced polybutylene terephthalate (PBT) compounds for use in electrical and electronic assemblies.

According to the company, Pocan E material has a tracking resistance rating of 600 under the International Electrotechnical Commission’s (IEC) 60112 standard and meets the insulation requirements of IEC 60664-1.

“Previously, glass-fiber-reinforced PBT compounds with such high tracking resistance were not readily available on the market,” said Dr Claudia Schmid-Daehling, manager of PBT product development at Lanxess.

According to Dr Schmid-Daehling, the materials also have improved flowability, hydrolysis resistance, and flame-retardant properties and are suitable for coloring.

Compounds with a CTI A test score of 600 include Pocan B3215E, Pocan B3217E, and Pocan B3235E, reinforced with 10, 16, and 30% short glass fibers by weight, respectively.
