DSM unveils halogen-free PBT

A DSM Engineering Plastics product story
Edited by the Engineeringtalk editorial team Oct 15, 2008

DSM Engineering Plastics has released Arnite T-XG 510 halogen-free (HF) PBT.

This PBT grade has received VDE approval for electrical insulating materials and is particularly suited for components such as connectors in white goods applications.

Arnite T-XG 510 is an unfilled PBT, and has tested positively according to GWFI and GWIT on end products.

It uses a flame-retardant system that is free of halogens and red phosphorus, meeting environmental concerns.

The lower density of HF PBT compared with halogen-containing materials saves material, cost and weight.

PBT also has better dimensional stability than other moisture-absorbing materials.

Halogen-free Arnite XG was tested by VDE for various temperature ranges, material thicknesses and colours, before receiving official approval and certification.

It meets the IEC 60335-1 standard that specifies the requirements for unattended household appliances operating under high currents (>0.2A).

The requirements include a GWFI at 850C (IEC 60695-2-12) and a glow wire test at 750C on end products (IEC 60695-2-11 GWIT).
