Fire-retardant TPU for consumer electronics

Huntsman has developed a new fire-retardant, halogen-free TPU that complies with current safety standards for cable jacketing materials used in the IT and consumer electronics sector.

Complying with key criteria set out in the European RoHS directive and US VW1 standard, Irogran A95P5003DP is said to meet demand for a durable cabling material that is free from hazardous substances. Huntsman underlines that it is far safer in the event of a fire than conventional materials like PVC and brominated flame-retardants.

The material can be extruded at high speeds on conventional PVC processing equipment and has a good surface quality. This makes it ideal for use in both cable power systems and injection moulding for electronic devices including plasma screens, mobile phones, MP3 players, digital cameras and laptops.

Franz Michel, TPU Account Manager, Mid-Europe at Huntsman Polyurethanes said: “The European cabling market is evolving rapidly. New legislation is impacting on the materials and manufacturing techniques used in many sectors. In consumer electronics, many of the larger equipment producers have publicly committed to the elimination of PVC and BFR from cables.”

Huntsman had introduced the new material at Wire in Düsseldorf, Germany. At the fair experts from Huntsman also advised cable and wire specifiers about Good Manufacturing Pratice (GMP) in the food industry.

Introduced in 2008, GMP legislation states that plastic-based materials, likely to come into contact with food, must meet a certain standard of material composition and be produced in a specific way.

With many manufacturers that supply the food industry still needing to switch to GMP-compliant materials, Huntsman says, that it offers practical support to help them understand the impact of the directive, source the correct raw materials and implement compliant processes and procedures.
