Insulating with TPU Huntsman Polyurethanes has developed a new fire-retardant, halogen-free thermoplastic polyurethane (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 meets demand for a durable cabling material that is free from hazardous substances. Far safer in the event of a fire than conventional materials like PVC and brominated flame-retardants, Irogran A95P5003DP is a low-smoke solution that is easy to process. Irogran A95P5003DP can be extruded at high speeds on existing PVC processing equipment and has a good surface quality. This makes it ideal for use in cable power systems. Also available from Huntsman are TPUs to suit automotive, telecommunication, automation and offshore applications. Huntsman’s TPUs can be used to encase cable and wire in highly flexible materials that meet the most stringent mechanical standards, can be easily transported, and provide robust protection against extreme environmental conditions. 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 vinyl plastic (PVC) and brominated flame-retardants (BFR) from

cables. These changes are driving manufacturers to develop long-term partnerships with trusted raw material suppliers that understand the challenges and can offer compliant, high-performance products that meet new mechanical, safety and environmental standards.”

New elastomers for wire and cable needs

Based on ultra-high molecular weight PVC, Sunprene elastomers from A Schulman possess many rubber-like qualities, while offering thermoplastic processing, recyclability, and cost effectiveness compared with thermoset EPDM rubber and traditional thermoplastic elastomers. As a result, they provide exceptional tear and abrasion resistance, high flex fatigue, and excellent low temperature brittleness. The materials can be customised to meet a broad range of performance requirements. “Sunprene Elastomers are a high-performance, economical alternative to thermoset EPDM rubber and traditional thermoplastic elastomers,” said Lee Pfaffle, business manager, engineered plastics of A Schulman. “On cost, processing and performance, Sunprene Elastomers are an excellent solution for a variety of industrial, speciality wire and cable, and heavy truck applications.” Sunprene Elastomers are available in two series. The first series is specifically formulated for extrusion applications and has hardness ranges from Shore 35A to 85A durometer, and a specific gravity range between 1.20 and 1.29. The other series, designed for both injection moulding and extrusion applications, has hardness ranges from Shore 57A to 65A Durometer, and a specific gravity range between 1.22 and 1.27.
