DSM Engineering Plastics, The Netherlands, a business group forming part of DSM�s Performance Materials cluster, provides the wire and cable industry with polyamides, polyesters, polycarbonate, as well as extrudable adhesive resins and ultra high-modular polyethylene. In addition to its existing family of Arnitel� copolyether-ester and copolyester-ester elastomeric wire coating materials, the company has developed and introduced new grades for this segment, that comprise:
- Arnitel U grades provide temperature resistance of 3,000 hours at 160�C, with peak temperatures up to 200�C, and is suitable for robotic, electric motor and similar applications;
- Arnitel P grades exhibit good flexibility at low temperatures (as low as -40�C);
- Arnitel E grades meet food and medical contact standards.
Masterbatches can be used not only for colour but also for enhanced resistance to UV, heat and hydrolysis, as well as flame-retardancy, including halogen-free systems. The Arnitel series provides superior resistance to repetitive deformation and fatigue, especially important in robotics. The material, available in a wide range of modulus and viscosity levels, shows good chemical resistance to oils, other hydrocarbons and most chemicals used in cars and industry. Its good electrical properties ensure outstanding dielectric behaviours. Furthermore, processing of Arnitel grades is measurably easier than with TPUs or fluoroelastomers, the company claims.
