Hytrel® is a unique TPC-ET which provides the flexibility of rubbers, the strength of plastics and the processability of thermoplastics. This incredible combination of features makes Hytrel® the material for choice for wire and cable applications in the consumer, automotive, electronic, industrial and construction sectors.
Hytrel® is perfectly suited to wire and cable applications because of its inherent combination of properties which harness the flexibility of rubbers and the strength and durability of plastics:
Hytrel® is a first-choice material for optical fibre tight buffers and mini loose tubes and provides a wide range of application benefits that help to protect the fibre from mechanical and environmental damage.
Its innate properties also make it an ideal polymer for insulating and jacketing of offshore cabling, where Hytrel® is often chosen to provide a slimmer profile versus alternative chemistries. This enables the design of lighter cables, supporting weight and cost reduction, as well as easier routing through cramped spaces by utilising its tighter bend radius. The flex-fatigue properties of Hytrel® make it the material of choice for constant movement applications, such as robotics, coil cords, sensors and other industrial cable uses.
Against competing flexible polymer technologies, Hytrel® continues to offer excellent flexibility at sub-zero temperatures, where other chemistries tend to stiffen, lose their flexibility, and break.
The chart to the right demonstrates the stability of Hytrel® at low temperatures as opposed to TPU materials.
DuPont™ have expertly developed a range of concentrates which can further enhance the properties of Hytrel. This is particularly interesting for wire and cable applications.
