HYTREL
HYTREL  is a patent polymer of DuPont. It is a block co-polymer, consisting of a hard (crystalline) segment of polybutylene terephthalateand a soft (amorphous) segment based on long chain glycol

The grades of Hytrel are grouped into four categories, by performance:

•	General purpose grades which exhibit versatile processing characteristics, are lowest in cost and are suitable for many applications

•	High-performance grades generally provide an extra margin of mechanical properties for the more demanding applications

•	Specialty grades provide special properties or processing characteristics for particular applications

•	Concentrates contain relatively high concentrations of specific property-enhancing additives for blending with other grades of Hytrel.

Uses of Hytrel

The excellent properties of Hytrel qualify it for a number of demanding applications where mechanical strength and durability are required in a flexible component. Examples include seals, belts, bushings, pump diaphragms, gears, protective boots, hose and tubing, springs, and impact-absorbing devices. In many of these applications, Hytrel allows a multipiece rubber, plastic, or even metal composite assembly to be replaced with a single part. For outdoor applications, Hytrel should be protected from ultraviolet (UV) attack. Some of the industries where Hytrel can already be found include: automotive, fluid power, electrical/ electronic, appliance and power tool, sporting goods, footwear, wire and cable (including fiber optics), furniture, and off-road transportation equipment. The potential for using Hytrel in other industries is limited only by one’s imagination.
