Hytrel 7246is a 72 nom.
Shore D, containing non-discoloring stabilizer, plasticiser free, high performance resin for injection molding and extrusion, outstanding mechanical properties up to 120'C, excellent hydrocarbon resistance and low permeability.
Hytrel 7246 is used extensively as a wire coating for toughness, abrasion resistance and retractable memory characteristics as used in telephone cords.
It is also used in a variety of molded goods requiring Hytrel with maximum hardness and stiffness, such as seat belt retractor components, oil field and textile machinery parts. |

The properties of Hytrel polyester elastomer are intermediate between those of rubber and engineering plastics.
The key properties of Hytrel 7246 include:
- High load bearing capacity.
- Excellent resistance to creep.
- High service temperature.
- Excellent resistance to swell in oils, fuels, and aliphatic and aromatic solvents.
- Low fuel permeability solvents.
- Highly elastomeric within its design range without the use of plasticisers. |
