New England Ropes T- 900 Technora/Dyneema
New England T-900 Braided Rope features a unique core of blended Dyneema SK75 and Technora with a durable polyester cover. Bringing the best characteristics from each core fiber, T-900 has virtually no creep or stretch, has great resistance to flexing fatigue and abrasion, is light weight, and has zero moisture pick up. Easy to handle, T-900 is a firm line that holds wells in the clutches and does not hockle or develop meat hooks like wire does. T-900 improves overall performance with easy handling, weight savings aloft, and extremely low stretch. Highly recommended for halyard replacements.

Very little degradation from sunlight. Can be used outside over long term if inspected regularly.
Polyester has good resistance to most chemicals except 95% sulfuric acid and strong alkalines at boil. HMPE has good resistance to most minerals, organics, acids, and weak alkalines. HMPE also has excellent resistance to bleaches and other oxidizing agents and to most solvents.
Polyester melts at 480°F with progressive strength loss above 300°F. HMPE melts at 300°F with progressive strength loss above 150°F. Technora melts at 1200' F.
Good resistance to the passage of electrical current. However, dirt, surface contaminants, water entrapment, and the like can significantly affect dielectric properties. Extreme caution should be exercised any time a rope is in the proximity of live circuits.
Recommended sheave diameter to rope diameter is 8:1.
No blanket safe working load (SWL) recommendations can be made for any line because SWL's must be calculated based on application, conditions of use, and potential danger to personnel among other considerations. It is recommended that the end user establish working loads and safety factors based on best practices established by the end user's industry; by professional judgment and personal experience; and after thorough assessment of all risks. The SWL is a guideline for the use of a rope in good condition for non-critical applications and should be reduced where life, limb, or valuable property is involved, or in cases of exceptional service such as shock loading, sustained loading, severe vibration, etc. The Cordage Institute specifies that the SWL of a rope shall be determined by dividing the Minimum Tensile Strength of the rope by a safety factor. The safety factor ranges from 5 to 12 for non-critical uses and is typically set at 15 for life lines.
