segmented polyurethane urea
1.05 as a clear polymer, or 1.20 as pigmented polymer 1.5% 390F/190C 437F/250C silicone oil with a metal stearate |
| Thermal performance | |
| - dry heat setting temperature/efficiency
- aqueous heat setting - boiling water - molding temperature |
188C-204C/370F-400F/60%-100%
104C-110C/220F-230F/80%-100% fiber retracts to original denier/modulus 196C-207C/385F-405F |
| Chemical resistance | |
| + good | aliphatic solvents
water solutions of acids above pH 3.0 and bases below pH 11.0 peroxygen bleaches saturated oils such as mineral oil non-phenolic dye carriers |
| - poor | aromatic solvents
acids at below pH 3.0 and bases above pH 11.0 chemicals containing active chlorine (sodium hypochlorite) unsaturated oils such as linseed, body oils, animal fats heavy metal salts (e.g. aluminum, chromium, zinc) |
| Environmental performance | |
| ELASPAN® fiber contains stabilizers that provide resistance to discoloration and eventual degradation by ultraviolet light, sunlight, and atmospheric pollutants (oxides of carbon, nitrogen or sulfur).
ELASPAN® fiber, as a polyurethane, burns when ignited by an external flame. It continues burning until oxygen is no longer available. |
