| Polymeg 650 |
 |
Polytetramethylene ether glycols(PTMEG) are produced by the polymerization of tetrahydrofuran(THF).
Polymeg polyols are components of thermoplastic and thermoset urethane elastomers, spandex fibers and polyether ester thermoplastic elastomers.
- Used in - Cast, TPU, Cope, Spandex
- Superior hydrolytic stability.
- High fungus resistance.
- Low temperature flexibility.
- Superior dynamic properties.
- Excellent abrasion resistance.
- High moisture vapor transmission.
- Good tear strength. |
