PolyTHF® - Polytetrahydrofuran
PolyTHF® is a colourless, clear liquid (lower molecular weights) or white, waxy solid at room temperature. It will melt to yield a co lourless, clear liquid. It is soluble in many conventional organic solvents, partly infinitely mixable. It is practically insoluble in water.
PolyTHF® is also an important intermediate in manufacturing thermoplastic polyurethane elastomers (TPU). These products are used for highly abrasion-resistant and flexible hoses, films and cable sheathing. Other applications include thermo-plastic polyetheresters, polyetheramide and cast polyurethane elastomers, provenin their use for skateboard wheels and inline skates.
BASF delivers PolyTHF® in the following molecular weights:
- PolyTHF® 250
- PolyTHF® 1400
- PolyTHF® 650
- PolyTHF® 1800
- PolyTHF® 1000
- PolyTHF® 2000
PolyTHF® is a polymer created by linking a series of identical units (=monomers) together, thus forming a chain.
The unit is tetrahydrofuran (THF); water (H-O-H) caps the ends.
PolyTHF® is the key raw material used to produce spandex fibers.
It is a polymer which, depending on its molecular weight, solidifies between -15 and 30°C in a waxy-like manner.
PolyTHF® is integrated by further reactions into polymers with molecular weights of 40,000 and higher.
- Hydrolytic stability
- Microbial resistance
- Not allergenic
- Highabrasion resistance
