PolyTHF® - Polytetrahydrofuran
PolyTHF® is a colorless, clear liquid (lower molecular weights) or white, waxy solid at room temperature. It will melt to yield a colorless, 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.

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
BASF’s PolyTHF® is an important intermediate in manufacturing thermoplastic polyurethane elastomers.
These products are used for the manufacturing of highly abrasion-resistant and flexible hoses, films and cable sheatings.
Other applications include thermoplastic polyetheresters, polyetheramide and cast polyurethane elastomers, proven for example in their use for skateboard and inline skates wheels.
- low temperature flexibility
- superior resistance against microbes and fungus attack
- superior dynamic properties (minimum heat build-up)
- high reactivity (bi-functional primary alcohol)
- high tear strength
