Polytetrahydrofuran is a white waxy solid that is easily soluble in alcohols, esters, ketones, aromatic hydrocarbons and chlorinated hydrocarbons, but insoluble in aliphatic hydrocarbons and water. It turns into a transparent liquid when the temperature exceeds room temperature.

Apperance	White waxy solid that turns into a transparent liquid when the temperature exceeds room temperature.
Melting point	33-36ºC
Density	1g/mL (25ºC)
Vapor pressure	<0.01 mm Hg (25ºC)
Refractive index	n20/D 1.465
Flash point	>230ºF
Glass transition temperature	-76ºC

Polytetrahydrofuran is mainly used as the soft segment of segmented polyurethane or segmented polyether polyester. The segmented polyurethane rubber made from polytetrahydrofuran with an average molecular weight of 1000 can be used as tires, transmission belts, gaskets, etc.; it can also be used for coatings, artificial leather, films, etc. The segmented polyether polyester produced is a thermoplastic elastomer. Polytetrahydrofuran with an average molecular weight of 2000 can be used to make polyurethane elastic fibers.
