Detay:

Deskripsyon

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

Nouvo Aplikasyon pou Travay

Polytetrahydrofuran se sitou itilize kòm segman mou nan an poliyiretàn segmenté oswa polyetè polyester segmenté. Kaoutchou an poliyiretàn segmenté ki fèt ak polytetrahydrofuran ak yon pwa molekilè mwayèn nan 1000 ka itilize kòm kawotchou, senti transmisyon, garnitur, elatriye; li kapab tou itilize pou penti, kwi atifisyèl, fim, elatriye Polyether polyester segmenté pwodwi se yon elastomèr thermoplastique. Polytetrahydrofuran ak yon pwa molekilè mwayèn nan 2000 ka itilize pou fè fib elastik an poliyiretàn.
