Hydroxyl An Kashe Polybutadiene
Hydroxyl-terminated polybutadiene (HTPB) wani nau'i ne na roba na ruwa tare da nauyin kwayoyin halitta daban-daban (kimanin 1500-10,000 g / mol) da babban matakin aiki mai aiki.Ruwan roba yana da ƙayyadaddun haɗe-haɗe na kaddarorin ciki har da ƙananan zafin canjin gilashin, ƙarancin zafin jiki, ƙarfin ɗaukar nauyi mai ƙarfi, da ingantaccen iya kwarara.An yi amfani da su sosai a cikin mannewa, sutura, sutura, magani, da kuma kayan aiki masu kuzari.
HTPB ruwa ne mai jujjuyawa mai launi mai kama da takarda kakin zuma da danko mai kama da syrup na masara.Kaddarorin sun bambanta saboda HTPB cakuɗe ne maimakon fili mai tsafta, kuma an ƙera shi don biyan takamaiman bukatun abokan ciniki.
