Cov khoom
Liquid Rubber-Hydroxyl Terminated butyronitrile Rubber (HTBN)
Khoom thiab Kev Siv
HTBN yog cov kua roj hmab nitrile nrog hydroxyl ua haujlwm pab pawg ntawm ob qho kawg ntawm cov saw molecular, nws muaj tib lub cev thiab tshuaj lom neeg zoo li nitrile roj hmab, thiab nws tuaj yeem kho nrog isocyanate curing agent nrog kev ua haujlwm zoo thiab kev ua haujlwm zoo.
Nws muaj cov roj ua haujlwm zoo, ua haujlwm kub, ua haujlwm tsis zoo thiab muaj zog adhesion. Feem ntau siv rau hauv cov nplaum, coatings, resin toughening tus neeg sawv cev, tuaj yeem txhim kho qhov toughness, adhesion thiab durability ntawm cov ntaub ntawv sib xyaw, roj thiab kub ua haujlwm.
