Roj Hmab Ua Kua - Carboxyl Terminated Nitrile Butadiene Roj Hmab (CTBN)
Cov Khoom thiab Kev Siv
CTBN yog cov roj hmab nitrile kua nrog cov pab pawg carboxyl ua haujlwm ntawm ob qho kawg ntawm cov saw hlau molecular, thiab pawg carboxyl kawg tuaj yeem ua rau muaj kev cuam tshuam nrog epoxy resin. Nws feem ntau yog siv rau kev ua kom epoxy resin tawv. Nws tuaj yeem hloov kho raws li cov neeg siv khoom xav tau.
