Mpira Wamadzi - Carboxyl Terminated Nitrile Butadiene Rubber (CTBN)
Katundu ndi Ntchito
CTBN ndi mphira wa nitrile wamadzimadzi wokhala ndi magulu ogwira ntchito a carboxyl kumapeto kwa unyolo wa maselo, ndipo gulu la terminal carboxyl limatha kuchitapo kanthu ndi epoxy resin. Amagwiritsidwa ntchito kwambiri polimbitsa utomoni wa epoxy. Ikhoza kusinthidwa malinga ndi zofuna za makasitomala.
