Kayayyaki
Ruwan Roba-Random Carboxy Nitrile Butadiene Rubber (L-XNBR)
Kayayyaki da Amfani
L-XNBR samfurin roba ne na ruwa mai ɗauke da nitrile da ƙungiyoyin carboxyl a cikin babban sarkar. Ƙungiyar nitrile na iya samar da ƙaushi mai kyau, zafi, abrasion da kaddarorin mannewa, yayin da ƙungiyar carboxyl za ta iya amsawa tare da epoxy da amino kungiyoyin don warkewa.
Ana iya amfani dashi azaman gyare-gyare mai ƙarfi don epoxy da resins na phenolic da kuma wakili mai laushi don filastik filastik, kuma ana amfani dashi a cikin filayen bugu na rollers, like, coatings da adhesives.
