Kafotokozedwe ka magwiridwe antchito: Zinthu zopangidwa ndi zinthu zosiyanasiyana zapamwamba zomwe zimatumizidwa kunja monga mphira wa ufa wa nitrile ndi graphite yochokera kunja.

Rabara ya nitrile yaufa ndi chosinthira chopangidwa kuchokera ku zida za polima.Ili ndi digiri yayikulu yogwirizana ndi ma phenolic resins.Ndiko kukonza kokwanira ndi ma friction pair ndikukhazikika kwa friction coefficient.

Monga elastomer, imakhala ndi mphamvu yabwino yolimbikitsira, imathandizira kukana kwa chinthucho, imachepetsa kuvala ndi kuuma kwa chinthucho, ndikuwonjezera chitonthozo cha chinthucho.

Lilinso ndi makhalidwe otsika enieni yokoka, mkulu kutentha kukana, palibe phokoso ndipo palibe kuipitsa.Ndiwo mphira wabwino kwambiri womatira pamakampani opanga mikangano.Ndizoyenera kugwiritsa ntchito galimoto m'misewu yosiyanasiyana.
