Xitlhokovetselo lexi xa xithekiniki kusuka eka Jiangsu Aokai xi kambisisa hilaha mahiselo yale hansi kumbe yale henhla ya sintering ya onhaka hakona lapi ra mahiselo yale henhla ya PTFE. Ku sintering yale hansi swisiya ti particles tinga n’oki, leswi endlaka leswaku ti micro-pores, weak coating-substrate bonding, swiphemu swo khwaxa, matimba ya kahle ya michini, xikan’we na milky opaque appearance. Ku hisa ngopfu swi hlohletela ku onhaka ka mahiselo ya PTFE, leswi humesaka ti pinholes, ti bubbles, brittleness, ku cinca ka muhlovo wotshuka kuya eka ntima, xikan’we naku humesa musi wa chefu. Swilo leswimbirhi leswi hundzeletiweke swi herisa ku hlangana, matirhelo yo ka ya nga namarheli, ku cinca-cinca, ku pfalela, na ku tshamiseka ka dimensional.
