Uchungechunge lwe-PTMG/TDI

Incazelo emfushane:


  • Intengo ye-FOB:US $0.5 - 9,999 / Ucezu
  • Inani elincane le-oda:100 Isiqephu/Izingcezu
  • Ikhono Lokuhlinzeka:10000 Ucezu/Izingcezu Ngenyanga
  • izwe azalelwe kulo:China
  • uphawu lokuhweba:INOV
  • Imininingwane Yomkhiqizo

    Omaka bomkhiqizo

    ubulukhuni: ogwini A 75A - ogwini D 60D

    Umkhiqizo unezici zokusebenza okuhle, ububanzi obuqinile bobubanzi, ukuqina okuhle, ukumelana nokugqoka kanye nezakhiwo ezinhle kakhulu zemishini.

    Isetshenziselwa ukwenza imikhiqizo exubile ye-polyurethane elastomer efana nesondo lerabha elinwebekayo eliphakeme, ipuleti lesikrini, irola yerabha, indandatho yokuvala.
