Pu Safety Khau Tib System
Pu Safety Khau Tib System
kuv NTRODUCTION
PU Safety khau-ib system yog siv los ua kev nyab xeeb khau outsoles thiab puab txhais qab xib. Nws yog polyester-raws li PU system khoom, muaj plaub yam, polyol, ISO, hardner thiab catalyst. Cov ua ntawm lub cev yog ob lub Cheebtsam. Lub catalyst, nyuaj, tshuab neeg saib xyuas thiab xim yuav tsum tau tov meej nrog lub polyol tivthaiv EXD-3270A, ces sib tov nrog ISO tivthaiv EXD-3119B ua zaum kawg wares.
