Tag nrho cov ntsaws ruaj ruaj yog ib qho kev lees paub kev hloov pauv ntawm cov khoom zoo PTFE gaskets, ntsaws ruaj ruaj, ntxhua khaub ncaws thiab insulators.
Tag nrho cov ntsaws ruaj ruaj muaj kev paub nyob rau hauv muab precision PTFE gaskets, seals, washers, thiab insulators rau ntau yam kev lag luam thiab kev siv.Polytetrafluoroethylene (PTFE) yog DuPont lub cim lag luam ntawm polymer.Nws yog ib qho hluavtaws fluoropolymer ntawm tetrafluoroethylene uas muaj cov pa roj carbon thiab fluorine tag nrho.Nws yog innately hydrophobic (repelling dej thiab dej uas muaj tshuaj) thiab muaj ib tug qis tshaj coefficients ntawm kev sib txhuam tawm tsam tej khoom.
PTFE muaj cov khoom zoo heev dielectric thiab muab thermal rwb thaiv tsev zoo nrog kev ua haujlwm kub ntawm -400 ° F txog 500 ° F.PTFE yog cov tshuaj tiv thaiv cov yas uas paub zoo tshaj plaws thiab tsis cuam tshuam los ntawm feem ntau cov kua dej corrosive, vapors, thiab gases.PTFE feem ntau muaj nyob rau hauv thicknesses spanning ntawm .002 "mus rau .250" tuab thiab conforms rau FDA thiab AMS specifications, ua rau nws tau txais kev kho mob thiab khoom noj khoom haus industries.
PTFE, tsis muaj polymer Gaskets
Virgin qib PTFE gaskets yog tsim los ntawm 100% cov ntaub ntawv ntshiab uas yog siv nyob rau hauv feem ntau daim ntaub ntawv.Nws yog mos heev thiab formable thiab feem ntau yog siv rau chemical resistant seals thiab gaskets.Nws yog tsim los ntawm cov neeg tsim khoom ncaj qha thiab tsis tau ua tiav rau hauv cov duab.Nws muaj lub siab tshaj plaws lub cev thiab hluav taws xob rwb thaiv tsev zog thiab muaj zog tiv thaiv creep (compression) nyob rau hauv load.Virgin qib PTFE tuaj yeem lees paub los ntawm nws cov xim dawb dua piv rau qib PTFE.
PTFE, puvpolymerGaskets
PTFE gaskets puv yog tsim los ntawm PTFE uas integrates additives thiab fillers nyob rau hauv thiaj li yuav txhim kho cov kev ua tau zoo ntawm lub gasket.Qhov no txhim kho lub peev xwm hnav thiab txhim kho nws qhov sib xyaw ua ke ntawm cov tshuaj lom neeg, lub cev thiab hluav taws xob.Filled polymer yog hom ntau tshaj plaws ntawm PTFE gasket rau kev lag luam siv vim nws nthuav tawm cov khoom siv dag zog zoo dua qub piv rau Virgin PTFE.Cov iav, carbon thiab fiber ntau yog cov khoom ntim uas raug siv los txhim kho lub zog ntawm lub gasket nyob ntawm daim ntawv thov.
PTFE, nthuav davpolymerGaskets
Expanded PTFE gasket khoom yog tsim los ntawm expanding Virgin PTFE siv cov txheej txheem uas tsim ib tug uniform thiab fibrillated microstructure nrog sib npaug tensile zog nyob rau hauv tag nrho cov lus qhia.Qhov no txhais tau hais tias nthuav dav polymer tsis muaj cov qauv tsis muaj zog lossis "grain".Txij li thaum tsis muaj additives yuav tsum tau, nthuav polymer kuj muaj cov tshuaj tiv thaiv tshwj xeeb ntawm Virgin polymer.Expanded PTFE yog ntau softer thiab ntau saj zawg zog tshaj li niaj zaus PTFE gaskets thiab yog li conforms yooj yim rau irregular thiab ntxhib nto.Cov khoom yog yooj yim rau compress thiab minimizes creep thiab txias txaus.
