1. NBR (Nitrile Butadiene Roj Hmab)
NBR yog ib qho hluavtaws elastomer tsim los ntawm copolymerizing butadiene thiab acrylonitrile los ntawm emulsion polymerization. Nws muaj kev tiv thaiv zoo heev rau hnav, kub, thiab kev laus, ua haujlwm zoo dua qub roj hmab hauv cov roj- hais txog kev siv. Nws yog dav siv nyob rau hauv cov khoom raug rau roj av-raws li hydraulic roj, lubricants, fuels, thiab kerosene.
2. VMQ (Silicone Rubber)
Silicone roj hmab yog tsim los ntawm cov pob txha ntawm silicon-oxygen (–Si–O–Si–) cov ntawv cog lus nrog cov organic sab pawg. Nws ua kom pom kev ruaj ntseg thermal zoo thiab ntev - lub sij hawm kev laus tiv thaiv. VMQ tseem muab cov nplaim hluav taws zoo thiab muaj zog tiv thaiv cov roj thiab ntau yam tshuaj lom neeg, ua rau nws tsim nyog rau qhov kub thiab txias thiab xav tau ib puag ncig.
3. FKM (Fluoroelastomer)
FKM yog ib qho kev ua haujlwm siab -elastomer uas muaj fluorine atoms hauv nws cov qauv molecular. Nws paub zoo txog nws qhov tshwj xeeb tiv thaiv tshav kub, ozone, hydraulic kua, thiab tshuaj lom neeg, ua rau nws zoo tagnrho rau kev ua haujlwm hnyav.
4. EPDM (Ethylene Propylene Diene Monomer)
EPDM yog terpolymer ntawm ethylene, propylene, thiab ib qho me me ntawm diene. Nws nta zoo heev tiv thaiv ozone, huab cua, thiab ntau yam corrosive, nrog rau zoo elasticity. Nws cov xim ntuj yog lub teeb beige, thiab nws feem ntau siv rau sab nraum zoov thiab siv tshuaj lom neeg siv.
5. PTFE (Polytetrafluoroethylene)
PTFE yog fluoropolymer ua los ntawm tetrafluoroethylene. Nws yog chemically inert thiab resistant rau corrosion, muab zoo sealing kev ua tau zoo, tsis tshua muaj kev sib txhuam, tsis yog -stick zog, hluav taws xob rwb thaiv tsev, superior aging kuj, thiab zoo heev ua hauj lwm nyob rau hauv ib tug dav kub ntau yam.
