PEByog qhov kub-resistant engineered thermoplastic uas ua tau zoo nyob rau hauv raug rau kub kub thiab tshuaj lom neeg ib puag ncig.Cov khoom no muaj peev xwm khaws tau nws lub cev thiab tiv taus qhov kub txog li 480 degrees F ua rau nws yog ib qho khoom siv zoo heev uas tsim nyog rau ntau yam kev siv xws li stainless-steel hloov nyob rau hauv ib puag ncig hnyav.Nws yog ib lub teeb yuag lwm txoj rau hlau thiab txhuas thiab muaj siab hnav tsis kam tsis muaj lubrication.
PTFEyog crystalline polymer nrog lub melting point ntawm txog 621 ° F (327 ° C).Qhov ceev yog 2.13-2.19 gm / cc.PTFE muaj qhov tshwj xeeb ua rau cov tshuaj lom neeg.Nws qhov dielectric tsis tu ncua (2.1) thiab qhov poob qis yog qhov qis thiab ruaj khov thoob plaws qhov kub thiab qhov ntau zaus.PTFE muaj cov cuab yeej siv tau zoo los ntawm qhov kub thiab txias ntawm 500 ° F (280 ° C) qhov kub thiab txias.Nws coefficient ntawm kev sib txhuam yog qis dua yuav luag txhua yam khoom siv.Nws kuj muaj cov pa oxygen siab.
Kev sib piv ntawm PEEK thiab Polymer PTFE / FEP Property Values
Khoom siv:
* PEEK: Bearings; Pumps; Piston Parts; Cable Insulation.*PTFE: Cabling kev daws teeb meem; Tsis yog lubricated bearings; O-rings; Foob; Capacitors; Semiconductor manufacturing; Kub kub hluav taws xob qhov chaw; Gaskets; Valve Cheebtsam.
Khoom siv:
*PEEK: Siab abrasion tsis kam; Tsawg noo noo nqus; Cov tshuaj tiv thaiv zoo heev; Tsawg coefficient ntawm kev sib txhuam; Cov yam ntxwv zoo heev; Machinability.*PTFE: Zoo heev dielectric zog; Inertness rau feem ntau cov tshuaj; kub kub thiab tshuaj tsis kam; Tsis tshua muaj coeffiecient ntawm kev sib txhuam; Zoo heev hluav taws xob tsis kam; xoom noo noo nqus; Resensitive rau lub zog zaus; Machinability.
