Ultem® / PEI (polyetherimide)i-polymer ephezulu ye-amorphous enobushushu obugqwesileyo kunye nokumelana nomlilo (iphethe ukulinganisa ukutsha kwe-94-V-0) kunye nokukhutshwa komsi omncinci.Isebenza ngokuqhubekayo ukuya kwi-340 ° F, iyenza ibe phezulu kuneeplastiki zempahla ezifana neNylon kunye neDelrin®.
PTFEyaphuhliswa ekuqaleni ukuba isetyenziswe kwizixhobo ze-aerospace kodwa ngokukhawuleza yafumana ikhaya kwizicelo zemizi-mveliso ezingenakubalwa.Iimpawu ezizodwa ze-PTFE ziquka: ukunganyanzeli kweekhemikhali (zimbalwa kakhulu iikhemikhali ezinokuyihlasela), i-coefficient ephantsi kakhulu yokukhuhlana (akukho nto inokubambelela kwizinto eziphathekayo ngawo nawaphi na amandla), ukumelana nobushushu obuphezulu (obukwazi ubushushu benkonzo ye-500 ° F) kwaye luncedo kakhulu ubume bobushushu obubandayo.
I-Ultem® / PEI (i-polyetherimide) i-polymer ephezulu ye-amorphous enobushushu obugqwesileyo kunye nokumelana nomlilo (iphethe ukulinganisa ukutsha kwe-94-V-0) kunye nokukhutshwa komsi omncinci.Isebenza ngokuqhubekayo ukuya kwi-340 ° F, iyenza ibe phezulu kuneeplastiki zempahla ezifana neNylon kunye neDelrin®.I-Ultem® sisisombululo esifanelekileyo kwizicelo ezifuna amandla aphezulu kunye nokukwazi ukumelana nokushisa okuphezulu.Imveliso iphinda ifanele izicelo ezifuna iipropati ze-dielectric ezihambelanayo kuluhlu olubanzi lwee-frequencies.I-Ultem® i-hydrolysis ixhathisa kwaye ixhathisa kakhulu kwizisombululo ze-acidic kwaye iyakwazi ukunyamezela imijikelezo ye-autoclaving ephindaphindiweyo, efana ne-sterilization yomphunga ephindaphindiweyo yezixhobo zonyango ezinokuphinda zisetyenziswe.I-Ultem® isetyenziswa ngokubanzi kwi-electronics ngenxa yokumelana kwayo ne-arc elungileyo kunye ne-dielectric constant.Ezinye izicelo eziqhelekileyo zibandakanya izixhobo zokuhlalutya kunye neenxalenye zesakhiwo ezifuna amandla aphezulu kunye nobungqongqo kumaqondo obushushu aphezulu.
