Khoom ntawm Polyimide Films

SOLVER POLYIMIDE | Updated: Sep 15, 2014

1. tawg ntho uas muaj ntxhiab polyimide los thermogravimetric tsom, decomposition pib kub no feem ntau rau ntawm 500 ℃. Ntawm ob tug los yog ob tug benzene anhydride thiab diphenyl amine synthesis ntawm polyimide, thermal decomposition kub txog 600 ℃, yog ib hom kab ntau tshaj hitherto polymer thermal stability.

2. polyimide yog huab tsis kub, tshuaj tua tsis xws li tsis ua - 269 ℃ nyob embrittlement helium kua.

3. polyimide nrog txhua yam khoom zoo heev, tensile ua tau cov unfilled uas muaj zog saum 100Mpa, nyias films ntawm polyimide (Kapton) ntau tshaj 170Mpa, thiab biphenyl polyimide (Upilex S) mus rau 400Mpa. Raws li yam xws li tshuab yas, elastic modulus mas 3 4Gpa fiber ntau tus yuav mus txog 200Gpa, raws li theoretical muab xam, ob benzene anhydride thiab ob benzene amine synthesis fiber ntau ncav 500Gpa, ntxiv mus rau cov fiber ntau xwb.

4. ntau hom polyimides yog tsis soluble organic cov kuab tshuaj, cov kua qaub stability nta, paub ntau yam tsawg kuj mus hydrolysis, no seemingly shortcomings kev kawm ua tus polyimide muaj ntau yam ntxwv txawv ntawm lwm cov kev kawm siab polymers, uas tau siv cov hydrolysis ntawm cov ntaub ntawv siv ob anhydride alkaline thiab ob amines, xws li Kapton zaj duab xis, lub qab npaum li 80% - 90%. Hloov cov qauv tseem yuav heev hydrolysis resistant hom, xws li kev muag zaub tuaj rau 120 ℃, 500 teev dej.

5. lub thermal expansion coefficient 2 * 10-5 mus rau 3 * 10-5 ℃, Guangcheng polyimide thermoplastic 3 * 10-5 ℃, biphenyl ntaus ntawv mus rau 10-6 ℃, hom neeg yuav mus txog 10-7 ℃.

6. polyimide nrog irradiation siab kuj, naam hauv 5 × 109 rad yoo electron irradiation ua tau ceev muaj 90%.

7. polyimide muaj dielectric zog, plaug fluorine dielectric tsis tu ncua yog 3.4 li, los yog cov cua, nanometer me me hauv cov polyimide, dispersed qhov dielectric tsi hloov yuav txo tau kom li 2.5. Dielectric tsi 10-3, qhov dielectric zog ntawm 100 300KV/hli Guangcheng thermoplastic polyimide 300KV/hli, ntim kuj ntawm 1017 Ω /cm. Cov khoom yeej tseem tswj ib theem siab dav kub ntau yam thiab ntau zaus.

8. polyimide yog qhov quenching txog polymer, cov uas tsis muaj tus nqi uas haus luamyeeb.

9. polyimide hauv siab nqus plua plav outgassing tsis tshua.

10. polyimide yog cov mob toxic, yuav muab siv rau qhov siv thiab ua tableware thiab cuab yeej siv kho mob, thiab tau txhiab zaus mas es ho. Muaj ntau tej polyimide tau zoo me compatibility, piv txwv, hauv cov ntshav compatibility xeem rau yam uas tsis yog tus mob hemolytic, cytotoxic hauv vitro thwmsim rau cov mob toxic.


  • Tuam txhab profile
    SOLVER POLYIMIDE founded rau lub kaum ib hlis 2010, yog ib lub chaw tsim tshuaj kev thiab qib high tech paus POLYIMIDE (PI) thiab cov khoom uas muaj lub npe "GOLDEN yas". SOLVER POLYIMIDE yog ib lub manufactures ntawm Thermoplastic Polyimide, Thermosetting Polyimide, hmoov Polyimide, Polyimide Pallet, Polyimide ua kua, Polyimide Profile, Polyimide Particle, Polyimide Monomer, Polyimide ua npuas ncauj , Cob polyimide, txheej Polyimide, Polyimide puas khoom, Polyimide siv lead ua kua tuab si lug no thiab hais txog. thermoplastic polyimide hoobkas, tuam txhab, theem muag tag nrho, muas, cov khoom. SOLVER POLYIMIDE polyimide yog ib yam kev kawm siab yam xws li tshuab yas. Nws tsis zoo xwb muaj thermal yav tom ntej, txhua yam, dielectric, stability seem, ua hauj corrosion thiab tawg los tiv thaiv kev, tab sis kuj muaj zoo machinability. Nws yuav tau zoo li tus los ntawm kev sib txawv xws li zoo li molding, extrusion, molding txhaj tshuaj thiab txhaj tshuaj....
