Lub ntiaj teb no polyimide kev lag luam yuav tsum loj hlob ntawm ib tug compound txhua xyoo kev loj hlob tus nqi (CAGR) ntawm 5.9% los ntawm 2022 mus rau 2030.Lub polyimide kev lag luam yog loj hlob vim hais tias qhov kev thov nce rau polyimide nyob rau hauv ntau yam sectors, xws li electronics, aerospace, thiab kev kho mob:

Polyimide zaj duab xis yog siv los thaiv qhov chaw thiab xaim hauv cov khoom siv hluav taws xob, xws li ntse- xov tooj thiab nws pib- txawb. Qhov kev thov loj zuj zus rau cov lus qhia hloov pauv, hloov pauv hnub ci, thiab cov ntawv luam tawm yooj yim yog tsav lub khw.

• Flexible printed circuits (FPCs) : Polyimide yog siv los ua ib zaj duab xis substrate rau hloov tau tooj liab -clad laminates (FCCL), uas yog siv los ua FPCs. FPCs ua nrog polyimide yog qhov zoo dua li cov ntawv luam tawm tsis zoo (PCBs) thiab siv rau hauv cov khoom siv tes tuav thiab hnav.
• Flexible cables : Polyimide yog siv nyob rau hauv cov ntaub ntawv hloov tau yooj yim, xws li cov cable uas txuas lub laptop cov zaub rau nws lub ntsiab logic board.
• Insulating zaj duab xis : Polyimide yog siv los ua ib zaj duab xis insulating ntawm hlau nplaum hlau.
• Lub cev muaj zog coils : Polyimide yog siv rau lub cev muaj zog coils.
• Hlau txheej : Polyimide yog siv rau hlau txheej.
• Semiconductors : Polyimide yog siv rau dielectric / passivation txheej rau semiconductors.

Polyimide yog siv nyob rau hauv kev lag luam hluav taws xob vim nws muaj ntau yam zoo, xws li: siab thermal stability, mechanical zog, chemical resistance, thiab zoo dielectric thiab insulating zog.

Polyimide films yog siv nyob rau hauv aerospace vim lawv cov cua kub tsis kam, hluav taws xob rwb thaiv tsev, thiab siab zog.

Polyimide yog cov khoom siv ntau yam nrog ntau yam siv hauv kev lag luam aerospace, suav nrog:

• Rwb thaiv tsev: Polyimide yog siv rau hauv rwb thaiv tsev rau aerospace xov hlau, avionics, davhlau tswj, thiab navigation.
• Cov yam ntxwv ntawm cov khoom: Polyimide yog siv los ua cov khoom siv, cov ntsaws ruaj ruaj, thiab gaskets rau lub dav hlau.
• Cav vaj tse: Polyimide yog siv nyob rau hauv aerospace cav vaj tse.
• High -kub nplaum: Polyimide yog siv los ua lub siab -kub nplaum hauv kev lag luam semiconductor.
• Cov pa roj carbon fiber ntau: Polyimide carbon fiber composites yog siv nyob rau hauv uas tsis yog - thauj khoom cov qauv hauv cov dav hlau, riam phom systems, thiab chaw tsheb.

Polyimide yog ib qho polymer uas muaj ntau yam khoom zoo, xws li:

• Thermal stability : Polyimide tuaj yeem tiv taus qhov kub thiab txias, xws li nyob ze -270℃mus rau saum 400 degree.
• Tshuaj tiv thaiv : Polyimide tiv taus cov tshuaj lom neeg thiab cov kuab tshuaj organic.
• Dimensional stability : Polyimide tuav nws cov duab thiab qhov loj ntawm qhov dav ntawm qhov kub thiab txias.
• Hluav taws xob rwb thaiv tsev : Polyimide yog ib qho hluav taws xob zoo heev.
• Tsawg dielectric tsis tu ncua : Polyimide muaj qhov dielectric tsis tu ncua.

NASA's Langley Research Center tau tsim siab -kub nplaum siv polyimide rau Composites rau Advanced Space Transportation Systems (CASTS) thiab Supersonic Cruise Research (SCR).

Polyimide yog thermoset yas nrog ntau daim ntawv thov hauv kev lag luam kho mob, suav nrog:

Kev kho mob tubing

Polyimide tubing yog siv nyob rau hauv ntau yam khoom siv kho mob thiab kev siv, xws li vascular catheters, vim nws cov tshuaj tsis haum, yooj, thiab tawg tsis kam.

Kev cog hniav

Polyimide yog thawj cov khoom siv polymeric rau ntau daim ntawv thov kev cog qoob loo, tshwj xeeb tshaj yog neural implants. Nws biocompatibility txhais tau tias nws ua rau cov ntaub so ntswg me me thaum cog rau hauv lub cev.

Lwm daim ntawv thov kev kho mob

Polyimide kuj tseem siv tau rau hauv cov hlab plawv catheters, cov khoom siv rov qab, thawb lub nplhaib, cov hlua khi, angioplasty, stent xa cov cuab yeej, cov khoom siv paj hlwb, kev siv hluav taws xob insulator, thiab cov tshuab xa tshuaj.

Polyimide films yog siv nyob rau hauv kev kho mob kev lag luam vim lawv zoo tensile zog thiab kub kam rau ua.
