2. Electronics le Electrical Industry
Printed Circuit Boards (PCBs):
Resole resins cu PCBs chung i epoxy-phenolic laminates ah a biapi tukmi an si, a sangmi dielectric thazaang le a sangmi hmannak caah a tthawngmi a pek (tahchunhnak ah, 5G pehtlaihnak thilri).
Electric mei khamnak:
Molded phenolic thilri (tahchunhnak ah, switchgear thilri, terminal blocks) nih a ttha tukmi arc doh khawhnak le lumternak fek tein a umter, electric himnak caah UL 94 V-0 meikangh khawhnak phunglam a tlinh.
3. Mawtaw le thilri phurhnak lei
A tanglei thilri:
Phenolic resins cu clutch plate, brake pads, le transmission parts ah an hman hna, zeicahtiah lumnak (250°C tiang) le mechanical stress an tuar khawh caah a si. Tahchunhnak ah, European mawtaw sernak sehzung hna ah, phenolic-based hrialnak thilri nih riantuannak sang a ngeimi mawtaw hna ah brake fade a zorter.
A ritmi fonhmi:
Glass asiloah carbon fiber in fehtermi, phenolic composites cu truck cabin le tlanglawng chung ah a ritmi zorternak caah hman a si i cu lio ah cun a sining a tthatnak le meikanghnak himnak (tahchunhnak ah, tlanglawng phurhnak caah EN 45545-2 zulh).
4. Inn saknak le inn saknak thilri
Mei-a kham khomi thilthuam:
Phenolic resins cu a lum tukmi ah a huhphenhmi char layer ser awkah a kau i inn saknak (tahchunhnak ah, Asia ram i chawlehnak vancung inn sangpi) ah a rawkmi a tlaitertu intumescent rong ah an ser.
Insulation Panels:
Phenolic foam, 0.02 W/m·K lumnak thlen khawhnak a ngeimi cu innchungkhar le riantuannak hmun lumternak ah hman a si, polyurethane foam he tahchunh tikah mei a doh khawhnak a ttha deuh.
A hrenmi le a kharmi:
Phenolic-based adhesives nih thing, thir, le ceramics pawl kha saknak hmannak ah a peh hna (tahchunhnak ah, modular inn chung i laminated beams), caan saupi a fekmi le ti a doh khomi a pek.
5. Mipi nih an hmanmi thilri le a hleiin hmanmi thilri hna
Rawl chuannak le ti kholhnak thilri:
Molded phenolic resins nih a fekmi, lum a tuar khomi cabuai cung, ti kholhnak le ti kholhnak thilri pawl a ser. An cunglei a tlong lomi nih thurhnawmhnak le chemical pawl a tei khawh hna, cu nih cun chawlehnak rawldawr caah a ttha tukmi a siter hna.
Hnawmhnak thilri:
Resole resins nih a rawk khomi rawl (tahchunhnak ah, aluminium oxide, silicon carbide) kha sandpapers, grinding wheels, le cutting discs ah a hren hna, thing le thir sernak ah aa khatmi riantuan ning a hngalhter.

Quality & Zulhphung
Serning remh khawhnak:
Thilri cheukhat caah remh khawhmi:
Lungthawhnak a tuar khawhnak a sang: Vanlawng hmannak caah 300°C tiang thlalang thlennak lumnak (Tg).
Meikhu chuahnak tlawm: Khualtlawnnak le rili pawngkam caah remhmi tlukruannak (tahchunhnak ah, IMO FTPC Part 1 he aa tlakmi).

Caansau hmunhnak:
Cheukhat sernak ah bio-based phenol derivatives (eg, cashew nut shell liquid) hmangin sermi a si, cu nih cun petrochemicals cung i hngatchannak a zorter. Thazaang hmuh tthannak he khangh in hman tthan khawh a si.
Zeicah Kan Phenolic Resins Kan Thim?
Vanlawng caah mei a do khomi thilri, mawtaw caah a ttha ngaimi hnahnawhnak thilri, asiloah saknak caah a fekmi khamnak thilri na herh zongah, kan phenolic resins nih aa tluk lomi zumhawktlaknak an pek. Vawleicung thiamnak lei bawmhnak le North America, Europe le Asia ah thilchuahnak hmun hna he, na application nih a herhmi thilri pawl tlinter awkah novolac/resole cawhmi in a fekmi tlukruannak tiang—aa tlakmi a phichuak kan in pek.
