Neoprene (CR)
Neoprene, Polychloroprene e aofia ai le chloroprene monomer polymerization. Ina ua uma vulcanization, e lelei elasticity pa'u ma abrasion tetee. E tetee-insolation ma e lelei le teteʻe o le tau, tetee atu i le vevesi faʻalavelave, refrigerants, dilute acid, silicon ester lubricant, ae le tetee i le phosphate faasologa o suauu hydraulic. E faigofie ona faʻamaʻa ma faʻamaʻaʻaina i le maualalo o le vevela, vaivai le teuina o le mautu, ma le faʻalauteleina tele i le maualalo o le aniline o le suauu minerale. I le faʻaaogaina o le vevela o le - 50 ~ 150 tikeri.
Tulaga lelei:
Elasticity lelei ma lelei compression deformation, o le fua faatatau e leai se sulfur, o lea e matua faigofie ona faagaoioia. O lo'o i ai mea fa'aanti-manu ma fuala'au suau'u, o le a le a'afia i vaila'au fa'aituau, ga'o, suau'u, suau'u eseese, solvents, ma e iai fo'i mea fa'aanti- afi.
Fa'aletonu:
Aua le fautuaina e faʻaaoga i vailaʻau malosi, nitrohydrocarbons, esters, chloroform ma ketone ketone.
Talosaga:
Vaega pa'u po'o vaega fa'amaufa'ailoga fa'atasi ma le fa'aaisa R12, mea faigaluega a le fale. E talafeagai mo oloa pa'u e feso'ota'i sa'o ma le ea, susulu o le la, vaega o le osone, tetee atu i le afi ma le pala.
Tusi Faamaonia:
KTW W270 EN681-1,ACS,NSF61/372;WRAS,EC1935;FDA,EC1935;REACH,ROHS
O matou Fa'amanuiaga:
1. O pa'u ma mea fa'avaa o lo'o pipii mau.
2. Elasticity paʻu sili ona lelei ma seti faʻapipiʻi.
3. Tele nofoa mautu ma torque laʻititi, faʻamaufaʻailoga sili ona lelei ma faʻaofuofu teteʻe meatotino.
4. Fa'aaoga mea pa'u fa'ailoga fa'ava-o-malo ma fa'atinoga mautu.
5. Mea: CR, NR, SBR, NBR, EPDM, PTFE, Silicone, ma isi.
6. Faʻamaonia: NSF,SGS,KTW,FDA,ISO9001,ROHS,
7. maualuga / maualalo vevela tetee, suauu ma suauu tetee, lelei ea tightness ma isi.
8. Faʻagasologa ma faʻapipiʻiina e tusa ai ma ou manaʻoga.
9. Fa'aoga: Pulea o le vai, eletise, mea faigaluega a le fale, ta'avale, falema'i meafaigaluega, masini fale gaosimea & vaega, ma isi.
Mea Fa'afeso'ota'i Laupapa Filifiliga Vave:
| Mea | Talafeagai Temp. | Uiga |
| NBR |
-35℃~100℃ Vave -40℃~125℃ |
O le pa'u nitrile e lelei lona lava - fa'alauteleina meatotino, abrasion tete'e ma hydrocarbon - mea e tete'e. E mafai ona faʻaaogaina e avea o se mea lautele mo vai, vacuum, acid, masima, alkali, gaʻo, suauu, pata, suauʻu hydraulic, glycol, ma isi. E le mafai ona faʻaaogaina i nofoaga e pei o le acetone, ketone, nitrate, ma fluorinated hydrocarbons. |
| EPDM |
-40℃~135℃ Vave -50℃~150℃ |
Ethylene-propylene pa'u ose lelei lautele-fa'amoemoega pa'u gaosia e mafai ona fa'aogaina i vai vevela, meainu, mea susu, ketones, ava malosi, nitrates, ma glycerin, ae le o totonu o le hydrocarbon-su'u fa'avae, inorganics, po'o solvents.

| CR |
-35℃~100℃ Vave -40℃~125℃ |
Neoprene e faʻaaogaina i ala o faasalalauga e pei o acids, suauʻu, gaʻo, pata ma solvents ma e lelei le tetee i osofaʻiga. |
| FKM |
-20℃~180℃

O le Fluororubber o se suau'u fa'ameamea lelei-fa'asa'o, pa'u fa'apalapala fa'afefete mo le ga'o ga'o ma isi mea tau suau'u. E talafeagai mo le vai, suauu, ea, acid ma isi ala o faasalalauga, ae e le mafai ona faaaogaina mo le ausa, vai vevela pe mafiafia nai lo 82 °C. Alkali faiga. |
| SR | -70℃~200℃ | Silicone pa'u e tetee atu i le maualuga o le vevela, maualalo le vevela ma mea tau kemisi mautu, ma e masani ona faʻaaogaina i pisinisi e pei o le malosi malosi, vaivai alkali ma meaʻai. |
Mea fa'apitoa: pa'u nitrile carboxylated, pa'u nitrile hydrogenated, pala-ethylene tete'e-pa'u propylene, ausa-tefe fluoroelastomer, polyethylene chlorosulfonated |

Faia ma le sa'o atoatoa, o le PTFE + EPDM butterfly valve seat e fa'aalia ai le fa'aogaina lelei i luga o alaleo o vevela, ma le mautinoa e galue i totonu o le -50 i le +150 tikeri Celsius. O lenei fetuutuunai e avea o se filifiliga e le mafaatusalia mo faiga e manaomia ai le faatonutonuina o le vai, e aofia ai le inu, inu, ma le suavai leaga, ma mautinoa ai le lautele o le faaaogaina i galuega uma e lua o fale gaosi oloa ma le taulaga. , lea, pe a tuʻufaʻatasia ma le tomai faʻatekonolosi a le PTFE, e maua ai se faʻamaufaʻailoga sili ona umi e faʻaitiitia ai le lamatiaga o le tafe, ma faʻamautinoa ai le umi ma le faʻamaoni o le faʻaogaina o le valve. I le Sansheng Fluorine Plastics, matou te malamalama i le taua tele o le tausisia o le tafe e le faʻalavelaveina ma le puipuia mai le faʻaleagaina, o le mafuaʻaga lea ua faʻamalosia ai le matou PTFE + EPDM faʻapipiʻiina le nofoa valve butterfly e fetaui ma tulaga maualuga o le lelei ma le faʻatinoga. Pe mo mea fou faʻapipiʻi poʻo sui, o lenei nofoa valve e ofoina atu se fofo faigofie - e - faʻatinoina, faʻamautinoa le tuʻufaʻatasia lelei ma le faʻaogaina lelei i soʻo se vai felauaiga poʻo togafitiga.
