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 teteʻeina o le tau, tetee atu i le vevesi faʻalavelave, refrigerants, dilute acid, silicon ester lubricant, ae le faʻasaʻo i 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 fa'afeso'ota'i sa'o ma le ea, susulu o le la, vaega o le ozone, tetee atu i le afi ma le pala.

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-faamoemoega pa'u gaosia e mafai ona fa'aoga i vai vevela, meainu, oloa susu, ketones, ava malosi, nitrates, ma glycerin, ae le o le hydrocarbon-suau'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 |

Fausia mai le pa'u fa'anatura sili ona lelei, o lo tatou Butterfly Valve Seat o lo'o fa'apipi'iina i meatotino fa'apitoa o le PTFE (Polytetrafluoroethylene) ma le EPDM (Ethylene Propylene Diene Monomer), o mea e ta'uta'ua mo lo latou maufetuuna'i ma agava'a fa'alelei. O le lanu uliuli, faʻalelei mamanu o le nofoa valve e le gata e faʻaalia ai lona malosi ae faʻapea foʻi lona faʻaogaina, ma avea ai ma filifiliga sili mo talosaga e aofia ai le vai, vai inu, vai inu, ma vai otaota. Pe e te galue i totonu o le pisinisi meaai ma meainu, togafitiga vai, poʻo soʻo se vaega e manaʻomia ai le pulea lelei o le suavai, o lenei oloa e faʻamaonia e faʻaleleia ai le faʻatinoga o lau faiga ma le umi o le ola. e amata mai i le -50 i le 150 tikeri Celsius. O lenei va'aiga lautele o le vevela e fa'amautinoa ai le fa'atinoina lelei i totonu o si'osi'omaga malulu ma vevela, e maua ai le filemu o le mafaufau mo enisinia ma fa'alapotopotoga. O le mama fa'amaufa'ailoga a le Bray butterfly valve, o se vaega taua o la matou oloa, ua mamanuina ma'oti e fa'amautinoa ai se fa'amaufa'ailoga mau, leak-fa'amaufa'ailoga, fa'aitiitia mana'oga tausiga ma fa'aumiumi le ola tautua o au va'a. I le Sansheng Fluorine Plastics, matou te malamalama i le taua o le faʻatumauina o se tafega ma faʻamautinoa le saogalemu ma le mama o au faʻasalalauga. O le matou Suiga o le PTFE + EPDM Butterfly Valve Seat o se faʻamaoniga o lo matou faʻamaoni i le tuʻuina atu o fofo e le gata ina ausia ae sili atu i tulaga faʻapisinisi. Fa'afeso'ota'i matou i aso nei e su'esu'e pe fa'apefea ona fa'ae'eina ea matou oloa le lelei ma le fa'amaoni o lau galuega.
