■ Neoprene (CR):
Polima e entsoeng ka ho polymerization ea emulsion ea monomer ea chloroprene. Molek'hule ena ea rabara e na le liathomo tsa chlorine, kahoo ha e bapisoa le rabara e meng ea merero e akaretsang: E na le anti-oxidation e ntle haholo, anti-ozone, e sa cheseng, e itimang ka mor'a mollo, e hanyetsa oli, e hanyetsa solvent, e hanyetsa asiti le alkali, le khanyetso ea botsofali le khase. Ho tiea hantle le melemo e meng.
✔ E loketse ho lekanya phallo ea metsi a pompo, metsi a indasteri, metsi a leoatle le mecha e meng ea phatlalatso.
■ Rabara ea polyurethane (PU):
E polimetsoa ka polyester (kapa polyether) le motsoako oa diisocyanamide lipid. E na le melemo ea ho ba thata haholo, matla a matle, ho tenyetseha ho hoholo, ho hanyetsa ho tsofala, ho hanyetsa botsofali, ho hanyetsa ozone, ho hanyetsa mahlaseli le ho tsamaisa motlakase hantle.
✔ E loketse ho lekanya phallo ea metsi a litšila joalo ka pulp le pulp ea ore.
■Polytetrafluoroethylene (P4-PTFE)
Ke polymer e lokisitsoeng ka ho polymerisa tetrafluoroethylene e le monomer. E tšoeu e boka, e bonaletsang, e hanyetsa mocheso, e hanyetsa serame, e ka sebelisoa mochesong oa -180 ~ 260°C nako e telele. Thepa ena e na le litšobotsi tsa ho hanyetsa asiti le alkali, ho hanyetsa li-solvents tse fapaneng tsa tlhaho, ho hanyetsa asiti e belang ea hydrochloric, asiti ea sulfuric, aqua regia, le ho bola ha alkali e matla.
✔ E ka sebelisoa bakeng sa asiti e senyang le mokelikeli oa letsoai la alkali.
■Propylene ea polyperfluoroethylene (F46-FEP)
E na le botsitso bo botle ba lik'hemik'hale le khanyetso e ikhethang ea mahlaseli, hammoho le ho se chese, thepa e ntle ea motlakase le ea mechini. Thepa ea eona ea lik'hemik'hale e lekana le polytetrafluoroethylene, ka matla a matla a ho hatella le a ho thapolla e betere ho feta polytetrafluoroethylene.
✔ E ka sebelisoa bakeng sa asiti e senyang le mokelikeli oa letsoai la alkali.
■Copolymer ea tetrafluoroethylene le perfluorocarbon ka vinyl ether (PFA)
Thepa ea lesela bakeng sa flowmeter ea electromagnetic e na le thepa e tšoanang ea lik'hemik'hale le F46 'me e na le matla a ho thapolla a betere ho feta F46.
✔E ka sebelisoa bakeng sa asiti e senyang le mokelikeli oa letsoai la alkali.
