Cov Qauv EPDM ntsaws ruaj ruaj muag muag hauv cov tshuaj dawb, o hauv acetone thiab tawv nqaij hauv citric acid, ua kom muaj kev tsis txaus siab thaum ntxov thiab cov neeg tsis txaus siab. Ib tiam tshiab ntawmTrigger txauUa haujlwm rau Viton (FEPM) cov ntsaws ruaj ruaj uas ua kom elasticity thoob th 1-13, kub -20℃mus rau 80% thiab tshuaj lom neeg mus rau 30% naoh. Cov tshuaj fluorinated elastomer<3 % volume change after 1,000-hour immersion in 6 % sodium hypochlorite, compared with 18 % for EPDM, translating into a six-fold service-life extension for bleach-cleaner trigger sprayers.
Viton lub polar fluorine cov tshuaj fluorine ua rau muaj kev piam sij me me {0} aphhanol thiab isopropanol, ua kom lub tshuab methologle, ua kom lub}}}} Nyob rau hauv kev nrawm q {4 {}} lub hnub xenon xeem (ASTM D7869) Cov ntaub ntawv khaws cia 90% Rau Industre degreasers muaj d - ciam ntaub txau rau xoom tawg kom tau raws li cov hlua khi ntawm en 1276 thiab EN 14476 tshuaj tua kab mob.

A colour-coded grey gasket differentiates the Viton variant during incoming QC, while laser-etched "pH 1-13" on the shroud aids consumers in identifying chemical-resistant models on shelf. Cov nqi muag khoom muag muag tus nqi yog qhov coj los saib: USD 0.038 rau ib chav ntawm 100 k moq, them-rov qab tiav thaum lub suab poob los ntawm 0.5%.
Los ntawm cov suab nrov ruaj ntseg, viton ntim khoom tso cai tso cai rau lub raj mis yuav tsum tau rov qab ua lag luam hauv cov lag luam tu cov nkoj, txiav cov khib nyiab yas 25%. Lub foob tseem yog dawb ntawm PFOs thiab PFOA, kho kom haum nrog Upcoming EU ncav cuag cov tshuaj lom neeg ntawm perfluorinated tshuaj. Moulders recommend pairing the Viton seal with an all-PP trigger sprayer to create a mono-material package that passes ASTM D5511 landfill biodegradation protocols when bio-additive masterbatch is included.
