EPDM rabha ndeye thermoset elastomers (rubber) classification, ukuwo PTFE iri ye thermoplastics.Ndokumbira utarise kuti zvinhu zviviri izvi zvine densities zvakanyanya.
EPDM rabha ndeye thermoset elastomer kana rubber zvinhu.Iyo ine yakanyatso kudzika density uye yakanyanya kupisa huwandu hunoenderana nezvimwe zvinhu zverabha.
PTFE inonzi fluoroplastic (fluorine-based thermoplastic).Inogona kuva nehupamhi hwepamusoro pakati pe thermoplastics.Uye zvakare, inogona kuve ine mwero yakakwira ductility uye yakaderera yakadzika tambo simba.
EPDM yakapfava uye inoita iri nani yekuisa chisimbiso zvinhu (inopindirana zvirinani nekushata kwepamusoro kupera).polymer yakaoma uye inotsvedza, iyo inogona kusimudza zvirinani mune ine simba kana abrasive application.Vese vari vaviri vaigona kuita hanya zvishoma nezvemvura yegungwa kubva pakurwisa kwemakemikari/corrosion maonero.
Tembiricha yekuora yePTFE i> 490°C (>910°F) uye zvinhu zvikuru zvekuora ihydrogen flouride gasi (inoora zvakanyanya) uye carbon dioxide.Izvo hazvina kukodzera kushandiswa kwazvinozosangana neacetone kana inopisa alkaline application.
Kana iwe uchida kuti zvikamu zvisimbise shandisa EPDM kana Natural rubber, iyo PTFE zvinhu haizovharike zvakanaka zvachose.Iyo yakaoma, asi yakasimba uye inodhura zvakanyanya asi kazhinji haizovharike pamwe neye elastomer.
PS: Bata isu kune PTFE yakapedza zvigadzirwa zvemahara sampuro
