5. Mowhiti hiri rapa fluorosilicone FLS

Ko tōna mahi he whakakotahi i ngā āhuatanga pai rawa atu o te silicone me te rapa fluorine. He tino ātete hoki ki ngā whakarewa, ngā hinu wahie, ngā pāmahana teitei me te iti, me ngā hinu. Ka taea te tu atu i te mimiti o ngā matū tae atu ki te hāora, ngā whakarewa kei roto ngā hauwaiwaro kakara, me ngā whakarewa kei roto ngā hauwaiwaro. -50~200 °C te awhe pāmahana mahi noa.

6. Mowhiti hiri rapa EPDM EPDM

He ātete ki te wai, ki te matū, ki te ōzone, ā, ki te huarere hoki. He pai te mahi mō ngā mahi hiri e pā ana ki ngā waipiro me ngā ketone me te kohu wai pāmahana teitei. Ko te awhe pāmahana paerewa mō te mahi ko -55 ki te 150 °C.

7. Mowhiti hiri neoprene CR

He tino ātete ki te huarere me te rā. He ātete ki ngā waikawa kua whakaranua me ngā hinu whakahinuhinu silicone, ā, kāore e wehi i ngā hauhautanga pērā i te dichlorodifluoromethane me te ammonia. I tētahi atu taha, ka nui te horapa i roto i ngā hinu kohuke he iti ngā ira aniline. Mā ngā pāmahana iti ka māmā te whakatioata me te whakapakeke.
