Āhuatanga
Ko te hua parakore he karaihe kore tae, kaore he kakara. He ngawari te whakarewa i roto i te benzene, te chloroform (230g/L), te acetone (80g/L, te waro disulfide me etahi atu whakarewa pararopi, he iti te wairewa i roto i te ether me te waihano (<10g/L), kaore i te wairewa i te wai (30mg/L), kua pirau ki te waikawa, he ma, he kowhai marama ranei te tae.
Mahi
Ko te rapa whakatere TMTD he pai te whakatere tuarua mo nga momo whakatere momo thiazole. Ka taea hoki te whakamahi tahi me etahi atu accelerators hei whakatere mo nga matūriki colloidal vulcanization tonu. I te nuinga o te wa, ka taea hoki te whakamahi tahi me te whakatere MBT(M). He rite te ahua o te vulcanization o te rapa butyl. Ko te whakatere ka whakamahia te nuinga ki te hanga i nga potae, nga ngongo o roto, nga hu rapa, nga taonga rongoa, nga taura, nga hua rapa ahumahi, me etahi atu ka whakamahia hei patu me te ngarara i roto i nga mahi ahuwhenua, ka taea hoki te whakamahi hei taapiri hinu.
