Whakamahinga
He mea whakangawari te polyisobutene (kua hauwaihia).
Ko te Polyisobutylene, e kiia ana i ētahi wā ko te butyl rubber, i ētahi wā ko te PIB, he polymer vinyl. He tino rite tōna hanganga ki te polyethylene me te polypropylene, engari ko ngā waro katoa e whakakapia ana ki ngā rōpū methyl e rua. He mea hanga mai i te monomer isobutylene, mā te polymerization vinyl cationic.
He rapa hangai te Polyisobutylene, he elastomer rānei. He mea motuhake nā te mea koinei anake te rapa kāore e uru ki te hau. Arā, koinei anake te rapa ka taea te pupuri i te hau mō te wā roa. Kua kite pea koe ka papatahi ngā poihau i muri i ētahi rā. Nā te mea he mea hanga ki te polyisoprene, ehara i te mea e uru ki te hau. Nā te mea ka pupuri te polyisobutylene i te hau, ka whakamahia hei hanga i ngā mea pēnei i ngā ngongo o roto, ngā paparanga o ngā potae, me ngā papa o roto o ngā poitūkohu.
Te Tākai me te Tukunga
180KG/Pahu, kia rite rānei ki ngā whakaritenga a te kiritaki.
Nō ngā taonga noa, ā, ka taea te tuku mā te moana me te rangi
Te pupuri me te rokiroki
Te roa o te oranga: 24 marama mai i te rā i hangaia ai, i roto i te takai taketake kāore anō kia whakatuwheratia, rongoatia ki te wāhi matao, maroke, ā, kāore e taea te ārai i te rā tika, i te wai rānei.
Whare putunga hauhautanga, Whakamaroke pāmahana iti, Wehea mai i ngā waikura me ngā waikawa.
