Lapa maoli
ʻO ka lāʻau lapaʻau maoli kahi ʻano molecular kiʻekiʻe kūlohelohe me ka polyisoprene ka mea nui. ʻO kāna kumu molekala (c5h8) n. ʻO 91% ~ 94% o kāna mau ʻāpana he hydrocarbons pulupulu (polyisoprene), a ʻo ke koena he mau mea lāʻau ʻole e like me ka protein, ka momona momona, ka lehu, ke kō, a me nā mea ʻē aʻe.
ʻO ke kūpaʻa ʻino
Loaʻa iā ia ka elasticity kiʻekiʻe a me ka plasticity liʻiliʻi ma ka lumi wela, a crystallize a paʻakikī i ka haʻahaʻa wela. Loaʻa iā ia ke kūpaʻa alkali maikaʻi, akā ʻaʻole ikaika ka ikaika o ka waikawa. ʻAʻole hiki ke hoʻoheheʻe ʻia i loko o ka wai, nā ketone haʻahaʻa a me nā ʻawaʻawa, a hiki ke pehu i nā solvents non-polar e like me ka chloroform a me ka carbon tetrachloride.
