He aha kaʻokoʻa ma waena o ka pu a me ka rubber:
1. Nā kumuwaiwai likeʻole
ʻO nā lāʻau lapaʻau lāʻau i hanaʻia e nā'ōpala; Ua hanaʻiaʻo Pu i nā pāʻani pāʻani o Synthetic.

3.ʻO ka manaʻo likeʻole o ka hoʻohanaʻana
ʻO nā lāʻau Sghber i loaʻa ka paʻakikī; Ua hanaʻia nā kiʻi Fatballs i kaʻili synthetic, eʻoluʻolu loa i nā'ōlelo a ka elasticity a me ka manaʻo.
4. Nā kumukūʻai likeʻole
ʻO nā mea pāʻani backballs e pili ana a kūpono hoʻi i nā keiki a me nāʻoliʻoli; ʻO nā kiʻi Fatballs e pili ana i nā kumukūʻai kūpono a kūpono no nā mea hoʻomaka a me nā mea pāʻani a me ke aloha.

Ua loaʻaʻo Rubber basketball kiʻekiʻe elasticity a me nā modulus haʻahaʻa haʻahaʻa. ʻO ka maʻamau ka mea e elingation nui loa ma waena o 1 a me 9.8MPPA. Hiki i ka Ellingation ke kiʻekiʻe e like me ka 1000%. Ke hōʻike nei ia i nā hiʻohiʻona hou a hiki ke hoʻohanaʻia ma kahi ākea ākea o nā hōʻailona (- elastic i loko o 50 a 150 ℃).
Ka viscoolasticty o kahi basketball. He kino stocber he kino viscoolastic. Ma muli o ke ola o nā pūʻali ma waena o nā macromolecules, ua hoʻopilikiaʻia nā'ōpala ma nā pūʻali koa o waho.
