Paʻa a i ʻole elastomeric nā mea maka i loko o ka lumi lumi, a hoʻomehana ʻia nā mea maka i ka wā o ka hana ʻana e hoʻohuli iā lākou i ka wai, nā wai hoʻoheheʻe.Hiki ke hoʻokaʻawale ʻia nā plastics i "thermoplastics" a me "thermosets" e like me kā lākou ʻano hana.
Hiki ke hoʻomehana ʻia a hana ʻia nā "Thermoplastics" i nā manawa he nui a hiki ke hana hou ʻia.He wai lākou e like me ka slime a he ʻano hehee mālie.ʻO nā thermoplastics maʻamau ka PE, PP, PVC, ABS, a me nā mea ʻē aʻe. Hoʻopaʻa paʻa mau nā thermosets i ka wā i wela ai a maʻalili.Hoʻokumu ke kaulahao molekala i nā paʻa kemika a lilo i hale paʻa, no laila inā e wela hou ʻia, ʻaʻole hiki ke hiki i kahi kūlana wai hoʻoheheʻe.ʻO nā epoxies a me nā rubbers nā laʻana o nā plastic thermoset.
Eia kekahi mau ʻano maʻamau a me nā kikoʻī o nā kaʻina hana plastik: ka hoʻolei ʻana i ka plastic (drop molding, coagulation molding, rotational molding), blow molding, plastic extrusion, plastic thermoforming (compression molding, vacuum forming), plastic injection molding, plastic Weld (friction). wiliwili, hoʻoheheʻe laser), hūaʻi plastik
