ʻO PU Elastomers kahi ʻano mea synthetic hou ma waena o ka lāʻau a me nā plastics.Hōʻike ʻia ia e ke kūpaʻa ʻaʻahu ikaika, ka laulā paʻakikī ākea, ka elasticity kiʻekiʻe, ka ukana kaumaha, ka ʻaila kūʻē, ka pale ozone a me ka ikaika haehae kiʻekiʻe.He mea waiwai nui ka ʻenehana i ka ʻoihana hou. Hana ʻia ka pale polyurethane me ka polyurethane elastomer, kūpono no ka lanahu, metallurgy, mālama ʻōpala a me nā ʻoihana ʻē aʻe, i hoʻohana nui ʻia no ka nānā ʻana i nā mea, dehydration, deintermediation a me nā mea ʻē aʻe.
