Mea hoʻopaʻa māmā hana kiʻekiʻe DB886
ʻO ka hōʻailona DB 886 he pūʻolo hoʻopaʻa UV hana kiʻekiʻe i hoʻolālā ʻia no nā ʻōnaehana polyurethane (e laʻa me TPU, CASE, RIM flexible foam applications). ʻO DB 866 maikaʻi loa i ka polyurethane thermoplastic (TPU). Hiki ke hoʻohana ʻia ka DB 866 i nā uhi polyurethane ma ka tarpaulin a me ka papahele a me ka ʻili synthetic. Hāʻawi nā noi DB 886 i ke kūpaʻa UV koʻikoʻi i nā ʻōnaehana polyurethane. ʻOi aku ka maikaʻi o ka hoʻonui ʻana ma luna o nā ʻōnaehana UV stabilizer maʻamau ... -
