ʻO ke ʻano

ʻO DB 886 kahi 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.

Nā noi

Hāʻawi ʻo DB 886 i ka paʻa UV koʻikoʻi i nā ʻōnaehana polyurethane.

ʻO ka hoʻonui maikaʻi ʻana ma luna o nā ʻōnaehana UV stabilizer maʻamau i ʻōlelo nui ʻia i nā noi TPU māmā a māmā paha.

Hiki ke hoʻohana ʻia ka DB 886 i nā polymers ʻē aʻe e like me nā polyamides a me nā plastic engineering ʻē aʻe e pili ana i ka polyketone aliphatic, styrene homo- a me nā copolymers, elastomers, TPE, TPV a me nā epoxies a me nā polyolefins a me nā substrates organik ʻē aʻe.

Hāʻawi ʻo DB 886 i ka hana ʻoi aku ka maikaʻi a me ka hoʻonui ʻana i ka huahana

ma luna o nā ʻōnaehana hoʻopaʻa māmā maʻamau:

Ke kala mua maikaʻi loa

ʻOi aku ka paʻa ʻana o ka waihoʻoluʻu i ka wā e ʻike ai i ka UV

Hoʻonui i ka lōʻihi-thermal-paʻa

Hoʻonā hoʻohui hoʻokahi

Maʻalahi dosageble

Nā ʻano huahana keʻokeʻo a i melemele liʻiliʻi, ka pauka kahe manuahi

Nā kuhikuhi no ka hoʻohana ʻana

E hoʻohana i nā pae no DB 886 ma waena o 0.1 % a me 2.0 %

ma muli o ka substrate a me nā kūlana hana. Hiki ke hoʻohana wale ʻia ʻo DB 866 a i hui pū ʻia me nā mea hoʻohui hana ʻē aʻe e like me nā antioxidants (hindered phenols, phosphites) a me HALS light stabilizers, kahi e ʻike pinepine ʻia ai kahi hana synergistic. Loaʻa ka ʻikepili hana o DB 886 no nā noi like ʻole
