1.Organic polymer auxiliary antioxidant.
2. Faʻaitiitia le faʻafefe o le tafe (MFR) i le lanu i le taimi o le gaosiga o le vevela.
3. E i ai se aafiaga synergistic lelei ma le poloka phenolic antioxidant 1010,1076,313,114, ma isi, ma e mafai foi ona maua ai le tuufaatasiga o oloa e fa i luga.
4.E mafai ona faʻaaogaina faʻatasi ma benzotriazole UV absorbers ma faʻalavelave amine photostabilizers i oloa fafo.
E faʻaaogaina lautele i le polyolefin (e pei o le polyethylene, polypropylene) ma le olefin copolymer, polyamide, polycarbonate, PS resin, PVC, palasitika inisinia, paʻu ma suauu oloa, ABS resin ma isi mea polymer. E mafai foʻi ona faʻaaogaina mea faʻapipiʻi i mea faʻapipiʻi, resini faʻapipiʻi masani poʻo synthetic, ma isi.
Faʻaopoopo le aofaʻi: 0.1% ~ 1.0%, o le aofaʻi faʻaopoopo faʻapitoa e fuafuaina e tusa ai ma le suʻega talosaga a le tagata faʻatau.
Tu'u i totonu 20 Kilokalama / 25 Kilokalama pusa pepa / alumini pepa pepa.
Po'o fa'apipi'i e tusa ai ma mana'oga o tagata fa'atau.
Teu lelei i totonu o se nofoaga mago i lalo ole 25 C ma e lua tausaga e teu ai.
Fa'amolemole fa'afeso'ota'i matou mo so'o se pepa fa'atatau.
