G21 NA 高粘度 高透明 阻隔性能 無定形共聚酰胺 Grivory 阻隔 

Grivory G 21 Natural是一種部分芳香族、高粘度、無定形共聚酰胺牌號，帶有加工助劑。具有高透明度和高表面光澤度，對風(fēng)味、紫外線輻射具有良好的阻隔性能，并在較高的相對濕度下改善氣體和香氣阻隔。具有良好的耐化學(xué)性和耐磨性。適用于拉伸吹塑、注塑吹塑和擠出鑄造吹膜和吹塑成型的加工。還用作聚酰胺6和不同共聚酰胺的添加劑，以改善薄膜性能。用于紙張涂布、化妝品/個(gè)人護(hù)理包裝、非取向薄膜和取向薄膜、共擠吹塑薄膜、單擠或共擠流延薄膜、單層和多層管、容器和單擠或共擠硬包裝（EBM 或 ISBM 瓶）的阻隔層的制造等應(yīng)用。符合歐盟 FDA、USP VI（醫(yī)療）、REACH、RoHS 和 WEEE。

Grivory G 21 Natural is a partially aromatic, high viscosity, amorphous copolyamide grade with processing aid. Possesses high transparency and high surface gloss, good barrier properties towards flavor, UV-radiation and improved gas and aroma barrier at elevated relative humidity. Provides good chemical- and abrasion resistance. Is suitable for processing by stretch blow molding, injection blow molding and extrusion cast- and blown film and blow molding. Is also used as an additive for polyamide 6 and different co-polyamides to improve film properties. Used in applications like paper coating, cosmetics /personal care packaging, non-oriented film and oriented film, manufacturing of coextruded blown film, mono- or coextruded cast film, mono- and multilayer tubes, containers and barrier layer for mono- or co-extruded rigid packaging (EBM or ISBM bottles). Complies with EU FDA, USP VI (for medical), REACH, RoHS and WEEE.
