Plastics Additives Handbook, ed. H. Zweifel, 5th edition, 2001, Hanser Publishers
TP VOC:
樹脂のペレットを15O℃に加熱し、揮発性有機化合物をTenaxトラップで−40℃で吸着した。トラップのフラッシュ脱着を230℃で行い。化合物の検出はガスクロマトグラフィ−炎イオン化検出器(GC−FID)を使用して行った。
5gの樹脂ペレットを1リットルの水中に55℃で8日間放置する。得られた水を基準水を用いて0、33、50および66重量%に希釈し、訓練された専門家のパネラーによって味覚テストを実施した。基準水と比較して味の相違が知覚された場合、下記のテーブルに従ってグレードが付与された。
単一キャビティー金型を備えてたNetstal Synergy 1000の射出成形機で樹脂を射出成形した。キャップはPCO1810ネックにフィットする炭酸清涼飲料に適したデザインを有する。ビモダルHPDE樹脂にマスターバッチは加えなかった。
射出成形法B:
96個のキャビティーを有するNetstai Synergy 4200Kの射出成形機で樹脂を射出成形した。キャップはPCO1810ネックにフィットする炭酸清涼飲料に適したデザインを有する。ビモダルHDPE樹脂には赤色顔料を含むマスターバッチを0.8重量%加えた。
訓練されたパネラーに依頼して各キャップを有するボトルの開封の容易さを1〜5の段階で格付けしてもらった。グレード5が開封が最も容易な場合である。
本発明のER−1およびER−3をC−1と比較すると、射出圧力が減り、金型の磨耗が減ることが分かる。すなわち、金型の寿命が延び、および/または、保守頻度が少なくなる。ER−2もC−2と比較して射出圧力が低下している。
