有機錫T-12

NT CAT 12可用來替代傳統的二月桂酸二丁基錫和辛酸亞錫等催化劑用于聚氨酯泡沫、涂料、膠粘劑和彈性體等,應用范圍相當廣泛。

有機錫穩定劑

NT CAT 12 是一種新型有機錫催化劑,催化活性很高,且不含二丁基錫、二辛基錫等8中被歐盟限制的有毒的有機錫化合物,符合歐盟污染檢驗標準;

二月桂酸二丁錫

別名:二丁基錫二月桂酸酯,聚氨酯催化劑T-12,有機錫催化劑T12,有機錫-T12,催化劑T-12,有機錫T-12,二月桂酸二丁錫,有機錫穩定劑

辛酸亞錫

異辛酸亞錫是白色或淡黃棕色膏狀物,有時稱作辛酸亞錫。溶于石油醚,不溶于水。是生產聚氨酯泡沫塑料的基本催化劑,主要用于聚醚-聚氨酯發泡時的膠化反應,也可以作為氨酯泡沫塑料防老劑。用作聚氨酯合成和室溫硫化硅橡膠的催化劑。也用作環氧樹脂催化劑型固化劑。

有機錫催化劑

聚氨酯保溫材料的主要原料之一是聚氨酯硬泡組合聚醚。聚氨酯硬泡組合聚醚又稱白料,與聚合MDI共稱黑白料。適用于建筑保溫、保冷、太陽能、熱水器、冷庫、恒溫庫、啤酒罐、冷藏等需要保溫保冷的各種場合。

聚氨酯組合料特點:

1、獨特的隔熱保溫性能,節電效率高、環保;
2、重量輕,降低載荷;具優良的防水性能,保溫、防水合二為一;
3、設計簡單、效率高、進度快、質量好、壽命長;
4、無氟發泡,適應環境寬;
由于大型罐體保溫層成型(特指澆注型)時無法設計閉模方式,在成型過程中無法產生必要的閉模擠壓效果,因而處于半自由發泡狀態成型的泡沫常會有不可避免的成型收縮性,如該收縮性較大或者不均勻會造成保溫效果下降、外觀不雅等現象,如何嚴控該收縮性是罐體配料、選材的至關重要的一環。
