胺催化劑A33是含有33%三乙烯二胺(TEDA)的液體催化劑,這種高活性叔胺催化劑促進(jìn)異氰酸酯與多元醇反應(yīng),使泡沫交聯(lián)。并給予軟性聚氨酯泡沫塑料良好的機(jī)械性能。如配合使用胺催化劑A1,便能獲得這胺催化劑A33的最佳效能。 物理性質(zhì): 形狀:無(wú)色或淡黃色液體 純度≥99%; 水分≤0.5%; 黏度(25℃):100mPa.s; 密度(20℃):1.033g/cm3; 閃點(diǎn)(PMCC):79℃; 蒸汽壓(38℃):266Pa 胺催化劑A33產(chǎn)品應(yīng)用: 柔美A33的有效成分是三乙烯二胺,由33%的三乙烯二胺與67%的一縮二丙二醇所配制成的溶液。 柔美A33主要用作聚氨酯泡沫塑料的凝膠催化劑,廣泛用于軟質(zhì)、半硬質(zhì)、硬質(zhì)聚氨酯泡沫塑料、涂料、彈性體,在聚氨酯發(fā)泡體系中,異氰酸酯首先和三乙烯二胺反應(yīng)生成活性絡(luò)合物,絡(luò)合物的性質(zhì)很不穩(wěn)定,一旦氨基甲酸酯鍵生成后,它就會(huì)游離出來(lái),有利于更進(jìn)一步催化,三乙烯二胺對(duì)凝膠反應(yīng)和發(fā)泡反應(yīng)都有較強(qiáng)的催化作用,尤其對(duì)聚氨酯和羥基的催化作用選擇性更強(qiáng)。 胺催化劑A33適用于所有種類(lèi)的聚氨酯泡沫制造。它能完全溶于水并能與多元醇、氟碳化合物及亞錫催化劑完全混合。在所有泡沫配方中,三倍胺催化劑A33可取代一倍的固體三乙烯二胺,例如0.3php胺催化劑A33可替代0.1php固體三乙烯二胺。 胺催化劑A33在聚氨酯軟泡、聚氨酯硬泡、海綿大泡、高回彈海綿、汽車(chē)座椅高回彈、噴涂硬泡、仿木硬泡、聚氨酯組合料、防水涂料、聚氨酯膠黏劑中都有廣泛的應(yīng)用。 Amine catalyst A33 Amine catalyst A33 is a liquid catalyst containing 33% triethylenediamine (TEDA). This highly active tertiary amine catalyst promotes the reaction of isocyanates with polyols, resulting in foam cross-linking. The flexible polyurethane foam has good mechanical properties. The optimum performance of the amine catalyst A33 can be obtained if the amine catalyst A1 is used in conjunction with the amine catalyst A1. Physical properties: Shape: colorless or pale yellow liquid A purity of 99% or more. Moisture 0.5% or less; Viscosity (25℃) : 100mPa. S; Density (20℃) : 1.033g/cm3; Flash point (PMCC) : 79℃; Vapor pressure (38℃) : 266Pa Application of amine catalyst A33: Amine catalyst A33 is suitable for all types of polyurethane foams. It is completely soluble in water and can be thoroughly mixed with polyols, fluorocarbons and stannous catalysts. In all foam formulations, triethylamine catalyst A33 replaces one time solid triethylenediamine, for example, 0.3 php-amine Catalyst A33 replaces 0.1 PHP solid triethylenediamine. Amine catalyst A33 is widely used in polyurethane soft foam, polyurethane hard foam, sponge foam, high rebound sponge, car seat high rebound foam, spraying hard foam, imitation wood hard foam, polyurethane composite material, waterproof coating and polyurethane adhesive. 供應(yīng)商 東莞市柔美新材料科技有限公司 柔美®更多產(chǎn)品 ZF-10:高效低氣味發(fā)泡催化劑,典型應(yīng)用于制備低氣味聚氨酯泡沫制品 ZR-50:低氣味凝膠催化劑,提供優(yōu)良的平衡性,可用于聚氨酯模塑高回彈泡沫 Z-131:反應(yīng)型低氣味凝膠胺類(lèi)催化劑復(fù)配劑 Z-130:低氣味凝膠催化劑,平衡凝膠/發(fā)泡 ZR-70:低氣味催化劑,用于包裝泡沫和在乙烯基表皮上模塑泡沫發(fā)泡和凝膠平衡性好 ZR-40(五甲基二亞丙基二胺):對(duì)冷模塑高回彈泡沫特別有效,低氣味凝膠和發(fā)泡平衡較好的催化劑 LE-310:應(yīng)用于大塊海綿的低氣味反應(yīng)型凝膠催化劑,新型的低VOC胺凝膠催化劑,胺含量超過(guò)95% LE-530:反應(yīng)型凝膠催化劑,用于各種聚氨酯發(fā)泡產(chǎn)品 DPA:低氣味凝膠催化劑,突出的平衡性和通用性提供良好的流動(dòng)性 TAP 1-甲基-4-(2-二甲氨基乙基)哌嗪:卓越的三聚催化劑,可提高流動(dòng)性 DMDEE(2,2'-二嗎啉二乙基醚):強(qiáng)發(fā)泡催化劑,提供穩(wěn)定的預(yù)聚物體系 DMAEE:低密度全水硬質(zhì)泡沫以及低密度半硬質(zhì)泡沫 BDMAEE 雙-(2-二甲氨基乙基)醚:高效發(fā)泡催化劑 BDMA(N,N-二甲基芐胺):聚氨酯硬泡催化劑、環(huán)氧促進(jìn)劑 DMEA(N,N'-二甲基乙醇胺):在一些硬泡體系中中和酸, PMDETA(五甲基二亞乙基三胺):對(duì)HCFC/水發(fā)泡的硬泡特別有效,類(lèi)似PC5
