The Tg for Vamac® Ultra LT polymer is about 12°C lower than the Tg for Vamac® G. A compound made from Vamac® Ultra LT with 20 phr of plasticizer has a Tg of -54°C. A compound without any plasticizer has a Tg of -40°C and that compound maintains that Tg after aging in air for six weeks at 150°C or for one week at 175°C. The fluid resistance of Vamac® Ultra LT compounds is not as good as the G/GLS compounds, but resistance can be improved by blending with Vamac® G. The blends with G will have intermediate low-temperature performance and intermediate fluid resistance. The polymer is typically cured with a diamine. It can also be cured with a peroxide. The gum elastomer has a low level of a processing aid and a nominal specific gravity of 1.03. The polymer has a mild acrylic odor and the storage stability of the polymer is excellent. Cured compounds made from Vamac® Ultra LT have a good combination of properties including a wide operating window for end use temperatures. A compound with no plasticizer has a temperature window of -40°C up to 165°C and the compound can withstand short term temperature spikes up to 200°C. The low temperature properties can be improved by the addition of a plasticizer, and with 20 phr of plasticizer the initial Tg is about -54°C. The cured compounds are typically rated as class E for heat resistance using the ASTM D2000 system and this means that they will pass a heat rating test of 70 hours at 175°C (347°F). They will also pass a six week air aging requirement at temperatures as high as 165°C (329°F). The fluid resistance of a cured compound depends on the carbon black and plasticizer level. A typical value for volume swell in IRM 903 fluid after aging for 168 hr at 150°C (302°F) is about 90%. The compounds made from Vamac® Ultra LT have much lower volume swell in transmission fluid and in engine oils. The volume swell in Service Fluid 105 (1 week/150°C) is about 50% and the volume swell in ASTM #1 (1 week/150°C) is about 7%. Most of the newer engine oils, transmission fluids, and high temperature greases are more synthetic and have higher aliphatic content than conventional test oils. The newer fluids also have much lower or no aromatic content. The volume swell in IRM903 may not be a good predictor for performance in the newer fluids. The compression set values for compounds based on Vamac® Ultra LT were measured after one week at 150°C and the range in values is from 20 to 40%. The results depend on the curative package, the level of carbon black and the level of plasticizer. CSR (Compressive Stress Relaxation) tests run on Vamac® Ultra LT compounds exhibit very good properties for six weeks at 150°C in engine oils. The percent retained sealing force is a relatively high value and this is probably due to the relatively high volume swell. The Vamac® Ultra LT compounds have higher values compared to the Vamac® G compounds which in turn have higher retained sealing forces compared to Vamac® GLS compounds. The properties of Vamac® Ultra LT compounds make them well suited for a wide range of automotive applications, including, molded boots, powertrain seals and gaskets, rocker cover seals, transmission oil coolant hoses, power steering hoses, turbocharger hoses, crankcase ventilating tubes, coverings for fuel and coolant hoses, O-rings, grommets and crankshaft dampers. Vamac® Ultra LT is a halogen free polymer and does not decompose to give off corrosive gases when exposed to flame. It can be used for flame retardant, low-smoke, non-halogen wire and cable jackets and in non-halogen, low smoke flooring. Vamac® Ultra LT compounds are well suited for injection, transfer or compression molding. They also can be extruded. 总体材料状态 • 已商用：当前有效资料 1 • Technical Datasheet (English) 供货地区 • 北美洲 • 欧洲添加剂 • 加工助剂性能特点 • 耐低温 • 耐热性，高 • 无卤用途 • 垫圈 • 管道 • 密封 • 垫圈 • 管道 • 汽车领域的应用：外观 • 不透明 • 清晰/透明形式 • 包加工方法 • 挤出 • 压缩模塑 • 树脂传递成型 • 注射成型 Vamac® Ultra LT 乙烯丙烯酸弹性体 DuPont Performance Elastomers 物理性能额定值单位制测试方法门尼粘度 ASTM D1646 121°C 3 8MU 121°C 12MU ML 1+4, 100°C 4 11MU ML 1+4, 100°C 3 23MU ML 1+4, 100°C 37MU 弹性体额定值单位制测试方法拉伸应力 3 (100%应变) 3.10MPa ASTM D412 抗张强度 ASTM D412 屈服 3 11.0MPa 屈服 14.3MPa 伸长率 3 (断裂) 360% ASTM D412 撕裂强度 5 ASTM D624 -- 3 27.7kN/m -- 28.2kN/m 压缩永久变形 ASTM D395 150°C, 70.0 hr 3 25% 150°C, 70.0 hr 22% 150°C, 138 hr 31% 150°C, 168 hr 3 35% 硬度额定值单位制测试方法硬度计硬度 ASTM D2240 邵氏 A 3 63 邵氏 A 60 热性能额定值单位制测试方法玻璃转化温度 ASTM D3418 -- 3 -54.0°C -- -42.0°C 玻璃化转变温度 ASTM D3418 DMA Results - dan delta 6 -41°C DMA Results - dan delta 7 -32°C DMA Results - loss modulus 6 -45°C DMA Results - loss modulus 7 -37°C Static O-Ring test 6 -63°C Static O-Ring test 7 -55°C TR10 -39°C TR10 3 -45°C TR30 3 -33°C TR30 -32°C 老化额定值单位制测试方法 Change in Glass Transition Temperature -- 8 -46°C ASTM D471 -- 9 -52°C ASTM D471 -- 10 -44°C ASTM D471 -- 11 -51°C ASTM D471 150°C 12 -47°C ASTM D573 150°C 13 -42°C ASTM D573 175°C 14 -43°C ASTM D573 175°C 15 -41°C ASTM D573 Vamac® Ultra LT 乙烯丙烯酸弹性体 DuPont Performance Elastomers 补充信息额定值单位制测试方法 MDR ASTM D5289 MH : 177°C 16 9.63dNm MH : 177°C 17 7.83dNm ML : 177°C 16 0.410dNm ML : 177°C 17 0.370dNm t50 : 177°C 16 2.1min t50 : 177°C 17 2.1min t90 : 177°C 16 9.4min t90 : 177°C 17 8.9min ts2 : 177°C 17 1.4min ts2 : 177°C 16 1.2min Mooney Scorch ASTM D1646 t10 : 121°C 14.8min t10 : 121°C 3 17.4min t3 3 10.1min t3 : 121°C 9.2min 挥发性 0.6wt% 内部方法东莞市双帮塑胶原料有限公司大量销售塑料AEM Ultra LT AEM/美国杜邦/ 因为塑料价格行情每天都有新的变化前天的报价不等于今天的报价。如果需要新的价格请电：13549213581，肖生。
