与Vamac G相比，杜邦Vamac® Ultra LT聚合物改善了低温性能。Vamac® Ultra LT 27聚合物的Tg比Vamac G的Tg低约12°C。由Vamac® Ultra LT制成的化合物与20 phr增塑剂的Tg为-54°C。不含增塑剂的化合物的Tg为-40°C，该化合物在空气中老化后保持Tg为-40°C。在150°C下6周或在175°C下1周。Vamac® Ultra LT种化合物的耐流体性不如g/gls化合物，但可以通过与vamac g混合来提高耐流体性。与g混合的混合物将具有中低温性能和中间耐流体性。聚合物通常用二胺固化。它也可以用过氧化物固化。橡胶弹性体具有低水平的加工助剂和1.03的名义比重。该聚合物具有温和的丙烯酸气味，且贮存稳定性好。由Vamac® Ultra LT制成的固化化合物具有良好的性能组合，包括适用于最终使用温度的宽操作窗口。不含增塑剂的化合物具有-40°C至165°C的温度窗口，并且该化合物能够承受高达200°C的短期温度峰值。通过添加增塑剂可以改善低温性能，并且对于20 phr增塑剂，初始Tg约为-54°C。固化化合物通常被评定为E级。对于使用ASTM D2000系统的耐热性，这意味着它们将在175°C（347°F）下通过70小时的额定热试验。它们还将在高达165°C（329°F）的温度下通过为期六周的空气老化要求。固化化合物的耐流体性取决于炭黑和增塑剂的含量。在150°C（302°F）下老化168小时后，IRM 903流体的体积膨胀的典型值约为90%。由Vamac® Ultra LT制成的化合物在变速器油和发动机机油中的体积膨胀要小得多。工作流体105（1周/150°C）中的体积膨胀约为50%，而ASTM 1（1周/150°C）中的体积膨胀约为7%。大多数新的发动机机油、变速器油和高温润滑脂比传统的测试油更合成，脂肪含量更高。新的液体也有更低或没有芳香含量。IRM903中的体积膨胀可能不是新流体性能的一个很好的预测因子。基于Vamac® Ultra LT的化合物的压缩设定值在150°C下一周后测量，其范围为20到40%。结果取决于疗效包装、炭黑含量和增塑剂含量。在Vamac® Ultra LT 27化合物上进行的CSR（压缩应力松弛）试验在150°C的机油中显示出非常好的性能，持续6周。保留密封力的百分比是一个相对较高的值，这可能是由于相对较高的体积膨胀。Vamac® Ultra LT化合物与vamac g化合物相比具有更高的值，与vamac gls化合物相比，vamac g化合物具有更高的保留密封力。Vamac® Ultra LT化合物的特性使其非常适合各种汽车应用，包括成型护套、动力总成密封件和垫圈、摇臂盖密封件、变速器油冷却液软管、动力转向软管、涡轮增压器软管、曲轴箱通风管、燃油和冷却液软管的覆盖物、O形圈、套圈和曲柄轴。后减振器。Vamac® Ultra LT是一种无卤聚合物，当暴露在火焰中时不会分解以释放腐蚀性气体。可用于阻燃、低烟、无卤电线电缆护套及无卤、低烟地板。Vamac® Ultra LT化合物非常适合于注射、转移或压缩成型。它们也可以被挤压。 DuPont™ Vamac® Ultra LT polymer has improved low-temperature properties compared to Vamac® G. 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.

智能注塑，伊之密加速释放变革力量

搜料网资讯：

随着数字化转型的大幕徐徐开启，塑料机械也加速布局智能注塑。在Chinaplas2021开幕当天，伊之密展示的智能注塑设备FF系列电动注塑机和YiMES智造执行系统吸引了许多客商的关注，伊之密也成为最值得打卡的展台之一。

硬核技术方案亮相

今年雅式展，致力技术创新的伊之密让人眼前一亮，从外观功能、降本增效、智能化等方面升级客户价值，提供整体解决方案。

在塑料产品外观功能升级方面，伊之密展示了ReactPro聚氨酯与注塑一体化成型方案2.0 版本，可实现同时兼具软触感、自修复、耐腐蚀、耐刮擦的产品性能及高光、哑光纹路的视觉效果，方案还采取PU国产材料，让综合成本大幅下降。

包装产品也带来新的客户体验，PAC250K高速包装注塑机搭载FoamPro微发泡工艺，实现对包装产品更多设计自由、减少翘曲变形、外观灵活多样、节能降本和质感更优的深度开发。

在满足塑料产品外观及结构多样化的多色多物料应用上，伊之密带来了Multipro三色电动牙刷手柄一步成型解决方案，NSW驮式多物料注塑机一步生产集PC本体、TPU按键软胶、PMMA指示灯透明外壳于一身的三色电动牙刷柄，实现高集成度高效生产。

智能化纳入产品开发重点

除了工艺应用升级，伊之密在智能化领域也不断革新。一方面是智能设备，本次雅式展，伊之密FF系列电动注塑机亮出了多个自主研发的智慧功能，如SCFM智能锁模力管理系统、SIC智能射出控制技术，展示了64+64 免喷涂USB数据线上下壳叠模方案和蓝牙耳机仓整体解决方案。

将智能化纳入产品开发，是伊之密产品升级迭代的重点。伊之密董事副总经理兼注塑机事业部总经理张涛表示：“注塑机下一步的发展一定是要满足整个行业和客户的预期跟发展趋势，所以越来越多的智能元素会成为伊之密主机技术里的组成部分。”他介绍，伊之密已规划和建立了智能注塑成型系统的技术体系，可以满足高要求客户对机器智能化和注塑成型系统智能化的新要求。

展会上另一个革新的则是智能制造，YiMES智造执行系统的新功能首次亮相——智能集成工艺管控，高端智能设备和周边辅机工艺数据可一键上传、下发，无需人工输入调整；节能烘干系统，实时监测材料加热过程，并将数据与YiMES系统集成，自动计算加工的电能成本，进行节能数据分析，达到降本节能的效果。

“数字化和信息化能够帮助塑料加工企业把他们目前的一些现状进行提升和改善，将帮助我们不同行业的客户实现数字化转型，提升行业管理水平。”张涛告诉记者，伊之密建立平台型的YiMES系统，能帮助客户做好工艺技术管理、质量监控、订单管理、能耗管理等工作，相信随着信息化的平台越来越多地导入下游客户，会助推整个行业进一步的发展。
