Vamac乙烯丙烯酸弹性体于1975年推出，多年来已成功地应用于要求苛刻的汽车应用领域，在这些领域需要优异的耐热性、发动机和变速器油液或易损性。杜邦最新的制造技术允许生产增强型AEM等级，与现有的标准Vamac弹性体相比，该等级得到了显著改进。这些级别被指定并作为vamac-ultra销售，为目标应用程序的可处理性、性能和客户价值提供了真正的步骤变更改进。新的制造技术现在也应用于一种新的EMA二聚物，即VMX-2122。 Vamac® ethylene acrylic elastomer, introduced in 1975, has been successfully used for many years in demanding automotive applications, where excellent resistance to heat, engine and transmission fluids or Blow-By is required. DuPont's latest manufacturing technology allows production of enhanced AEM grades that are significantly improved compared to the existing standard Vamac® elastomers. These grades, designated and sold as Vamac® Ultra, provide a true step-change improvement in processability, performance and customer value for targeted applications. The new manufacturing technology has now also been applied to a new EMA Dipolymer, called VMX-2122. |
最新的制造技术使AEM级聚合具有优化的结构和化学成分，这比现有标准杜邦VAMAC弹性体提供了显著的改进。这些级别被指定并作为vamac-ultra销售，为目标应用程序的可处理性、性能和客户价值提供真正的步骤变更改进。Vamac® Ultra IP（开发名称：VMX-3040）是第一个商业化的超家族产品。在开发阶段，一个目标是确定在注塑过程中性能比Vamac G有所改善的产品，以减少模具清洗的频率。与标准AEM等级相比，Vamac® Ultra IP 27的高粘度能更好地混合化合物，并提高化合物的绿色强度，有助于避免挤压过程中的塌陷。优化的聚合物结构确保了物理性能的提高，从而改善了密封件、阻尼器和挤压软管等橡胶部件的性能。低磨损值允许在动态密封中长期使用Vamac® Ultra IP。Vamac® Ultra IP的最佳物理性能是在硬度范围为50至90邵尔A的橡胶零件中获得的。使用Vamac® Ultra IP比使用适当的配合物的标准AEM更容易实现该硬度范围的扩展。Vamac® Ultra IP结合了1000小时（六周）内175°C的耐干热性和对汽车润滑油的良好耐受性。最高温度200°C的暴露时间可达4天。同时-31°C的热失重提供了很好的低温灵活性。良好的压缩永久变形和压缩应力松弛特性使Vamac® Ultra IP成为密封应用的最佳选择。在汽车曲轴箱通风系统和风道中具有良好的抗窜气性（热空气、酸、油和汽油烟雾），加上增加的动态阻力是Vamac® Ultra IP的附加属性。像其他等级的VAMAC一样，Vamac® Ultra IP是无卤的。 The latest manufacturing technology allows polymerization of AEM grades with optimized structure and chemical composition, which provides significant improvements over the existing standard DuPont ™ Vamac® elastomers. These grades, designated and sold as Vamac® Ultra, provide true step-change improvement in processability, performance and customer value for targeted applications. Vamac® Ultra IP (developmental name VMX-3040) is the first of the Ultra family products to be commercialized. During the development phase, a goal was to identify a product having improved performance in injection molding processes compared to Vamac® G to reduce the frequency of mold cleaning. The high viscosity of Vamac® Ultra IP compared to standard AEM grades results in better mixing as well as increased green strength of compounds, and helps to avoid collapse during extrusion processes. The optimized polymer structure ensures gains in physical properties resulting in improved performance of rubber parts such as seals, dampers and extruded hoses. Low abrasion values may allow extended use of Vamac® Ultra IP in dynamic seals. The best physical properties of Vamac® Ultra IP are obtained in rubber parts having a hardness range between 50 and 90 Shore A. Extensions of this hardness range may be more easily achieved with Vamac® Ultra IP than standard AEM using appropriate compounding. Vamac® Ultra IP combines dry heat resistance of 175 °C over a period of 1000 h (six weeks) with very good resistance to automotive lubricants. Exposure of peak temperatures of 200 °C are possible for up to four days. At the same time, the Tg of -31 °C provides very good low temperature flexibility. Good compression set and compressive stress relaxation properties make Vamac® Ultra IP an excellent choice for sealing applications. Good resistance to Blow-By (hot air, acids, oil and petrol fumes), present in automotive crankcase venting systems and air ducts combined with increased dynamic resistance are additional attributes of Vamac® Ultra IP. Like every other grade of Vamac® , Vamac® Ultra IP is halogen-free. |
