杜邦Vamac® GXF是乙烯、丙烯酸甲酯的三元共聚物,也是使用胺基硫化系统固化的固化部位单体。与VAMAC G相比,Vamac® GXF具有更好的高温性能和动态抗弯曲疲劳性能。Vamac® GXF包括少量加工助剂,其名义比重为1.03。它有轻微的丙烯酸气味。在储存、混合和加工过程中,应充分通风,防止残余蒸汽积聚。储存稳定性极佳。Vamac® GXF非常适合那些需要在VAMAC G上改善高温性能或提高动态弯曲疲劳阻力的应用,并且可以承受稍长的固化时间。从Vamac® GXF的性能改进中受益的典型应用是风管、软管和扭转阻尼器。Vamac® GXF的化合物与vamac g相比具有更长的烧焦时间以改进加工和略高的压缩永久变形。提高了高温下的延伸率和性能,显著提高了动态弯曲疲劳抗力。热老化和流体老化是相似的。Vamac® GXF非常适合于注塑、转移和压缩成型,并且易于挤压。 DuPont™ Vamac® GXF is a terpolymer of ethylene, methylacrylate, and a cure site monomer cured using an amine-based vulcanization system. Compared with Vamac® G, Vamac® GXF has improved high temperature properties and better dynamic flex fatigue resistance. Vamac® GXF includes a small amount of processing aid, and has a nominal specific gravity of 1.03. It has a mild acrylic odor. Use adequate ventilation during storage, mixing, and processing to prevent accumulation of residual vapors. Storage stability is excellent. Vamac® GXF is well suited for those applications which need improved high temperature properties or improved dynamic flex fatigue resistance over Vamac® G and can tolerate a slightly longer cure time. Typical applications that would benefit from the improved properties of Vamac® GXF are air ducts, hoses and torsional dampers. Compounds of Vamac® GXF compared to Vamac® G have longer scorch time for improved processing and slightly higher compression sets. Elongation and properties at elevated temperature are improved resulting in significantly improved dynamic flex fatigue resistance. Heat and fluid aging is similar. Vamac® GXF is well suited for injection, transfer and compression molding, and is easily extruded. |
