为汽车工业创造了两种基于汇丰的Evoprene TPE化合物,这两种化合物都经过专门配制,具有非常低的雾化特性,适用于汽车内饰应用。根据SAE J1756,Evoprene LF等级满足反射雾试验的要求,而Evoprene GF等级满足DIN75201B重力雾试验标准。不同的汽车制造商喜欢不同的方法。所有这些Evoprene化合物都基于成熟的氢化苯乙烯嵌段共聚物(HSBC)TPE技术,该技术为汽车设计师和处理器提供了性能和加工特性的完美融合。所有等级的产品都可以在标准热塑性塑料设备上注射成型或挤压成型-我们的Evoprene加工指南中提供了完整的详细信息。化合物可以在不同程度的抗紫外线能力下配制,这取决于车辆中零件的使用位置。虽然它们通常是作为母料或黑色的天然原料供应,但Evoprene LF和GF化合物在较长的化合物运行时间内生产时,其颜色可符合特定的汽车要求。热老化试验表明,这些化合物的热稳定性远远超过汽车和卡车记录的最高和最低温度。 Two ranges of HSBC based Evoprene™ TPE compounds have been created for the Automotive Industry, both specially formulated to have very low fogging characteristics suitable for automotive interior applications. Evoprene™ LF grades meet the requirements of the Reflectance Fogging test according to SAE J1756 whilst the Evoprene™ GF grades satisfy the DIN 75201B Gravimetric Fogging standard. Different automotive makers prefer different methods. All these Evoprene™ compounds are based on the well established hydrogenated styrene block copolymer (HSBC) TPE technology which offers a great blend of performance and processing characteristics to both automotive designers and processors alike. All grades can be injection moulded or extruded on standard thermoplastics equipment - full details are available in our Evoprene™ processing guides. Compounds can be formulated at various levels of UV resistance, depending on where in the vehicle the parts are to be used. Whilst they are normally supplied as natural for masterbatching, or black, Evoprene™ LF and GF compounds can be colour matched to specific automotive requirements when produced in longer compound runs. Heat ageing tests demonstrate these compounds are thermally stable to well beyond the maximum and minimum temperatures recorded in cars and trucks. |
