VESTAMID®生 产 竖 琴 弦 的 成 功 是 Evonik和 NTEC之 间 出 色 合 作 的 成 果。Evonik提供原料和生产技术，同时 NTEC贡献了其加工乐器弦方面特殊单 丝的多年经验。” S ince the late 1930s, growing numbers of instruments have used strings made of robust nylon fibers. There are obvious benefits to these – they are envi- ronmentally stable, durable, and easy to use. The monofilament made from VESTA- MID ® D18 that Evonik and NTEC have developed, a polyamide 612 (PA 612), meets all these requirements and also ex- cels thanks to its outstanding transpa- rency and smooth surface. This last pro- perty gives musicians better dexterity when playing, while the high level of transparency enhances the clarity and tone of the strings. On the process side, the new filament VESTAMID ® 创新的应用始于1930 年代晚期，使用强劲的尼龙纤维作弦的 乐器数量在增长。采用这种弦绝对是有 好处的：尼龙弦在各种环境下都很稳 定，耐用且使用方便。 Evonik 和NTEC共同开发的单丝采 用 VESTAMID ® D18，尼龙 612（ PA 612），由于其具有极好的透明度和平 滑的表面，能满足甚至超过所有需求。 这一最新的特性为音乐家在演奏时提供 了更好的灵敏度 ，同时透明性提升了弦 的清晰度和音色。 在工艺方面，新的单丝过人之处在 于出色的加工稳定性，这样就保证了同 样的长度的弦其直径、回弹性以及可伸 缩性的稳定。 Evonik高性能聚合物业务领域经理 Derek Shi说：“我们致力于通过范围广 泛的特色聚合物原料向用户提供促进创 新的方案。基于 PA612尼龙制成的弦旨 在让专业的乐器有着令人愉悦的清晰的 声音。” VESTAMID®用于竖琴弦 采用VESTAMID® D18制成的弦， 特色为具有平衡的机械特性和低的吸水 性。这使得琴弦在潮湿或湿润的环境下 仍然能保持稳定的频率和音高。 已开发的竖琴弦 单丝的直径范围 0.5-0.7mm 。但不同的直径和收卷方式 的弦可以同样用在其它弦乐和弹拨乐 器，例如小提琴。 成功的合作 Evonik粒子和混合料产品线负责人 Iordanis Savvopoulos博士指出： “采用 Evonik 的VESTAMID ® Raw 原料：和弦之声 Raw Materials: Evonik’s VESTAMID ® sounds the chord scores points with its excellent process- ing stability, which guarantees the same length of string diameter, resilience and scalability. Derek Shi, a manager from Evonik’s High Performance Polymers Business Line, says: “We are committed to bringing the innovative solutions to the users by means of our wide range of specialty po- lymers. The concept of PA 612-based ny- lon strings is aimed at professional musi- cal instruments with a pleasant and clear sound.” VESTAMID ® for harp strings Strings made of VESTAMID ® D18 feature balanced mechanical properties and low hygroscopicity. This allows them to main- tain stable frequency and pitch in moist or humid environments. The monofilament with a diameter range of 0.5-0.7mm was originally deve- loped for harp strings but with different diameters and winding methods can Evonik和NTEC采用Evonik的VESTAMID® D18尼龙 612联合开发出了用于乐器弦的新 型单丝 Evonik and NTEC have jointly developed a new monofilament for instrument strings using VESTAMID ® D18 – polyamide 612 – from Evonik (Source: Saladorec) 32 原料 Extrusion Asia Edition 2/2017 Evonik和中国富有经验的单丝生产 商NTEC合作，共同开发成功了新 型单丝，采用Evonik的高性能塑料 VESTAMID ® ，生产乐器的弦。 Evonik and NTEC, an experienced manufacturer of filaments based in China, have jointly developed a new monofilament using Evonik’s high performance plastic VESTAMID ® for instrument strings .
