    以科技为立足之本,在全球范围内活跃于健康、营养和材料领域的荷兰皇家帝斯曼集团开发出新型耐水解PBT,为Arnite®热塑性聚酯系列再添新产品。新材料将为耐高温潮湿环境应用(包括汽车连接器、控制设备和传感器)提供高性价比解决方案。
    Royal DSM, a global science-based company active in health, nutrition and materials, is adding hydrolysis-resistant grades of polybutylene terephthalate (PBT) to its Arnite® family of thermoplastic polyesters. The new materials will provide a cost-effective solution in applications exposed to humidity and high temperatures, including automotive connectors, control devices, and sensors.
    该款新型耐水解产品可满足汽车市场对耐高温高湿材料日益增长的需求,适用于尚不需使用例如帝斯曼Stanyl®PA46和ForTii®PA4T等高性能耐高温聚酰胺材料的应用。
    The new ‘HR’ grades come in response to increasing calls in the automotive market for materials that resist hot and humid environments, for applications that do not necessarily require the outstanding performance of high temperature polyamides like DSM’s Stanyl® PA46 and ForTii® PA4T products.


    帝斯曼汽车电子全球市场经理Mark Terlaak表示:“我们从客户那里获悉,随着连续使用时间和发动机环境峰值温度的持续上升,聚酰胺6、聚酰胺66和标准PBT等材料已不能满足特定应用的要求。各级供应商将耐水解PBT视为从这些材料转换到更昂贵的特种材料解决方案的过渡材料。”
    “Our customers are telling us that with continuous-use and peak temperatures around the engine continuing to rise, materials like polyamides 6 and 66 and standard PBT are no longer good enough for the job in some applications,” says Mark Terlaak, Global Segment Leader,Automotive Electronics. “Many Tiers see HR PBT as a bridge between these materials and more expensive specialty solutions."
       
    Terlaak还指出,PBT的性能优于用于汽车电子应用的标准聚酰胺,因为其无需使用热稳定剂(某些热稳定剂可导致金属接触腐蚀问题),而且因其吸湿性较低也保证了较高的尺寸稳定性。
    Terlaak also points out that PBT scores over standard polyamides for automotive electronic applications because it does not require the use of heat stabilizers (some of which are the source of corrosion problems on metal contacts) and because its lower moisture absorption leads to higher dimensional stability.


    新型Arnite耐水解PBT产品在诸多方面都优于其他PBT,但其最显着的优势是:在USCAR标准3、4、5类型温度/湿度环境和双85湿热循环试验(85℃和85%相对湿度)下,在长达3000小时内其机械性能具备良好的保持率。Terlaak指出,该产品在150℃时具有极佳的性能。他补充道:“我们的产品在流动性和结晶速度方面优于几乎所有同类产品,可以节约生产周期时间,并可在整个生命周期内保持良好的机械性能。”
    The new Arnite HR grades stand out from the pack of PBTs in many ways, but most notably in their higher retention of mechanical properties after USCAR Class 3, 4, and 5 temperature/humidity profile exposure and ‘85/85’ cycles (85°C/85% relative humidity) of up to 3000 hours. Terlaak also notes that performance at 150°C is exceptional. “Our grades will outperform virtually all the competition in terms of flow, speed of crystallization – which translates into production cycle time – and mechanical property retention over the lifetime of the vehicle,” he adds.
    在设定耐水解PBT系列产品的目标性能时,帝斯曼不仅考虑了当今汽车行业的需求,还考虑了该产品未来将如何发展以顺应汽车行业所面临的变革。随着电动车和自动驾驶汽车的趋势日益增强,该新型产品将面临更高的强度测试和验证标准。

    When targeting the performance it wanted to achieve from the Arnite HR family, DSM took into consideration not only the needs of the automobile industry today, but also how they are likely to change in the future. The new grades have been engineered in anticipation of more robust testing and validation standards as the trend towards electric-powered and autonomous road vehicles picks up.
        
    帝斯曼现在推出两种30%玻纤增强的新型Arnite耐水解PBT产品,其中一种提升了有机硅粘性。该系列产品组合完善后,将涵盖包括各种不同牌号玻纤增强型产品,厚度为0.4毫米时UL94防火等级高达V0的阻燃产品,冲击改性产品,以及用以提高有机硅密封胶粘性的产品。
    DSM is launching the new Arnite family with two 30% glass reinforced grades, one with enhanced silicone adhesion. When complete, the range will include grades with various levels of glass fiber reinforcement, flame retardant grades with UL 94 ratings of up to V-0 at thicknesses as low as 0.4 mm, impact-modified grades, and grades engineered to provide high levels of adhesion to silicone sealants.
        
    Terlaak总结说:“该新型Arnite PBT产品系列的推出,巩固了帝斯曼作为全球少数能为汽车电子应用提供全方位产品服务组合的塑料供应商之一的地位。
    “The addition of this new Arnite PBT family strengthens our position as one of the few plastics suppliers in the world with a full-service automotive electronics portfolio,” Terlaak concludes.
