Delrin ® 300TE的熔体流动指数(MFI190/2,16) 为 6 g/10min，弥补了兼具高粘度和极高抗冲击性的Delrin ® 100T(MFI = 2) 与中等粘度、更硬Delrin ® 500T(MFI = 12)。
杜邦™ Delrin ® 300TE比 Delrin ® 300PE具有更高的抗冲击性，后者是先前推出的低排放等级，也适用于汽车内饰。它在23 ° C下实现了18kJ/m ²的缺口冲击强度（Delrin ® 300PE：11kJ/m ²）。在-30 ° C，新300TE级的缺口冲击强度仍高达10千焦耳/米²（300PE：8千焦/米²）。
与杜邦的缩醛树脂系列的所有成员一样，新型Delrin ® 300TE还结合了在广泛温度范围内的高强度、硬度和刚度、高耐磨性和低摩擦系数、高热变形温度、良好的电气和介电性性能和高尺寸稳定性。
Kirner补充道：“由于其高熔体流动性，具有长流动路径的薄壁部件——例如用于头枕的支柱——是Delrin ® 300TE开发的主要领域之一。所有POM 等级都适合使用在低噪音和低摩擦的控制和驱动系统中。” 用于精密小零件的其他低排放等级正在开发中。

Delrin ®缩醛树脂在车辆中的应用范围，将塑料部件包括在需要高抗冲击载荷的内饰中。
这范围从广泛的可见部件到小型的功能部件，如杠杆和齿轮，现在还包括汽车内饰中的应用，例如在座椅区域，需要抵抗高冲击载荷。

杜邦汽车内饰材料开发 Kirner表示：“鉴于消费者对质量的要求不断提高，汽车行业对挥发性有机化合物 (VOC)的排放设定了极低的限制。“由位于德国赫腾的独立费森尤斯研究所进行的新型抗冲改性 Delrin ® 300TE样品测试显示，甲醛排放量为1.0 mg/m ²及更低。这样的结果远低于 2.0 mg/m 的限值²由的德国原始设备制造商设定，意味着新材料符合世界上该行业对VOC 排放严格的要求。
