新的低排放杜邦Delrin 300TE乙酰树脂（POM）是杜邦性能聚合物（Dupont）的第一个撞击改造的POM，可满足汽车行业在车辆室内使用塑料的要求要求。这扩展了在车辆中Delrin actal树脂的应用范围，以在室内装饰中包括塑料组件，其中需要高阻力冲击负载。
杜邦汽车内部材料开发经理Hans-Hermann Kirner表示：“鉴于消费者对质量的需求不断增长，汽车行业为挥发性有机化合物（VOC）排放的限制极低。”“由著名的德国埃顿独立弗雷斯尼乌斯研究所（Fresenius Institute领先的德国OEM，这意味着新材料在该领域的VOC排放方面符合世界上最严格的要求。”
新的Impact修饰和低发射Dupont™Delrin®300TE扩展了POM的应用范围。从广泛的，可见的零件到杠杆和齿轮等小型功能组件，现在还包括在汽车内部的应用，例如在座位区域中，需要对高冲击负荷的抵抗力。
Delrin 300Te融合了Delrin 100T（MFI = 2）之间的熔体流量指数（MFI190/2,16）为6 g/10min，它的差距将高粘度与非常高的冲击力结合在一起，并且中等粘度，Stiffer Delrin 500T 500T 500T 500T（MFI = 12）。
Delrin 300TE比Delrin 300PE更具影响力，Delrin 300PE先前推出的低排放等级也适用于汽车内部。它在23°C的18 kJ/m²（Delrin 300pe：11 kJ/m²）下达到了缺口冲击强度。在-30°C时，新300TE等级的缺口冲击强度仍然高达10 kJ/m²（300pe：8 kJ/m²）。
As with all members of the acetal resin family from DuPont, new Delrin 300TE also combines high strength, hardness and stiffness over a broad temperature range with high abrasion resistance and a low coefficient of friction, a high heat deflection temperature, good electrical and dielectric properties and high dimensional stability.
Kirner补充说：“由于其高熔体流动，薄壁的较薄的部分具有长流路 - 例如，头枕中使用的支柱 - 是Delrin 300te开发的主要领域。总的来说，所有POM等级均适用于低噪声和低摩擦控制和驱动系统。”用于开发精致的小零件的额外的低排放等级。
