阻燃TPU Texin 990AR

Texin 990AR resin is a polyether-based thermoplastic polyurethane with a Shore hardness of approximately 90A*. It contains an internal mold releaseadditive. This resin can be processed by injection molding or extrusion.

Properties / Applications:
Texin 990AR resin offers outstanding abrasion resistance, impact strength, toughness, and flexibility. It also exhibits excellent hydrolytic stability, and exceptional mold release characteristics. Texin 990AR natural color resin complies with FDA food-contact regulations 21 CFR 177.1680 (Polyurethane Resins) and 177.2600 (Rubber Articles Intended for Repeated Use), subject to the limitations of these and any other applicable regulations. It is also listed under NSF Standard 61 for use in potable water applications. Typical applications include belting, hose, seals and gaskets, tubing, cable jackets, hose jackets, athletic soles, casters, film, extruded profiles, and miscellaneous molded articles. As with any product, use of Texin 990AR resin in a given application must be tested (including field testing, etc.) in advance by the user to determine suitability.

TPU(热塑性聚氨酯弹性体橡胶)。主要分为有聚酯型和聚醚型之分，它硬度范围宽(60HA-85HD)、耐、耐油，透明，弹性好，在日用品、体育用品、玩具、装饰材料等领域得到广泛应用，无卤阻燃TPU还可以代替软质PVC以满足越来越多领域的环保要求。聚氨酯弹性体是弹性体中比较特殊的一大类，聚氨酯弹性体的硬度范围很宽，性能范围很宽，所以聚气酯弹性体是介于橡胶和塑料的一类高分子材料。

Texin 990AR-介电常数是TPU材质的重要介电属性。这是一个未命名的比率,在电容器板之间布置绝缘材料而不采用真空时,给定电容器的电容增加的系数。因此,该值构成绝缘材料分离电荷能力的度量标准。介电常数与温度和频率相关,在热塑性塑料测试中心(TTC)根据IE(60250确定。TPU测得的介电常数值范围为8.0至4.0。这些值的降低和电阻值一样,与材料硬度有直接关系。聚餸品级的介电常数通常比聚酯品级稍高。测量频率增加时,一个品级显示的介电常数值轻微下降。介电损耗因数是热塑性塑料(TPU)的另一项重要介电特性。该值是绝缘子交变场中吸收能量的度量标准。它与温度和频率相关,在热塑性塑料测试中心(TTC)根据IEC 60250确定。TPU测得的介电损耗直范围为0.10至0.03，该值与硬度成反比,即随着硬度从硬到软(或更有弹性),这个值会逐渐增加。聚醚品级和聚酯品级之间没有明显的差异。分电损耗随着测量频率的增加而增加，
