改性TPU塑料颗粒

决定TPU可塑性的重要因素是聚合物的流动性。影响TPU流动性的因素很多。玻璃化转变温度（Tg）、熔融温度（Tm）、分子量和结晶度尤其重要。为了提高TPU的流动性，考虑到这些方面，主要采用以下方法

1。在批量生产中添加催化剂

，由于无法获得高效混合，高效催化剂会导致反应混合物产生“热点”，使产品反应不均匀，造成加工困难

在双螺杆连续法合成TPU的过程中，由于反应器具有高效的喷嘴面积（Mx2om01）和良好的混合效果，采用高效催化体系可以使反循环按九倍财富法生产效率明显提高

催化剂的加入不仅可以加速反应，而且会影响TPU的结晶度等形态和结构。在相同的反应条件和原料条件下，增加催化剂用量可以降低TPU的结晶度，提高熔体的流动性。但当催化剂用量高于设定值时。在这种情况下，TPU的可加工性将产生负噪声，这将使所制备的薄膜的稳定性和均匀性较差

因此，催化剂的选择和催化剂添加量的控制是关键因素

Product Details

Modified TPU plastic particles

The important factor that determines the moldability of TPU is the fluidity of the polymer. There are many factors that affect the fluidity of TPU. The glass transition temperature (Tg), melting temperature (Tm), molecular weight and crystallinity are particularly important. To improve the fluidity of TPU, Considering these aspects, the main methods adopted are as follows.

1. Add catalyst

In batch production, because high-efficiency mixing cannot be obtained, high-efficiency catalysts will cause the reaction mixture to produce “hot-spots”, making the product react unevenly and causing difficulties in processing.

In the process of synthesizing TPU by the twin-screw continuous process, because the reactor has a high-efficiency nozzle area (Mx2om01) with good mixing effect, the use of high-efficiency catalytic system can make the reverse circle by the number method of nine times fortune in The production efficiency is obvious.

The addition of catalyst can not only accelerate the reaction, but also affect its morphology and structure such as the crystallinity of TPU. Under the same reaction conditions and raw materials, increasing the amount of catalyst can reduce the crystallinity of TPU and improve the fluidity of the melt. But when the amount of catalyst is higher than the set value. In this case, the processability of TPU will produce negative noise, which will make the stability and uniformity of the produced film poor.

Therefore, the choice of catalyst and the control of the amount of catalyst added are key factors.
