（1）由于TPU具有很高的吸湿性，因此在加工前必须完全干燥；）

（2）由于粘度对温度的依赖性较慢，温度控制精度有待提高

（3）螺钉的结构和长宽比应从材料的特性（如压缩比、凹槽深度、L/D等）考虑

（5）成型机的功率设置应稍大（1.5~2倍于通用树脂）

2。与通用塑料和其他热塑性弹性体（TPE）相比，TPU的加工有许多困难。然而，由于成型机和加工技术的改进，各种成型方法可用于生产各种产品

Glass fiber TPU material

Processing and forming:

Forming technology

1. The representative molding processing methods of TPU are extrusion molding and injection molding. These molding methods need to pay attention to the following points:

(1) Because TPU is highly hygroscopic, it must be fully dried before processing;)

(2) Due to the slow dependence of viscosity on temperature, the temperature control accuracy should be improved;

(3) The structure and aspect ratio of the screw should be considered from the characteristics of the material (such as compression ratio, groove depth, L/D, etc.);

(4) Consider the mold structure according to the fluidity of the material (no bow | stuck nozzles, runners, gates, etc.);

(5) The power setting of the molding machine should be slightly larger (1.5~2 times that of general-purpose resin);

(6) Forming and annealing treatment to restore the original characteristics (especially the material that is not completely plasticized).

2. Forming technology and application

Compared with general-purpose plastics and other thermoplastic elastomers (TPE), the processing of TPU has many difficulties. However, due to the improvement of molding machines and processing technology, various molding methods can be used to produce various products.
