产品详细信息

TPU抗静电耐磨颗粒

在TPU合成过程中，在加工过程中，极小的测量波动和极小的挤出机或辊温度波动足以导致熔体产生凝胶颗粒，无法生产出均匀光滑的产品

合成TPU时，使用混合扩链剂（如乙二醇、丙二醇、己二醇、二甘醇、二丙二醇、HQEE等）不仅可以提高熔体的流动性，还可以减少凝胶颗粒的产生。因此，合成的TPU具有更宽的加工温度范围，并且降低了对加工机械的要求

Product Details

TPU antistatic wear-resistant particles

In the TPU synthesis process, the extremely small measurement fluctuations and the extremely small extruder or roll temperature fluctuations during processing are enough to cause the melt to produce gel particles and fail to produce a uniform and smooth product.

When synthesizing TPU, the use of mixed chain extenders (such as ethylene glycol, propylene glycol, hexylene glycol, diethylene glycol, dipropylene glycol, HQEE, etc.) can not only improve the fluidity of the melt, but also reduce the gel particle produce. As a result, the synthesized TPU has a wider processing temperature range, and the requirements for processing machinery are reduced.

TPU antistatic wear-resistant particles

The ratio of main chain extender/co-chain extender in the mixed chain extender is a key factor. -Generally, the amount of co-extension agent should not be higher than 10% of the total amount of chain extender (generally controlled in the range of 92/8-95/5 is better), otherwise the softening point will decrease more and the shrinkage will increase.
