Which is the best way to process TPU?

The most frequently used techniques for processing TPU are injection molding, extrusion and blow molding. For all processing types, we recommend the use of modern, energy-efficient machinery and precise controlling to ensure superior results and cost-efficient, environmentally friendly operations.

Why do you need to dry TPU before molding?

Drying is a critical step in ensuring TPU’s process effectively and that a good part is obtained upon molding. If moisture is not removed from the polymer effectively before processing, the material can lose molecular weight in the machine barrel.

How does a Tensor Processing Unit ( TPU ) work?

TPUs have libraries of optimized models, use on-chip high bandwidth memory (HBM) and in each core have scalar, vector, and matrix units (MXUs). The MXUs do the processing at 16K multiply-accumulate operations in each cycle. 32-bit floating point input and output is simplified via Bfloat16.

Can a regrind TPU be used in a melt?

While regrind TPU polymer can be presented in a melt, make note that TPU’s can lose molecular weight as a result of processing. This being the case, reprocessed material could suffer end property loss. If a decision is made to use regrind, recommended levels should not exceed 30% with residence times in the barrel as low as possible.

How is the processing of Covestro’s TPU done?

2. Covestro’s TPU can be processed on the equipment normally used for processing thermoplastics. The most important pro- cessing techniques are: Injection molding Extrusion Blow molding 2.1 Form supplied Covestro’s TPU are supplied as natural-colored cylindrical or lentil-shaped granules.
