How to packing E-TPU (Expanded Thermoplastic Polyurethane) granules can maximize the space utilization of container
Mar 01 , 2024
To maximize the space utilization and load as much E-TPU granule as possible in a 40" container, you can consider the following packing method: Use bulk bags (also known as FIBCs or super sacks): These large, flexible bags are commonly used for storing and transporting granular materials. Opt for high-capacity bulk bags that can hold a significant amount of E-TPU granule. Optimize bag size: Choose...

The proportion of MDI influence the embrittlement performance of TPU at low temperatures
Nov 03 , 2023
MDI is one of the key components used in the production of TPUs. It serves as the isocyanate component, reacting with polyols to form the polyurethane segments of TPU. The selection of MDI type and the ratio of MDI to polyols can affect the physical properties and performance characteristics of the TPU, including its low-temperature behavior. TPU formulated with a higher proportion of MDI generall...

Why the lower TPU hardness the lower processing temperature
Sep 08 , 2023
The processing temperature of TPU is influenced by several factors, including its hardness. Generally, lower hardness TPU grades have a lower processing temperature compared to higher hardness grades. This relationship can be attributed to the following reasons: Molecular Structure: The hardness of TPU is determined by the ratio of rigid segments (hard segments) to flexible segments (soft segments...
