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...

why stable MFI is matter for TPU process
Mar 29 , 2024
Stable MFI or MI (Melt Flow Index) is an important factor in TPU (Thermoplastic Polyurethane) processing for several reasons: Process Consistency: MFI represents the flowability of the TPU material during processing. Stable MFI ensures consistent and predictable flow behavior, which is crucial for achieving uniform product quality and avoiding defects or variations in the final product. Ease of Pr...

What transparent of TPU influence for the color appearance of TPU products ?
Oct 31 , 2024
If non-transparent TPU (Thermoplastic Polyurethane) is changed to a transparent form without altering the incorporation of colorants, it can lead to a few potential problems: Inconsistent or altered color appearance:The colorants used in non-transparent TPU are typically designed for its opaque nature. When the TPU becomes transparent, the interaction between light and the colorants changes, which...

What will hardness of TPU may change if reducing the melt index of TPU (Thermoplastic Polyurethane)
Dec 06 , 2024
Reducing the melt index of TPU (Thermoplastic Polyurethane) can indeed affect the hardness of the material, but it's not a direct correlation. The melt index refers to the flowability of the molten TPU during the injection molding process. Generally, a lower melt index indicates a higher molecular weight of the TPU, which can result in increased hardness. This is because higher molecular weight TP...
