What is TPP-free TPU material
Dec 13 , 2024
TPP (Triphenyl Phosphate) is a commonly used phosphoric ester additive known for its flame retardant and antioxidant properties. However, in some conditions, TPP may release phosphoric ester smoke and toxic gases, posing potential hazards to the environment and human health. In the applications that involving frequent contact with the human body, such as medical devices and baby products, the use ...

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...

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...
