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...

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 ...
