What transparent of TPU influence for the color appearance of TPU products ?
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 can result in an inconsistent or altered color appearance. The color may appear less vibrant or distorted, and the intended hue may not be achieved.
Loss of opacity: Non-transparent TPU is engineered to block or reduce the transmission of light, resulting in its opacity. When it becomes transparent, light can pass through more easily, leading to a loss of the desired opacity. This can be problematic if the material's intended purpose requires a certain level of light blocking or privacy.
To overcome these problems, manufacturers would need to modify the colorant formulation for transparent TPU. They would typically use transparent colorants specifically designed for transparent materials to achieve the desired color appearance. Additionally, adjustments may be needed in the material's composition and processing parameters to address changes in properties such as opacity and compatibility with surrounding.
