Feature
Silica Powder is commonly used as a filler material in transparent PET film sheets. It helps improve the mechanical properties
and transparency of the film. Silica powder is added to the PET resin during the manufacturing process, and it disperses evenly
throughout the material.
The addition of silica powder to PET film sheets offers several advantages. Firstly, it enhances the film's tensile strength and
flexibility, making it more resistant to tearing and breaking. This is particularly important for applications that require high
durability, such as packaging materials or protective films.
Secondly, silica powder improves the transparency of PET film sheets. It helps reduce haze and enhances the film's clarity,
making it suitable for applications that require excellent optical properties, such as display screens or windows.
Additionally, silica powder helps reduce the shrinkage of PET film sheets during processing, resulting in better dimensional
stability. It also improves the heat resistance of the film, allowing it to withstand higher temperatures without deforming or
melting.
Overall, the addition of silica powder to transparent PET film sheets enhances their mechanical properties, transparency, and
dimensional stability, making them suitable for a wide range of applications in various industries.
