Guangzhou Quanxu Silicon Dioxide For PVC Overlay Film

Feature

Silica dioxide, also known as silica or silicon dioxide, is a commonly used additive in the production of PVC overlay films. 

PVC overlay films are thin plastic films that are applied to various surfaces to provide protection, decoration, or other 

desired properties.

Silica dioxide is added to PVC overlay films to enhance their performance and properties. Some of the benefits of using 

silica dioxide in PVC overlay films include:

1. Improved scratch resistance: Silica dioxide particles help to increase the hardness and scratch resistance of the PVC 

film, making it more durable and resistant to wear and tear.

2. Enhanced clarity: Silica dioxide can improve the transparency and clarity of the PVC overlay film, allowing for better 

visibility of the underlying surface or design.

3. Increased dimensional stability: Silica dioxide helps to reduce shrinkage and warping of the PVC overlay film, ensuring 

that it maintains its shape and size over time.

4. Improved printability: Silica dioxide can enhance the printability of PVC overlay films, allowing for better adhesion of inks 

and coatings and ensuring high-quality printing results.

5. UV resistance: Silica dioxide can provide UV protection to the PVC overlay film, preventing it from yellowing or degrading 

when exposed to sunlight or other UV sources.

Overall, the addition of silica dioxide to PVC overlay films helps to improve their performance, durability, and aesthetic 

qualities, making them suitable for a wide range of applications such as automotive interiors, signage, packaging, and 

laminated cards.
