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.
