English
We often see a kind of colorful and ever-changing decorative material in streets, shopping malls, and retail stores. It looks crystal clear, yet full of shifting rainbow colors.
From different angles, the colors change. Under different lighting, the effect becomes even more stunning.
This material is called acrylic iridescent board, also known as rainbow acrylic sheet.
Its appearance breaks the traditional limitation of single-color acrylic sheets. It brings stronger visual impact and more creative possibilities.
How Acrylic Iridescent Board Works
Strictly speaking, iridescent board is not a single-layer acrylic material.
It uses acrylic as the base sheet. A layer of PET iridescent film is then laminated onto the back side through a heat-press process.
This structure creates a special optical effect.
The color changes depending on viewing angle and light direction.
The colorful effect mainly comes from the rainbow film on the back.
What Is Rainbow Film?
Rainbow film is a multi-layer optical PET film.
It is made by combining PET materials with different refractive indexes.
These layers are melted, extruded, and stacked repeatedly.
The structure contains more than 100 ultra-thin layers.
Each layer is only a few hundred nanometers thick.
The total thickness is about 16–36 microns.
Common types include:
· Red base with green reflection
· Blue base with gold reflection
· Blue base with purple reflection
Different distances, angles, and lighting conditions create different visual effects. The colors constantly shift and flow like a rainbow.
Applications of Acrylic Iridescent Board
Rainbow acrylic is widely used in daily life products and decorative designs.
It helps bring “rainbows into life”.
It can be used for:
· Interior decoration
· Furniture design
· Art installations
· Display props
· Retail visual merchandising
No matter the shape, it shows a vivid rainbow-like shine under different light conditions and viewing angles.
Advantages of Acrylic Iridescent Board
Acrylic has strong processability. It can be:
· Cut
· Polished
· Bonded
· Thermoformed
This allows designers to create many shapes and structures.
Creative products include decorative items such as acrylic spheres, castles, and animal shapes. It is also widely used in functional products like acrylic tables, coffee tables, and chairs.
The possibilities are almost unlimited, combining fashion with practicality.
Manufacturing and Quality Requirements
High-quality acrylic iridescent products go through multiple precision processes, including:
· Cutting
· Polishing
· Coating
· Lamination
During production, strict requirements apply to:
· Transparency
· Density
· Formability
Good anti-aging performance is also essential. High-quality products must resist yellowing over time.
Because of this, choosing a reliable acrylic brand is very important in a competitive market.
