AAA Acrylic
Poly methyl methacrylate or PMMA is a transparent thermoplastic. AAA PMMA sheets are able to withstand harsh weather conditions, including UV radiation. These sheets maintain their optical properties for several years and are suitable for industries such as construction and signage. PMMA’s mechanical and optical properties make it an excellent replacement for glass.
FEATURES
1. Excellent Transparency Surface suitable For Buffing Bright,colourless and Rigid Fixed
2. 92% light transmission
3. Easily moulded
4. Elevated hardness
5. Good mechanical strength
6. Resistant to harsh weather
Anti-Glare
Anti-glare sheets are shatter resistant, lightweight and ideal for glazing. They are suitable for signage, silk-screening and POP displays. The sheet comes with matt finish.
High Impact Strength
Acrylic sheets modified for high impact strength are much harder than normal acrylic sheets or glass sheets of the same thickness. These sheets are suitable for signage, displays,
