PMMA VS. PC
Q: Should you choose PMMA acrylic, or PC?
A: Both have their own advantages and disadvantages, mainly need to consider the usage and environment, the following is a comparison table between acrylic and PC for your reference:
A: Both have their own advantages and disadvantages, mainly need to consider the usage and environment, the following is a comparison table between acrylic and PC for your reference:
| ITEM | PMMA (Acrylic) | PC (Polycarbonate) |
| Proportion | 1.19 | 1.2 |
| Impact resistance | Fragile | 30 times stronger than acrylic |
| Transmittance | 92% | 88% |
| Processing temperature | Under 80°C | Under 120°C |
| Water absorption | 0.3~0.4% | 0.1~0.2% |
| Under prolonged UV light exposure | Not easy to yellow |
easy to yellow, Need to add UV absorber layer |
| Flame retardant degree | Low (UL 94 level HB) | High (UL 94 level V0) |
| Selling cost | Ordinary | More Expensive |
Q: What are the advantages of acrylic PMMA?
Transmittance(ASTM D1003)
Rockwell hardness (ASTM D785)
Heat distortion temperature (ASTM
D648)
Bending strength (ASTM
D790)
Weatherability - the extent to which the color changes with exposure time
The extent to which the flexural strength of PMMA varies with exposure time

Algae Cultivation Application
Acrylic material has excellent transparency and can be used as the main material of algae culture tanks. It can provide good light transmittance, enable photosynthesis to proceed efficiently, and contribute to the growth and reproduction of algae.
Interior Design Applications
In interior design, acrylic materials have transparency and modernity and create unique spaces. They can divide the space into different areas while maintaining a sense of transparency, adding layering and design highlights to the space.
Gift Box Application
Acrylic gift boxes are transparent and modern. Transparent acrylic materials can clearly display gifts, increase the visual appeal of gifts, and at the same time enhance the sense of value and quality of gifts.
Kaleidoscope Application
Take the kaleidoscope, for example, which often provides children and adults with a wonderful visual experience, allowing people to enjoy the changes in colors and patterns. In addition, it can also demonstrate the characteristics of light and teach students about the principles of light refraction and reflection.
