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
Related Applications
Aquatic Applications
Acrylic is a common material for aquariums, especially its transparent nature, which provides better visual effects and makes it easier to view aquatic creatures and conditions. Acrylic’s light transmittance and weight are better than glass, so it is often used as glass replacement of.
Air Delivery System Application
It is a system that uses compressed air to transmit files or objects, which can reduce manual operations and material handling while ensuring the accuracy and timeliness of transmission.
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.
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.
Fence Design Application
This design uses acrylic materials to build fences, replacing traditional brick walls. Its transparent or translucent characteristics allow light to pass through and produce unique visual effects. Although the acrylic fence is transparent, its The materials are generally strong and durable, with good resistance to pressure and impact. This makes it no less safe than traditional fence materials.
