| Material | Average Impact Strength | UV Resistance | Weight (vs. Glass) |
|---|---|---|---|
| Acrylic | Moderate | High | ~50% lighter |
| Polycarbonate | Very High | High (with coating) | ~50% lighter |
Regulatory Environment
Both acrylic and polycarbonate products are subject to industry-specific standards and government regulations that govern their safety and environmental compliance.
Fire Safety and Building Codes
USA (ASTM & NFPA): Materials used in public buildings must meet ASTM E84 for surface burning and NFPA 286 for room corner tests.
EU (EN 13501): Materials must pass fire performance standards before use in construction or transportation sectors.
Environmental Regulations
RoHS (Restriction of Hazardous Substances): In the EU and several other regions, polycarbonate used in electronics must be free from lead, mercury, and other toxic materials.
REACH: The EU's REACH regulation requires full transparency regarding chemical substances used in plastic manufacturing.
Transportation and Safety
FMVSS (Federal Motor Vehicle Safety Standards) in the U.S. regulates materials used in windshields and light covers for durability and impact resistance.

Frequently Asked Questions (FAQs)
1. What is the main difference between acrylic and polycarbonate?
Answer: Acrylic is more rigid and has better optical clarity, while polycarbonate is more impact-resistant and flexible. Acrylic may crack under stress, whereas polycarbonate bends but doesn’t break easily.
2. Can I use acrylic or polycarbonate for outdoor projects?
Answer: Yes, both materials can be used outdoors. Acrylic is naturally UV-resistant and maintains clarity over time. Polycarbonate often requires a UV-protective coating to prevent yellowing and degradation.
3. Is polycarbonate stronger than acrylic?
Answer: Yes. Polycarbonate is about 250 times stronger than glass and significantly stronger than acrylic. This makes it ideal for applications like bullet-resistant windows and safety shields.
4. Can I cut and drill these materials at home?
Answer: Yes. Both materials can be cut and drilled using basic tools, but care must be taken to avoid cracking. Use fine-toothed blades and start with low speeds to prevent overheating.
5. Are acrylic and polycarbonate materials recyclable?
Answer: Yes, but recycling depends on the local facility. Polycarbonate recycling has improved recently due to better sorting technologies. Acrylic is also recyclable, but may require specific chemical recycling processes.
Summary Table: Acrylic vs. Polycarbonate
| Property | Acrylic | Polycarbonate |
|---|---|---|
| Clarity | Excellent | Very Good |
