In the world of plastics, acrylic and polycarbonate sheets are two of the most popular materials used across various industries. Both have their unique properties and applications, but choosing the right one for your project can be a daunting task. Whether you’re an architect, designer, or hobbyist, understanding the differences between these materials will help you make an informed decision. We aim to compare acrylic sheets with polycarbonate sheets, highlighting their differences, advantages, and ideal applications.
What are Acrylic and Polycarbonate Sheets?
Acrylic Sheets
Often used as a lightweight or shatter-resistant substitute for glass, acrylic, commonly referred to as polymethyl methacrylate (PMMA), is a transparent thermoplastic. Acrylic sheets are known for their clarity, rigidity, and ease of fabrication, making them a favorite among acrylic suppliers and users alike.
Polycarbonate Sheets
Polycarbonate is another transparent thermoplastic, but it’s known for its high impact resistance and durability. It’s often used in applications that require a material stronger than acrylic but still transparent. Polycarbonate sheets are more flexible and stronger than acrylic, making them ideal for more demanding applications.
Differences Between Acrylic and Polycarbonate Sheets
Clarity
Acrylic Sheets: Acrylic boasts superior optical clarity, allowing up to 92% of light to pass through. This makes it the preferred choice for applications where clarity is crucial, such as aquariums, display cases, and signage.
Polycarbonate Sheets: While polycarbonate is also clear, it has a slightly lower light transmission rate of about 88%. This difference is minor but noticeable in applications where maximum clarity is required.
Strength and Durability
Acrylic Sheets: Acrylic is more rigid and can crack under high impact. While it is more shatter-resistant than glass, it’s not as strong as polycarbonate.
Polycarbonate Sheets: Known for its high impact resistance, polycarbonate is virtually unbreakable. It is 250 times stronger than glass and 30 times stronger than acrylic, making it suitable for applications requiring high durability, such as machine guards and protective barriers.
Weight
Acrylic Sheets: Both acrylic and polycarbonate are lightweight compared to glass. However, acrylic is slightly heavier than polycarbonate.
Polycarbonate Sheets: Polycarbonate is about half the weight of glass and slightly lighter than acrylic, making it easier to handle and install in various applications.
UV Resistance
Acrylic Sheets: Acrylic offers excellent UV resistance, making it an ideal choice for outdoor applications like skylights, windows, and outdoor signage.
Polycarbonate Sheets: Polycarbonate is also UV resistant but may yellow over time if not treated with a UV-resistant coating. It’s important to choose polycarbonate sheets with UV protection for outdoor use.
Cost
Acrylic Sheets: Generally, acrylic is less expensive than polycarbonate. Its cost-effectiveness combined with its clarity makes it a popular choice for decorative and display purposes.
Polycarbonate Sheets: Polycarbonate is more expensive due to its higher impact resistance and durability. However, the added cost is often justified in applications where strength and longevity are necessary.
Ideal Applications
Acrylic Sheets
Signage and Displays: Due to its high clarity and ease of fabrication, acrylic is perfect for signs, displays, and point-of-sale stands.
Aquariums and Terrariums: Its excellent optical clarity makes acrylic an ideal material for creating visually appealing aquariums and terrariums.
Home Décor and Furniture: Acrylic’s aesthetic appeal and versatility make it a popular choice for modern home décor items and furniture.
Polycarbonate Sheets
Safety and Security: Due to its high impact resistance, polycarbonate is used in bulletproof windows, machine guards, and protective barriers.
Automotive and Aerospace: Polycarbonate’s strength and lightweight properties make it suitable for automotive headlamps, aircraft windows, and other components.
Building and Construction: Its durability and UV resistance make polycarbonate ideal for greenhouses, skylights, and roofing applications.
