Polycarbonate vs. Plastic: What's the Difference?
By Janet White || Published on December 12, 2023
Polycarbonate is a specific type of strong, durable plastic; Plastic is a broad category of synthetic or semi-synthetic materials.
Key Differences
Polycarbonate is a specific type of plastic known for its strength, durability, and transparency. It's a thermoplastic polymer that is particularly useful in applications where impact resistance and transparency are crucial, such as in safety glasses and bulletproof windows. Plastic, in general, refers to a wide range of synthetic or semi-synthetic materials that are moldable and made primarily from petrochemicals. Plastics encompass a variety of materials, including polycarbonate, but also others like polyethylene and PVC.
Polycarbonate is often chosen for products where toughness is required because it's less likely to crack or shatter compared to other plastics. This quality makes it ideal for use in safety equipment, optical devices, and certain types of packaging. Plastics, on the other hand, can vary greatly in their properties, including flexibility, durability, and resistance to heat and chemicals. This diversity makes them suitable for an enormous range of applications, from disposable containers to high-strength industrial components.
In manufacturing, polycarbonate is valued for its ease of molding and thermoforming, as well as its ability to withstand high temperatures without losing its shape. It's also known for being lightweight yet extremely strong. Plastics, depending on their type, can be engineered to possess a variety of characteristics, including flexibility, transparency, or resistance to wear, allowing for their use in everything from clothing and packaging to automotive and aerospace industries.
Environmentally, polycarbonate can pose challenges due to its non-biodegradable nature and the potential release of bisphenol A (BPA) during decomposition, raising concerns about environmental and health impacts. Plastics, in general, have raised significant environmental concerns, particularly around issues like pollution and recycling. Different types of plastics vary in their recyclability and impact on the environment.
Polycarbonate is a specific, high-performance type of plastic known for its strength and clarity, while plastics as a whole are a diverse group of materials with a wide range of properties and uses.
