Types of Acrylic: Extruded vs. Cast

There are two primary types of acrylic sheets used in cover manufacturing: extruded and cast. Understanding the differences between them is essential for matching the material to your application.

Extruded acrylic is produced by pushing molten plastic through a die, resulting in a cost-effective option with consistent thickness. It typically has a slightly textured surface and is suitable for general-purpose indoor displays. However, it is less resistant to chemicals, scratching, and thermal stress compared to cast acrylic.

Cast acrylic is formed by pouring liquid resin between glass molds, yielding a higher-quality sheet with superior optical clarity, durability, and resistance to heat and solvents. It features a glossy, smooth finish and is less prone to chipping during cutting or drilling. While more expensive, cast acrylic is the preferred choice for high-value items, professional displays, and applications requiring long-term reliability.

• Cast acrylic can be polished to restore surface shine if scratched
• Extruded acrylic is easier to thermoform for curved designs
• For large covers, cast acrylic offers better structural stability

Pro Tip: If budget allows, opt for cast acrylic—especially for large covers—due to its superior strength, clarity, and longevity. The initial investment pays off in reduced maintenance and replacement costs over time.
