Acrylic Stock Shapes

Applications and Properties of Acrylic Profiles

A line of stock Acrylic Profiles is available from PETRO for a wide variety of applications including P.O.P. display assemblies. Most items are available in crystal clear general purpose Acrylic as well as impact-modified DR® grade. Some of the many properties of our high quality shapes are:

• Excellent optical light trans-mission (92% in general purpose grades)
• Excellent resistance to sunlight and UV to withstand yellowing
• Ease of fabrication makes it the most economical thermoplastic available
• Superior chemical resistance
• General purpose or impact modified grades

Acrylic profiles from Petro Extrusion Technologies are crafted from impact-modified acrylic (PMMA) with a specific gravity of 1.16, offering a lightweight yet durable solution for various applications. These profiles boast excellent optical clarity with a light transmission of 92%, making them ideal for display cases, lighting fixtures, and decorative elements where aesthetics are key. They are weather-resistant, maintaining stability under UV exposure, and have a tensile strength of 9,000 psi, ensuring structural integrity. With a heat deflection temperature of 175°F at 264 psi and low moisture absorption (0.3% in 24 hours), acrylic profiles resist warping in humid conditions, providing a reliable, long-lasting option for both indoor and outdoor use.

Acrylic Profile Capabilities

Petro Extrusion Technologies supplies a dedicated line of acrylic stock shapes engineered for clarity, rigidity, and long term environmental stability. These profiles are produced using controlled extrusion methods that maintain optical quality and dimensional accuracy across every Z bar, W bar, and channel configuration. Available in both general purpose and impact modified grades, the line supports applications where visual presentation, UV resistance, and clean edge definition are essential.

Optical and Mechanical Performance Characteristics

Acrylic profiles deliver a combination of transparency, surface hardness, and weatherability that makes them suitable for both indoor and outdoor installations. The material’s inherent clarity supports applications where visibility, illumination, or product presentation is a priority. Impact modified grades provide additional toughness for environments where components may experience handling, vibration, or repeated assembly cycles.

Acrylic performance advantages include:

• High light transmission for display and signage applications
• UV stability that resists yellowing and surface degradation
• Surface hardness that maintains clarity under routine contact
• Low moisture absorption for dimensional consistency
• Heat deflection performance suitable for moderate temperature environments
• DR (Impact Modified) Frosted Acrylics that offer high light transmission while offering light diffusion for high end lighting applications

These characteristics support reliable performance across a wide range of commercial and industrial uses.

Profile Geometry and Fitment Options

Petro’s acrylic stock shapes include Z bars, W bars, and channels designed to interface cleanly with panels, slatwall systems, and display structures. Each profile is extruded with precise corner angles and uniform wall thickness to ensure consistent fit and alignment. Lengths are supplied in standard six foot sections, with select items available for custom order depending on grade and geometry.

These geometries support applications such as edge retention, panel mounting, product display framing, and protective covers.

Material Grades and Selection Considerations

Acrylic stock shapes are available in general purpose (GP) and impact modified (DR) grades. GP acrylic offers maximum clarity and cost efficiency, while DR acrylic provides enhanced toughness for applications requiring additional impact resistance. Petro assists customers in selecting the appropriate grade based on environmental exposure, handling requirements, and mechanical loading.

FAQ

What Is the Difference Between GP and DR Acrylic?

GP acrylic provides maximum clarity and cost efficiency, while DR acrylic offers increased impact resistance for applications requiring added durability.

Are Acrylic Profiles Suitable for Outdoor Use?

Yes. Acrylic’s UV stability and weather resistance make it suitable for outdoor signage, displays, and protective covers.

Can Acrylic Profiles Be Cut or Machined?

Acrylic can be cut, drilled, and fabricated using standard plastic machining methods, allowing easy integration into custom assemblies.

Which Applications Benefit Most from Acrylic Stock Shapes?

Retail displays, lighting components, viewing windows, and slatwall systems commonly use acrylic profiles due to their clarity and surface hardness.
