Overview
Acrylic extruded sheet, or polymethyl methacrylate (PMMA), is a thermoplastic polymer produced through continuous extrusion. Unlike cast acrylic, extruded sheets offer tighter thickness tolerances and are more cost-effective for large-scale production. First commercialized in the 1930s, extruded acrylic combines the optical clarity of glass with superior weatherability and formability. The extrusion process enables efficient production of sheets up to 3 meters wide, making it ideal for architectural and industrial applications.
Physical and Chemical Properties
With 92% light transmission (comparable to glass) and a refractive index of 1.49, extruded acrylic provides exceptional optical properties. Its tensile strength ranges from 50-77 MPa, with a Rockwell M hardness of 85-105. The material exhibits excellent resistance to UV radiation and weathering when properly stabilized. Chemically, it is inert to dilute acids and alkalis but susceptible to strong solvents like acetone. Its thermal deformation temperature is approximately 95°C at 1.82 MPa load.
Main Applications
In commercial signage, extruded acrylic dominates due to its machinability and cost efficiency for laser cutting and routing. Retail displays benefit from its clarity and ability to hold vibrant printed graphics. Architecturally, it serves as lightweight glazing for skylights and noise barriers. Industrial uses include machine guards, cleanroom partitions, and medical device components. The automotive sector utilizes it for tail lights and instrument panels.
Safety and Storage
While generally safe, machining generates fine dust requiring proper ventilation. Sheets should be stored horizontally on flat surfaces to prevent warping, ideally at 15-25°C with <60% humidity. Protective paper or film should remain until fabrication to prevent surface scratches. For fire safety, note that PMMA is combustible (UL94 HB rating) and produces minimal smoke without toxic halogen gases.
B2B Procurement Guide
Key specifications include thickness tolerance (typically ±10%), UV stabilization (3-5 year warranty grades available), and optical quality (optical vs. commercial grades). For large orders (pallet quantities), request factory-direct pricing. Consider lead times (2-4 weeks standard) and minimum order quantities (often 100+ sq ft). Certifications like ISO 9001 and material data sheets should accompany shipments.
