What is Solid Polycarbonate?
Solid polycarbonate is a high-performance thermoplastic material engineered for maximum durability and optical clarity. Unlike multiwall polycarbonate which has hollow internal chambers, solid polycarbonate is a single continuous sheet with no voids—delivering superior impact resistance and light transmission.
Material Composition
Solid polycarbonate is manufactured from polycarbonate resin through an extrusion process. The material can be formulated with different properties:
- Standard Grade: General-purpose applications
- UV-Protected Grade: Coextruded UV-blocking layer for outdoor use
- Impact-Modified: Enhanced safety for high-risk environments
- Abrasion-Resistant: Hard coatings for heavy-use applications
- Tinted/Colored: Available in clear, bronze, grey, opal, and custom colors
How It's Made
The extrusion process creates sheets of consistent quality:
- Polycarbonate resin is melted at precise temperatures
- Molten plastic is forced through shaped dies to form sheets
- For UV-protected versions, protective layer is coextruded simultaneously
- Sheets are cooled and cut to standard sizes (typically 2050mm x 3050mm)
- Quality checked for thickness, clarity, and defects
Key Features & Specifications
???? Impact Resistance
Solid polycarbonate is 250 times more impact resistant than glass. It can absorb massive force without breaking, cracking, or shattering. This is why it's used for bank windows, riot shields, and protective barriers where safety is paramount. Impact strength varies by thickness: 2mm sheets resist moderate impacts, while 10mm+ sheets withstand severe trauma.
???? Optical Clarity
88-90% light transmission means solid polycarbonate is nearly as clear as glass. Thinner sheets (2-4mm) are completely transparent, while thicker sheets may have slight haze depending on formulation. The material maintains clarity without yellowing when UV-protected, making it ideal for applications requiring pristine visibility.
⚖️ Lightweight (1/6th Glass Weight)
A 10mm solid polycarbonate sheet weighs approximately 2.4 kg/m², compared to 25 kg/m² for equivalent glass thickness. This dramatic weight difference reduces structural requirements, simplifies installation, and lowers transportation costs—making projects faster and more cost-effective.
☀️ UV Protection & Durability
Coextruded UV-protective layer prevents yellowing, brittleness, and light degradation. With proper UV protection, solid polycarbonate lasts 10-20+ years outdoors. Without UV protection (for indoor use), sheets can last indefinitely. This makes it ideal for greenhouses, pergolas, exterior glazing, and architectural applications.
????️ Weather Resistance
Solid polycarbonate maintains integrity in extreme conditions: -40°C to +120°C temperature ranges, heavy rain, snow loads, hail impacts, salt spray, and intense UV. It won't crack, warp, or degrade like acrylic or other plastics, making it the preferred material for demanding outdoor applications worldwide.
✂️ Fabrication-Friendly
Unlike glass, solid polycarbonate can be cut, routed, drilled, bent, and thermoformed on site with standard tools. This design flexibility enables custom solutions: unique shapes, curved panels, integrated frames, and site-specific modifications—all impossible with brittle glass.

Frequently Asked Questions
What is solid polycarbonate and how is it different from multiwall?
Solid polycarbonate is a single continuous sheet with no hollow cores, while multiwall has internal ribs creating air pockets. Solid is optically clearer (88-90% vs 85% light transmission), far more impact resistant, and better for applications requiring maximum visibility and durability.
How long do solid polycarbonate sheets last?
With UV protection, 10-20+ years outdoors. Indoor applications last indefinitely. The coextruded UV layer prevents yellowing and maintains structural integrity. Actual lifespan depends on climate, maintenance, and environmental factors.
Is solid polycarbonate safer than glass?
Yes. Solid polycarbonate is 250 times more impact resistant than glass, won't shatter into dangerous fragments, and meets safety standards (ASTM D3763). It's ideal for schools, hospitals, public areas, and any safety-critical application.
Can solid polycarbonate be used outdoors?
Absolutely. UV-protected solid polycarbonate is designed specifically for outdoor applications including roofing, glazing, and weather-exposed structures. It resists yellowing, cracking, and degradation from sun and harsh weather for 10-20+ years.
How much does solid polycarbonate cost compared to glass?
Initial material costs are typically similar or slightly higher. However, lifetime cost is dramatically lower due to: longer lifespan (10-20+ years vs 10-15 for glass), lower installation costs (lighter weight, faster labor), minimal maintenance, and superior durability. ROI typically achieved within 3-5 years.
What thicknesses are available?
Solid polycarbonate is available from 2mm to 20mm, with common thicknesses being 2mm, 3mm, 4mm, 6mm, 8mm, 10mm, 12mm, 16mm, and 20mm. Thicker sheets provide greater impact resistance and load-bearing capacity. Thinner sheets (2-4mm) are ideal for display cases and light glazing.
Is solid polycarbonate recyclable?
Yes, fully recyclable. Solid polycarbonate can be reprocessed into new products or materials, making it environmentally responsible compared to many alternatives. This supports circular economy principles and reduces your carbon footprint.
Can solid polycarbonate be cut and fabricated on site?
Yes. Solid polycarbonate can be easily cut with standard tools (circular saw, jigsaw, bandsaw), drilled with normal drill bits, routed, and thermoformed with heat. This design flexibility enables custom sizing and fabrication to meet specific project requirements on site.
