PC (Polycarbonate)

The "Steel of Plastics": Unmatched Impact Strength and Industrial Versatility

Polycarbonate (PC) is a premium engineering thermoplastic renowned for being virtually unbreakable, offering 250 times the impact resistance of glass. To meet the specific rigorous demands of both the industrial and construction sectors in the UK and Benelux, SRT provides this polymer in two specialized formats:

Solid Polycarbonate Sheets for Security and Safety

Solid PC provides glass-like optical clarity combined with the extreme structural toughness required for high-security glazing and industrial machine protection. It is the mandated standard for Machine Guards and Protective Safety Covers and high-load Custom Plastic Components.

Multiwall Polycarbonate Systems for Thermal Construction

Multiwall PC (also known as Twinwall or Multi-chambered sheets) is engineered for superior thermal insulation and lightweight efficiency. These systems are the premier choice for energy-saving architectural roofing, carports, and greenhouses where light diffusion and climate control are essential.

Engineering and Material Selection Guide (Solid vs. Multiwall)

The selection of Polycarbonate depends primarily on whether your project requires structural clarity or thermal insulation. Solid Polycarbonate: A homogenous sheet providing maximum impact strength and glass-like visuals, ideal for [Custom Plastic Components] and security. Multiwall Polycarbonate: A multi-chambered structure designed for lightweight roofing and thermal efficiency in the building sector. Thermal Note: Polycarbonate has an exceptionally high Max Service Temp of 120 degrees Celsius, making it far more heat-resistant than PET or PMMA. For lower thermal requirements, consider PET / APET.

Application Focus Optimized for [Technical Glazing], security screens, roof lights, and safety partitions.
Thermal Limits Continuous service up to 100°C; brief peaks up to 120°C without loss of property.
Surface Finish Solid (Clear or Frosted / Matt, Bronze, Opal, Scratch-Resistant) or Multiwall (Clear, Opal, Solar Control).
Fabrication Options Highly suitable for CNC Milling, Cold Bending, and Vacuum Forming.
Thickness Range Solid sheets from 2mm to 15mm; Multiwall systems from 4mm to 35mm.
