Product Description, Applications
The MAKROLON® polycarbonate sheet manufactured by Sheffield Plastics is hundreds of times stronger than glass, and just as clear. It is also stronger than acrylic sheet, has high impact strength, and is cost-effective and energy-efficient. MAKROLON polycarbonate sheet is ideal for almost any glazing application, including:

• Transportation glazing
• Barrel vaults
• Covered walkways
• Privacy glazing
• Institutional glazing
• Skylights
• Storefronts
• Factory overglazing

MAKROLON polycarbonate sheet comes in several grades to suit any performance requirement.

MAKROLON GP
MAKROLON GP polycarbonate sheet is a high-performance, all-purpose glazing material for general glazing and industrial applications. It is available in clear, colors, and privacy patterns.
