PC MAKROLON ®
Technical data for PC (polycarbonate) Makrolon ® GP
Advantages:
• Extremely high impact strength
• Wide temperature resistance range
• Good fire protection classification
Makrolon ® GP are clear, polished, UV-stabilised polycarbonate
boards. They provide an extremely high impact strength, which
exceeds the physical properties of their class. Makrolon ®
solid boards are temperature-resistant in the range -100 °C to
+120 °C, are visually very clear and have a good fire protection
classification.
Makrolon ® GP clear 099 is a clear board with a high degree of
transparency.
Makrolon ® UV clear 2099 is a clear, transparent board with UV
protection.
Makrolon ® NR clear 099 is a transparent board with a matt antireflective
coating and enhanced UV protection on one side.
Makrolon ® GP white 130 and white 150 are white, translucent
boards with good light scatter.
Makrolon ® GP umbra 775 are translucent boards of a brownish
colour.
Makrolon ® FR clear 099 is a colourless, transparent board with an
enhanced fire protection classification, tested to UL 94.
Makrolon ® FG clear 099 is a colourless, transparent board for use
in the food industry and the medical sector.
Applications:
Makrolon ® GP boards are incredibly well suited for use as machine
protectors, lamp covers, signs and billboards, as well as wall separating
elements and door glazing.
The boards are extremely impact-resistant and provide outstanding
protection against wilful destruction. Makrolon ® GP boards can
be hot formed, cold bent and are easy to process.
