Polycarbonate–LEXAN | Makrolon

Technical Data Sheet – Polycarbonate (Pc)

Polycarbonate (PC) is similar to glass and acrylic in clarity but has a significantly higher impact resistance. It is frequently used in machine guarding and security applications that require optical clarity and stronger resistance to breakage. Polycarbonate is lightweight, stiff, and relatively easy to saw, machine, heat form, and paint. It also comes in a variety of colors and grades, including flame-retardant, bullet-resistant, FDA-compliant, structural foam-grade, and glass-filled grades for maximum strength.

Industry trade names: AZCARB, CYROLON, LEXAN, MAKROLON, MARGARD, POLYCAST, POLYGAL, TUFFAK, ZELUX

Common Applications

  • Machine guarding
  • Windows, windshields, and window well covers
  • Power tool and appliance housings
  • Skylights and architectural glazing
  • Security glazing
  • Indoor and outdoor signs
  • Greenhouse glazing (twin-wall grades)

 

Characteristics of Polycarbonate (PC)

  • Impact resistant
  • Heat and flame resistant
  • High clarity
  • Wide temperature range
  • High toughness and dimensional stability
  • Resistant to moisture, humidity, greases, and most acids

ERIE INDUSTRIAL PLASTICS PROVIDES PLASTIC LINE BENDING SERVICES WITH HRK 125 SERIES LINEAR HEATER

Erie Industrial Plastics currently operates an Edge Finisher HRK125 series linear heat table for bending. With the HRK125, EIP can produce seamless bends for all types of plastic products, including:

  • Display cases
  • Machine and food processing guards
  • Equipment covers and guides
  • Protective housing units
  • Tray and storage organizers

HRK 125 SERIES LINE BENDING MACHINE—THE ADVANCED MODEL WITH TOP AND BOTTOM HEATING ELEMENTS

The HRK125 series line bender features double-sided heating, adjustable heating wires built into a steel frame, and a programmable timer that automatically releases to provide consistent top and bottom heating. The bending table provides close tolerance plastic bending without any pretreatments and tight radius edges for crisp bends. This equipment is ideal for a variety of materials, including acrylic, ABS, polycarbonate, kydex, copolymer polypropylene, and PETG.

After the line bender heats the material, it is positioned on a JIG to bend to the required dimensions and held together with weights or JIG clamps. The HRK125’s accessories offer various extension options, specially made fixtures, underframes, and foil bending profiles. For more about EIP’s HRK 125 Series, see the video below.
