OMEGA-GARD ® POLYCARBONATE
SHEET, ROD AND TUBE
OMEGA-GARD ® Polycarbonate is a high molecular weight, amorphous engineering thermoplastics. It has a wide useful temperature
range retaining its tough characteristics to below -50ºC whilst at the other extreme it displays a very respectable deflection temperature
of 137ºC at 1.8 MPa. MEGA-GARD® Polycarbonates are characterized by an excellent combination of toughness, transparency, heat
and flame resistance and dimensional stability. The insulating and other electrical characteristics of OMEGA-GARD ® Polycarbonate is
excellent and almost unchanged by temperature and humidity conditions.
MAIN ADVANTAGES OF OMEGA-GARD ® POLYCARBONATE SHEET, ROD AND TUBE
• Light transmission at 87% - colour- clear
• Excellent impact strength (250 x stronger than standard glass on impact, 30 x that of acrylic)
• Excellent sound attenuation and thermal insulation

MAR RESISTANT SHEET OMEGA-GARD ® MR10
OMEGA-GARD ® MR10 polycarbonate sheet is a transparent UV and mar resistant glazing material for flat applications only. The
intrinsic properties of OMEGAGARD ® MR10 combined with its dual hard coated surface provide:
• High impact strength and forced entry protection
• Graffiti resistance
• Excellent all weather performance
• Unique 10 year warranty against breakage and 5 year warranty against yellowing, loss of light transmission and coating failure.
Due to its Mar resistant coating, OMEGA-GARD ® MR10 polycarbonate sheet cannot be cold formed or heat formed. It is intended for
flat applications only.
Tested for abrasion resistance, OMEGA-GARD ® MR10 Polycarbonate exhibits significantly less hazing than uncoated polycarbonate
sheet. The unique coating also provides immunity to many chemicals. Surface contact tests with a wide range of chemicals have
proven to have no effect on impact resistance during falling dart testing, proving the excellent fit for this product in industrial or
aggressive environments. In applications where the product will come into contact with aggressive chemicals, specific testing of the
material is always advised.
For some applications the ripple orientation may play an important part in the optical performance of the sheet. This orientation is
marked with a continuous ribbon applied to the sheet masking.

LIGHT TRANSMISSION
Transparent OMEGA-GARD ® Polycarbonate sheet have excellent light transmission, between 84% and 87%. However, for buildings in hot
climates or with north facing aspects, it is available in translucent colours and opal white. It is essentially opaque to all wave lengths below 385
nanometres. This useful shielding property can prevent discolouration of sensitive materials placed under or behind it. Bronze, grey and opal white
coloured polycarbonate sheet significantly reduce solar heat gain, cuts down the brightness of sunlight to a pleasant level, helping to maintain
comfortable interior building temperatures.

THERMAL INSULATION
Considerable cost savings can be achieved by preventing excessive heat loss when using OMEGA-GARD ® Polycarbonate sheet as single or in
combination with, glass. OMEGA-GARD ® Polycarbonate as internal or external glazing can improve the burglary resistance and can protect
against vandalism.

Most common building materials are sealants, gaskets and various cleaning materials. Silicone sealants and neoprene or EPDM gaskets are generally
recommended for use with OMEGA ® GARD polycarbonate sheet. It is strongly advised that when using glazing compounds or cleaning media to
check compatibility before use.
OMEGA-GARD ® Polycarbonate sheet can be cut and sawn easily and accurately using standard woodworking equipment. The sheet must always
be securely clamped to avoid undesirable vibration and rough cut edges. The protective masking should be left on the sheet to prevent scratching and
other surface damage. OMEGA-GARD ® Polycarbonate sheet can be easily cold formed into gentle curves of 175 times the sheet thickness. It can
also be cold line bent under an angle of maximum of 90° using hydraulic workshop equipment.
THERMAL EXPANSION ALLOWANCE
Since OMEGA-GARD® polycarbonate sheet has a large linear thermal coefficient of expansion than that of the glazing profiles
commonly used; care should be taken to allow free expansion of the sheet to avoid bowing. In general, thermal expansion of the sheet
is approximately 3mm per linear metre.
WET GLAZING – OMEGA-GARD® polycarbonate sheet can be glazed using normal standard metal or window frames in
combination with glazing tapes and elastomeric glazing compounds e.g. silicone sealant.

DRY GLAZING – the advantage of dry glazing is that the rubber gaskets snap fit into the glazing bars which allows free movements
of the sheet during expansion and contraction.

CURVED GLAZING – OMEGA-GARD® polycarbonate sheet can be easily cold formed into gentle curves of 175 times the sheet
thickness.
CLEANING – For small areas wash sheet with a solution of mild soap and lukewarm water, using a soft cloth or sponge. For larger
areas clean surface with a high pressure water and/or steam cleaner. Do not use abrasive cleaners or detergents or sharp instruments
which may scratch.
