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.

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.
