However,when sucha windowis requiredfor application, pleasefollow the guidelines

below.



WindowMaterial

The suitability of window material depends on  the anticipated environment and your

product’s intended use. Appropriate window material includes glass and plastic.

However, if you choose to use plastic, it should havea protectivehard‐coaton at least

theexposedsurface.Amongthemostcommonlyusedwindowmaterialsare:



Acrylic

Acr

ylic is an excellent material option for exit windows at low initial cost. This cellcast

acrylic is a clear plastic that can be used as a shatterproof replacement for glass that

maintainstransparencyforanythickness.

CR‐39 

CR‐39isathermal‐settingplasticproducedbythecell‐castingprocess,an

discommonly

used in plastic eye glasses lenses. CR‐39 has excellent chemical and environmental

resistance, including good surface hardness. Typically it does not require hard‐coating,

but can be hard‐coated for severe environments. CR‐39 has reasonably good impact

resistanceandcannotbeultrasonicallywelded.

ChemicallyTe

Glass is a hard material which provides excellent scratch and abrasion resistance, but

unannealedglassisbrittle.Increasingflexibilitystrengthwithminimalopticaldistortion
