The nature of these composites requires them to be completely opaque, on both the top and bottom layers, so use is limited to non-backlit requirements.

18、 Several custom sheet extruders offer variations of weather-resistant ABS for your consideration, and though many sign manufacturers do not perform inhouse thermoforming, ABS is very familiar to custom thermoformers, and partscan be easily sub-contracted.ConclusionThe key to successfully incorporating any material into your sign design is, as it always should be, stringent testing of the prod
