Non Metallic Electrical Enclosures

ABS enclosures are made of Acrylonitrile Butadiene Styrene, a thermoplastic. ABS is a low-cost option for indoor and moderately corrosive environments where a rating is not required. ABS plastic is impact resistant, chemical resistant to some acids and alkalis and can handle a temperature range from 0 to 176 degrees Fahrenheit.

Fiberglass enclosures are made of a thermoset polyester reinforced with glass fibers. Fiberglass can be installed in environments that are constantly wet and is a low-cost alternative for corrosive environments. Fiberglass is impact resistant, chemical resistant and can handle a wide temperature range of -31 degrees Fahrenheit to 300 degrees Fahrenheit.

Polycarbonate enclosures are made of a thermoplastic resin processed by sheet extrusion or injection molding. Polycarbonate is resistant to corrosion and some acidic environments, however, it is sensitive to abrasive cleaners and should not be around organic solvents and alkalis environments. Polycarbonate is impact resistant and has a temperature range of -31 degrees Fahrenheit to 180 degrees Fahrenheit.

Polyester enclosures are made of unfilled thermal plastic processed by injection molding. Polyester can provide sufficient protection in outdoor and indoor applications, however, sunlight may cause slight yellowing of the material. Polyester is impact resistant, chemical resistant and water resistant. The temperature range is -40 degrees Fahrenheit to 248 degrees Fahrenheit, however, impact resistance is compromised in cold temperatures.
