Polyester Enclosures

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. 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.
Hoffman POLYPRO polyester enclosures are lightweight and perform well in applications where harsh chemicals, weather extremes and corrosive environments are present. They provide UV protection and a tight environmental seal.
Allied Moulded fiberglass enclosures are molded with ULTRAGUARD fiberglass reinforced with polyester material. They are designed to insulate and protect electronic components in both indoor and outdoor applications.
