Allied Moulded Polycarbonate Enclosures
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.
Allied Moulded non-metallic enclosures are designed to protect against the toughest elements and environments across a wide array of industrial applications. From small junction boxes to large free standing cabinets, the enclosures are designed to insulate and protect electronic components in both indoor and outdoor applications.
Allied Moulded Polycarbonate Enclosures are a durable and aesthetically pleasing alternative to fiberglass enclosures. The AMP Series POLYLINE polycarbonate enclosures offer a variety of sizes and feature configurable solid/opaque or clear polycarbonate cover options along with metal and nonmetal snap latch closure options. The enclosures allow for standard back panel installation and include a provision for an adjustable hinged front panel installation.
Non-Metallic Enclosure Types
Characteristics of non-metallic enclosures:
NEMA 4x rating for outdoor use providing chemical resistance and protection from dust, debris, water and rain.
High insulation value, which provides insulation from cold and hot temperatures, but does not dissipate heat from inside the enclosure.
Non-conductive, meaning components cannot be grounded to the enclosure, but it still provides the same security and tamper resistance levels as metallic enclosures when properly locked.
Types of non-metallic enclosures:
Fiberglass
A thermoset polyester material reinforced with glass fibers. It is the most widely used non-metallic material in the industry. It has high impact strength and rigidity (dimensional stability), a superior working temperature range (-31˚F to 300˚F), excellent electrical properties, moisture and chemical resistance, as well as being cost effective.
Polycarbonate
High-performance thermoplastic resin processed by injection molding or sheet extrusion. It is impact resistant, rigid (dimensional stability), has an extended temperature range (-31˚F to 180˚F), excellent electrical properties, fire retention, UV stability and corrosion resistance in some acidic surroundings. It is not suitable for environments with strong alkalis and organic solvents.
ABS or ABS blends
Acrylonitrile Butadiene Styrene is a common thermoplastic polymer processed by injection molding. It has high impact resistance, but less impact resistance in cold weather compared to polycarbonate, excellent electrical properties, superior chemical and moisture resistance, but a narrower temperature range than fiberglass (-40˚F to 248˚F).
Polyester
High-performance unfilled thermal plastic processed by injection molding. It has high impact resistance, but less impact resistance in cold weather than polycarbonate, excellent electrical properties, superior chemical and corrosion resistance, but a narrower temperature range than fiberglass (-40˚F to 248˚F).
