Molded plastic enclosures can take almost any shape, which is why they are used for hand-held enclosures and enclosures with special features such as battery compartments, recessed areas for labels, DIN rail mounts, and infrared windows. Plastic also allows a more stylish design for plastic enclosure boxes that will be used on a desktop.
Steel and aluminum enclosures have their place, but typically, plastic enclosures are more economical and lighter weight.
Of course, plastic enclosure boxes are immune to corrosion from moisture and provide electrical insulation for the components inside. Many come with clear or translucent covers that provide a big benefit: a worker can inspect the components and read displays without opening the box.
Electronic enclosures can be molded using a wide variety of plastic resins. At Bud, we have found that three common types of plastic are enough to cover nearly every application: polycarbonate, ABS, and ABS/polycarbonate blend. Read the descriptions below before you select a plastic enclosure box.
ABS (acrylonitrile butadiene styrene) plastic is tough, with high impact resistance. However, the walls of the enclosure should not be too thin, because that decreases strength. ABS is generally chemical resistant, and like all plastics, it provides electrical insulation. Its temperature range is moderate: -20 to 80 degrees C. It is flame resistant to UL 94 HB. It doesn’t have UV resistance, so it can’t be used outdoors. It is a low-cost alternative to polycarbonate plastic.
Polycarbonate (PC) plastic has extraordinary impact strength. In fact, it is used for NFL helmets. Its impact resistance stems from its high tensile strength typical of polyester plastics. Another benefit of polycarbonate plastic is that it can be transparent. What’s more, it can often withstand UV light and sometimes be used outdoors, at temperatures from -20 to 140 degrees C. There are drawbacks, however. Oils, alkalis, and alcohols can damage it, and it contains BPA.
A great way to achieve the best of both ABS and polycarbonate plastics is by blending them together. This plastic blend combines the strength and high-temperature capabilities of polycarbonate with the chemical resistance of ABS. It’s a good choice if the enclosure will contact cleaning supplies. This blend achieves the UL 94 V-0, the highest level of flame resistance in a plastic enclosure box.
