Polycarbonate Enclosures & Boxes

Polycarbonate enclosures and boxes are an ideal solution for outdoor commercial and industrial applications. Meeting at least NEMA 4X and IP65 requirements, our polycarbonate cases are UL listed, waterproof and weatherproof. Durable, lightweight, impact-resistant, and UV-stabilized, polycarbonate is a preferred non-metallic material for outdoor electronic and electrical applications. Many of our polycarbonate boxes have a clear cover option for quick visibility of internal components.

What makes polycarbonate enclosures so tough and versatile, and what makes Polycase’s polycarbonate enclosures the gold standard? Read on to explore the features of our polycarbonate models in depth.

Advantages of Polycarbonate Electrical Enclosures

Polycarbonate material is ideal for manufacturing heavy-duty enclosure boxes due to its unique properties, such as:

  • Extremely durable and resistant to impacts
  • Thermoplastic material that can be repeatedly heated and cooled without integrity loss
  • Easy to cut and customize, especially compared to other outdoor enclosure options such as stainless steel and fiberglass enclosures
  • Highly resistant to most types of corrosion
  • Can be manufactured in a variety of formats and shapes, including transparent enclosure covers

Polycarbonate enclosure solutions allow you to apply these characteristics in a huge variety of applications — from junction boxes to control panels to instrument enclosures. For more information on the properties and uses of polycarbonate, see our complete guide to polycarbonate.
