Polycarbonate Enclosures Vs. Fiberglass Enclosures


Impact resistanceWhich material is tougher? The average fiberglass enclosure tensile strength is approximately 220 in/lb. Polycarbonate has a tensile strength of 900 in/lb. Polycarbonate is over 4 times the impact resistance of fiberglass.
WeightWhether it is saving on shipping cost or the ability for one person to carry and install a product in an enclosure, weight increasingly is important. Polycarbonate is up to 40% lighter than
UV resistanceFiberglass UV protection is offered as a shield or other coating that attempts to protect the fibers from the inevitable deterioration or even failure of the exterior coating. With polycarbonate, the UV inhibitor is in the formulation and is uniformly integral to the enclosure.
Ease of ModificationFiberglass is tough on tools and often chips while machining leaving sharp, unsightly edges.  Also Fiberglass upon drilling or cutting gives off a very fine dust that is difficult to clean up and is a skin and lung irritant. Integra polycarbonate enclosures are easy to modify, do not give off dust and leave a clean attractive surface with no sharp edges.
Eco-friendlyWhether during the manufacturing process or at the end of the enclosure’s life, fiberglass material cannot be reused and is destined for landfills. Polycarbonate in the manufacturing process or at the end of its’ usable life is recyclable.
Damage from shipping/handlingFiberglass is a very brittle material, to the point that it is at risk from damage anytime it is dropped or mishandled in any way. Because of it’s durability polycarbonate is rarely damaged from shipping or handling.
