The Pro Poly Advantage
State of The Art Technology and Products
Polyprene is a specially formulated copolymer sheetstock material used in the construction of fire service products. The resin used in making Polyprene is a combination of polyethylene and polypropylene polymers which results in stronger physical properties in either high or low temperature applications. Polyprene will not rust, corrode, dent, crack, chip or peel. Polyprene welds are impervious to microbial attack and meet FDA approval for food grade surfaces. Also, Polyprene is lighter than steel, aluminum or fiberglass in the same application.
Pro Poly of America builds the toughest, most durable tanks in the industry, with a limited lifetime warranty to back them up. Stringent engineering guidelines, highly skilled fabricators and unique production methods like the Bent Edge makes us confident in our products ability to live up to the Pro One Warranty.
What is Bent Edge? It is a patented process, exclusive to Pro Poly, of heating and bending sheet stock to form a continuous, seamless corner void of any joints, therefore eliminating the chance for leaks in these areas. Simply put, there is no stronger way to build a poly fire truck tank than with Bent Edge.
The Pro Lock system is an exclusive and proprietary mechanical locking of all tank and body parts prior to welding. Pro Lock incorporates a mechanical lock and Bent Edge technology into each exterior joint by utilizing a dado to join two parts. The Pro Lock baffle system interlocks the baffle with the tank wall to give superior strength to the tank and body through the entire service life of the tank.
Extrusion welding is one of the core techniques used in plastic fabrication, utilized exclusively at Pro Poly on all external seams because it is one and a half times stronger than a conventional hand weld. Pro Poly of America takes pride in being the only manufacturer of tanks in the industry utilizing this innovative technique. Without proper extrusion welding in key areas, the stress and forces put on a tank might overwhelm a conventional weld.
