Material Comparisons

CFT^™ materials combine the best of engineered thermoplastics with the design stability of metallic materials. The typical material and processing capabilities innate in plastic extrusion is combined with the superb mechanical and physical properties only fiber reinforced pultrusions have been able to attain.

inSERT Technology

Localize high modulus materials within simple or complex extruded shapes, allowing for true design flexibility by inserting CFT^™ materials only where needed within the profile geometry.

Complex Extruded Profiles

Application areas for complex extruded profiles focus on two primary areas: first, applications for replacing extruded thermoplastic materials that cannot meet structural or other mechanical requirements. Second, ideal applications for CFT^™ materials are applications where metallic extrusions are not ideal due to corrosion, weight, or durability.

When designing with CFT^™ materials for the fenestration community, two options present themselves with respect to product design. The first option is a pure CFT^™ profile resulting in a 100% CFT^™ material across the entire cross-sectional area. The second option is perhaps the most potent design approach - a CFT^™ stiffened application. This approach in-situ integrates a CFT^™ material, whether in the form of a rod, angle or flat into a lower strength and typically lower cost thermoplastic. The result is a profile that has high strength continuous fibers oriented only where needed throughout the profile.

As an example, in a rectangular profile measuring 2" x 4" x 0.160" where stiffness and cost reduction of the profile is of primary concern, four 0.070" diameter CFT^™ rod reinforcements can be placed in each corner of the PVC extrusion. While maintaining the same 0.160" wall thickness, the CFT^™ reinforcements will increase the stiffness of the profile by 30-45% with minimal increase in cost. With this increase in performance, it is then possible to look at decreasing the wall thickness of the PVC wall to evaluate cost savings. While maintaining the same stiffness of the original PVC extrusion, the CFT^™ stiffeners can reduce the amount of PVC used. In the rectangular profile, PVC usage can be creased over 35% while maintaining the same part stiffness.

Material Handling Rollers

Conventional material handling systems have used metal or aluminum rollers as the transportation medium in large material handling and packaging systems. These metallic rollers are less than desirable solutions as they are heavy, can be prone to corrosion in food processing or various packaging environments, loud, and energy inefficient. The other material of choice has typically been an extruded thermoplastic, which simply does not have the strength requirements for the repeated stress and strain of a material handling system. Polygon's line of material handling rollers, PolyRoll, offer significant performance enhancements over either metallic or engineered thermoplastic materials.

For the material handling market, increasing noise abatement issues driven from new OSHA regulations have mandated that alternative materials be evaluated which can eliminate metal on metal contact. In addition, the CFT^™ material has a co-extruded thermoplastic polyurethane cover, which significantly improves durability and has inherent abrasion resistance. Overall, the energy required to drive the roller system also decreases due to the fact that the CFT^™ rollers have much lower moments of inertia than conventional metals.

Toughness:

Producers of highway sign posts and delineator posts have for some time sought a material that is high strength and more damage tolerant than current metal, fiberglass and plastic products. CFT^™ products take advantage of the high strength, impact resistance, flexibility and ability to "spring" back into position. Door manufacturers can now look at ways of improving impact resistance and energy absorption of current door systems by strategically placing a reinforcing bar of Polygon's CFT^™ composite on the interior of the door panel.
