TECAST 6PA cast nylon 6
TECAST™ cast nylon, available in a variety of grades, offers a combination of good mechanical properties, excellent bearing and wear characteristics, and the large-size capabilities of the casting process. Its fatigue resistance, noise damping ability, corrosion resistance, and light weight make TECAST™ ideal for metal replacement applications, such as bearings, gears, sheaves, and sprockets. At one-eighth the weight of bronze, TECAST™ is easier to handle and maintain than metals such as iron, aluminum, brass, and bronze, which it typically replaces in industrial wear applications. Other materials that TECAST™ commonly replaces because of its superior performance are laminated phenolics, elastomers, and wood. TECAST™ has excellent wear and abrasion resistance, resulting in extended component life and lower maintenance cost. Its formulations are readily available in rod, plate, and tube. Nonstandard shapes, such as rings, discs, and blocks can be economically produced in small quantities with short lead times. Custom parts can be cast-to-size or near-net-shape with relatively inexpensive tooling.
- TECAST™ 6PA NATURAL
An FDA-compliant cast type 6 nylon used in applications requiring cast nylon advantages without fillers. - TECAST™ 6PA BLACK
A black cast type 6 nylon that is more UV resistant than 6PA natural. - TECAST™ 6PA BLUE
A blue cast type 6 nylon with properties similar to 6PA. Heat stable but with improved heat resistance properties. - TECAST™ 6PAM
A molybdenum disulfide-filled cast type 6 nylon used for general bearings and wear applications because of its superior strength and hardness. - TECAST™ 6PAG
A graphite powder-filled cast type 6 nylon with properties similar to 6PAM but better suited to wet applications. - TECAST™ 6XAU
A high heat (up to 260°F continuous), weather resistant cast type 6 nylon with superior fatigue-resistance and bearing properties. - TECAST™ 6PAL
An oil-filled cast type 6 nylon used in applications requiring excellent bearing and wear properties where external lubrication is difficult or impractical. It is also available for food grade applications.
Its unique combination of strength, wear resistance, toughness, machinability, and corrosion resistance make TECAST™ cast nylon ideal for bearings, thrust washers, bushings, wear pads, sheaves, rollers, gears, sprockets, and wheels. TECAST™ is commonly used in construction equipment, material handling systems, amusement park rides, pulp and paper processing equipment, steel mills and industrial equipment.
