Calvana (2 Pack) Round Acetal Copolymer Rods Features
-
HIGH-QUALITY ACETAL COPOLYMER RODS - Often considered a superior material in comparison to acetal homopolymer (POM-H), acetal copolymer (POM-C) has lower friction, higher impact, and higher chemical resistance, and more dimensionally stable. When a plastic part is called for in a project, acetal copolymer is often the first option especially in parts that require durability and wear resistance like in non-marring fixtures, electrical insulators, and bushings
-
VERSATILE AND DEPENDABLE MATERIAL - Acetal copolymer has applications in a wide variety of industries and niche interests. It is used in string instruments as a dulcimer bridge/nut. It's even used in machining applications as a washer and an arbor material. There are also mandrels made of acetals. Other applications include buffer spacers/pins
-
HIGH MOISTURE RESISTANCE - Among different types of acetals, acetal copolymer has the highest moisture, humidity, and high-temperature resistance. It doesn't easily deteriorate or wear in wet environments. And because it absorbs minimal moisture, acetal copolymer retains its physical properties in different environments
-
ZERO CENTERLINE POROSITY - Centerline or core porosity occurs when the acetal's outer layer solidifies faster resulting in a loss of volume in the rod's core. This is a big issue in acetal homopolymers. Acetal copolymers naturally have lower centerline porosity but with an excellent manufacturing process, it is possible to achieve zero centerline porosity, preventing outgassing and water penetration
-
HIGHLY MACHINABLE - Aside from machining on a lathe, acetal copolymers are easy to cut using power saws and easy to sand using power sanders. As it can withstand high temperatures, this material won't become gummy during the machining process. You can use lathes, milling machines, CNC router systems, drill press, miter saws, band saws, and even hand saws!
About Calvana (2 Pack) Round Acetal Copolymer Rods
Acetal copolymer rods have several advantages over other types of plastic rods and even other types of acetal plastic. It has minimal moisture absorption, high strength and rigidity, abrasion resistance, highly machinable, high dimensional stability, high creep resistance, and no centerline porosity issues. Acetal copolymers, especially the rods also provide better yields, with closer tolerances, and straight lines, highly improving material productivity. Though highly machinable, acetal copolymers need blades with high teeth count to minimize cut marks. It also tends to warp and become gummy and more flexible as it becomes thinner. You also need to adjust to a lower feed rate and work at a low angle on the lathe. Aside from these special considerations, acetal copolymer is easier to handle and machine. As a result of their minimal moisture absorption, acetal copolymer rods have high dimensional stability that makes them perfect for use in close-tolerance machined parts. This includes parts that require both strength and rigidity like close tolerance structural and mechanical parts, electrical components, bearings, and gears. Machined acetal copolymer parts outperform even nylon parts (except on abrasive applications). And with its chemical and solvent resistance, acetal copolymers find numerous applications in both industrial and commercial settings. Manufacturers and hobbyists alike had found numerous and versatile applications for acetal copolymers be it as an alternative for other materials including bearings, bushings, gears, bolts, washers, mandrels, rollers, electrical insulators, and electrical components. There are also surprising applications. One example is as a substitute for wood or bone bridges or nuts on different types of dulcimers. Acetal copolymers are also popular as custom handles for knives and fishing rods. Though often mistaken for Delrin (POM-H), generic copolymers (POM-C) have numerous advantages over their more popular cousin.
