(2 Pack) Round Acetal Copolymer Rods - Standard Tolerance 1 ½ -Inch Diameter and 12-Inch Length Opaque Black Acetal Copolymer Rods Meets ASTM D6778 Specifications Perfect for Non-Marring Fixtures

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!
