Delrin Acetal Homopolymer Bar USA SEALING White 12x1x0.5 Plastic Bar

Description

Product Overview

The Delrin Acetal Homopolymer Bar from USA SEALING is engineered for demanding industrial and scientific environments where precision, durability, and consistency are paramount. Constructed from a high‑grade acetal homopolymer (commonly known as Delrin), this bar offers an opaque white finish that not only provides a clean aesthetic but also enhances visibility during machining and assembly. Measuring 12 inches in length, 1 inch in width, and a half‑inch in thickness, the bar balances substantial material volume with manageable weight, weighing just 4.16 ounces. Its tensile strength of 9,600 psi, impact resistance of 1.2 ft‑lb/in, and a low coefficient of friction (approximately 0.2) make it an exceptional choice for components that must endure repetitive stress while maintaining dimensional stability. The material’s water absorption rate of only 0.25% ensures that moisture does not compromise performance, even in humid or wet conditions.

Usage

This acetal bar excels in a variety of applications where precision engineering is required. It is frequently employed in the fabrication of precision gears, bushings, and bearings due to its excellent wear resistance and low friction characteristics. The material’s ease of machining allows manufacturers to achieve tight tolerances with standard CNC equipment, making it suitable for both prototype development and high‑volume production runs. In addition to mechanical components, the bar can serve as a structural element in custom fixtures, jigs, and test rigs where rigidity and stability are essential. Its temperature tolerance ranging from -20 °F to 180 °F enables reliable operation in both cold storage environments and moderately heated processes. The bar’s chemical resistance also makes it appropriate for use in applications involving exposure to oils, solvents, and cleaning agents.

FAQ

What is the recommended machining speed for this acetal bar?

For optimal results, use a cutting speed of 300–400 surface feet per minute (SFM) with a sharp carbide tool. Adjust feed rates based on the specific geometry of the part to maintain surface finish quality.

Can the bar be used in high‑temperature applications?

The material is rated for continuous use up to approximately 180 °F (82 °C). For intermittent exposure to higher temperatures, it can tolerate short‑term spikes, but prolonged operation above this range may affect mechanical properties.

Is the white color purely aesthetic, or does it affect performance?

The white, opaque finish does not impact the mechanical performance of the acetal. It primarily aids visual inspection during manufacturing and can be beneficial in applications where color coding is used for part identification.

How does the bar perform in chemical exposure environments?

Delrin acetal exhibits excellent resistance to most oils, greases, and solvents. However, it is not suitable for strong acids or bases. Always verify compatibility with specific chemicals before prolonged exposure.

What warranty does USA SEALING provide for this product?

USA SEALING offers a one‑year limited warranty covering material defects and dimensional inconsistencies. Customers can contact our support team for warranty claims, and we will arrange replacement or repair as appropriate.
