Usa Industrials BULK-PS-ACB-1105 Acetal Plastic Bar

Product Description

The USA INDUSTRIALS BULK-PS-ACB-1105 is a black acetal (POM) plastic bar stock used in precision machining, fabrication, and industrial applications. Measuring 0.75 inches thick and 48 inches long with a square cross-section, this bar is produced porosity-free, making it suitable for parts that require consistent density and machinability throughout. Acetal is a rigid, low-friction engineering thermoplastic commonly used to produce bushings, wear pads, gears, rollers, and structural components. Licensed machinists, millwrights, and industrial fabricators typically work with this material when metal alternatives would add unnecessary weight or introduce corrosion concerns.

This acetal bar stock is suited for use in light industrial, OEM manufacturing, and MRO applications where dimensional stability and low moisture absorption are required. Typical use cases include cutting blanks for custom parts, guide rails, slide components, and fluid-handling components where a porosity-free material is critical to prevent leakage or contamination. The black color is uniform throughout, so finished machined parts retain consistent appearance after cutting.

Key Features

• Porosity-free construction ensures consistent density for precision machined parts
• Acetal (POM) material offers high rigidity, low friction, and good dimensional stability
• Square cross-section at 0.75 inches thick simplifies setup for milling and turning operations
• 48 inches length provides a full 4-foot blank for single or multiple part cutoffs
• Black colorant is uniform through the full cross-section
• Low moisture absorption makes this suitable for wet or fluid-adjacent environments

Compatibility

Designed as a general-purpose acetal bar stock for use in CNC machining, manual milling, lathe turning, and fabrication operations across industrial and OEM production environments.

Installation Notes

Cutting and machining of acetal bar stock should be performed with appropriate tooling for engineering thermoplastics, including sharp carbide or HSS tooling to prevent melting or burring. Standard shop safety practices apply, including eye protection and adequate chip evacuation. Acetal dust and chips are combustible, so keep work areas clear of open flame and follow applicable shop ventilation guidelines. Always measure and mark cut lines carefully before sawing, as finished bar length cannot be extended after cutting.
