Professional Plastics RPRONA.500X48.000 Polypropylene Rod

Product Description

The PROFESSIONAL PLASTICS RPRONA.500X48.000 is an extruded polypropylene round rod measuring 0.5 inches in diameter and 48 inches in length. Polypropylene is a semi-rigid thermoplastic valued for its chemical resistance, low moisture absorption, and lightweight properties. This rod carries a Rockwell R hardness rating of 90 (HRR), indicating solid rigidity suitable for machined components, jigs, guides, and structural standoffs. At 0.311 pounds per piece, it is easy to handle and cut to length on-site. Trade fabricators, maintenance technicians, and industrial machinists commonly work with this stock material for custom part fabrication.

This polypropylene rod is used across industrial, commercial, and light mechanical fabrication applications. Its natural (uncolored) finish is appropriate where appearance is not a factor and chemical or moisture exposure is a concern. Common applications include fluid-handling components, corrosion-resistant fasteners, bushings, spacers, and custom-machined fittings. The 48-inch length allows for multiple cuts from a single piece, reducing waste in low-volume fabrication work. It is suitable for use in plumbing, chemical processing support structures, and general-purpose shop fabrication.

Key Features

• Extruded polypropylene construction for consistent dimensional stability along the full 48-inch length
• 0.5 inches diameter with a tight tolerance of +0.020 / -0.000 inches for predictable fit in machined assemblies
• Length tolerance of 0.250 inches across the 48-inch stock length
• Rockwell R 90 hardness rating supports use in load-bearing and wear-contact applications
• Natural color polypropylene with low moisture absorption and broad chemical resistance
• Lightweight at 0.311 pounds per piece, reducing material handling effort

Compatibility

Designed as a standard-diameter extruded polypropylene round rod suitable for general industrial fabrication, machining, and replacement part manufacturing where 0.5-inch diameter thermoplastic stock is specified.

Installation Notes

This rod stock is typically cut, drilled, or machined by fabricators using standard woodworking or metal shop equipment with appropriate plastic-cutting blades or bits. Secure the rod firmly in a vise or clamp before cutting to prevent movement and ensure a clean, square cut. Polypropylene generates heat during machining, so use sharp tooling and moderate feed rates to avoid melting or deforming the material. No adhesive bonding is recommended without surface preparation, as polypropylene has low surface energy.
