UHMW Polyethylene Bar by USA Sealing – 48 x 4 Inch Black Standard

Description

Product Overview

The USA Sealing UHMW polyethylene bar is a 48‑inch long, 4‑inch wide, 1‑inch thick standard‑grade plastic bar designed for industrial and scientific use. Crafted from high‑density UHMW polymer, it offers a hardness of 70D, a tensile strength of 4,400 psi, and an impact strength of 16 ft‑lb/in, making it exceptionally resistant to wear and shock. Its very slippery surface (coefficient of friction 0.15) reduces drag in material handling applications, while the near‑zero water absorption (0.0001) ensures dimensional stability in wet environments. Certified to meet FDA and UL 94 HB standards, this black, opaque bar is suitable for food‑contact and chemical‑resistant applications.

Usage

Ideal for conveyor guides, wear strips, chute liners, and equipment protection, this bar performs reliably in temperatures ranging from -70°F to 180°F. Its low friction makes it perfect for sliding surfaces in manufacturing plants, while the high impact rating protects machinery from sudden shocks. Engineers, fabricators, and maintenance teams appreciate its easy machining and consistent tolerances, allowing quick installation in custom fixtures.

FAQ

What is the recommended machining method for this UHMW bar?

Standard CNC milling or drilling with sharp carbide bits works well; avoid excessive heat to maintain material integrity.

Can this bar be used in food processing equipment?

Yes, it meets FDA requirements for food‑contact applications, making it suitable for conveyors and slicers.

How does the low friction coefficient benefit my operation?

The 0.15 coefficient reduces drag, allowing smoother movement of parts and decreasing energy consumption.

Is the bar resistant to chemicals?

UHMW polyethylene offers excellent resistance to most acids, bases, and solvents, suitable for harsh chemical environments.

What is the warranty on this product?

USA Sealing provides a one‑year limited warranty covering material defects and dimensional inconsistencies.
