UHMW Polyethylene Bar by USA Sealing 12 Inch White Standard Bar

Description

Product Overview

USA Sealing presents a high‑performance UHMW polyethylene bar engineered for demanding industrial and scientific applications. This 12‑inch long, 1/4‑inch thick bar is fabricated from standard‑grade UHMW polymer, offering a dense, opaque white surface that resists abrasion, chemicals, and moisture. The material’s coefficient of friction is exceptionally low at 0.15, making it one of the slipperiest surfaces available, while its hardness of 70D provides a balance of toughness and flexibility. Certified to meet FDA requirements and UL 94 HB flame‑rating standards, the bar can safely contact food products and withstand moderate flame exposure. Its temperature tolerance spans from –70 °F to 180 °F, ensuring reliable performance in both cryogenic and high‑heat environments. With a density of 0.034 lb/cu in, the bar is lightweight yet robust, delivering a tensile strength of 4,400 psi and an impact strength of 16 ft‑lb/in, which translates to excellent resistance to sudden loads. The precise tolerances on thickness (±0.002 in), width (±0.01 in), and length (±1 in) guarantee consistent dimensions for repeatable machining, prototyping, or direct use as wear plates, guides, and protective barriers.

Usage

This UHMW bar excels in a variety of settings where low friction, high impact resistance, and chemical inertness are essential. In manufacturing, it serves as a wear‑resistant liner for conveyor systems, chutes, and hopper guides, reducing material buildup and extending equipment life. Its smooth surface allows products to glide effortlessly, minimizing energy consumption and wear on moving parts. In food processing, the FDA‑compliant material provides a sanitary contact surface for cutting boards, rollers, and transport trays, ensuring compliance with strict hygiene standards. The bar’s excellent water absorption rating (0.0001) prevents swelling or dimensional change when exposed to moisture, making it ideal for wet environments such as washing stations or marine applications. Additionally, its broad temperature range supports use in cryogenic labs for sample handling or in high‑temperature molding processes where the material must retain its shape without degrading. The bar can also be machined into custom shapes, drilled for mounting hardware, or bonded with compatible adhesives for assembly into larger systems.

FAQ

What makes UHMW polyethylene suitable for food‑grade applications?

UHMW polyethylene is chemically inert, non‑porous, and resistant to moisture absorption, which prevents bacterial growth and contamination. The material complies with FDA regulations, meaning it does not leach harmful substances into food products. Its smooth, easy‑to‑clean surface can be sanitized with standard food‑industry cleaning agents, making it a reliable choice for cutting boards, rollers, and transport trays in food processing facilities.

Can the bar be machined or modified to fit custom equipment?

Yes, the UHMW bar can be machined using standard woodworking or plastic‑working tools. It tolerates drilling, routing, and CNC milling without cracking, provided proper cooling and sharp tools are used to avoid heat buildup. The tight dimensional tolerances (±0.002 in thickness, ±0.01 in width) ensure that any modifications retain accurate dimensions, allowing the bar to be integrated into custom fixtures, brackets, or assemblies.

How does the low coefficient of friction benefit industrial systems?

A low coefficient of friction (0.15) means that moving parts experience less resistance when in contact with the UHMW surface. This reduces the energy required to drive conveyors or rollers, lowers wear on both the bar and adjoining components, and minimizes heat generation. In high‑speed applications, the reduced friction can improve throughput and decrease maintenance intervals, delivering cost savings over the life of the equipment.

Is the material resistant to chemicals commonly found in industrial environments?

UHMW polyethylene exhibits excellent resistance to a wide range of chemicals, including acids, bases, solvents, and oils. Its dense molecular structure prevents absorption, so the bar maintains its mechanical properties even when exposed to aggressive substances. This makes it suitable for use in chemical processing plants, pharmaceutical manufacturing, and any setting where contact with harsh chemicals is routine.

What support does USA Sealing provide after purchase?

After purchasing the UHMW bar, customers receive access to a dedicated technical support line staffed by engineers familiar with polymer applications. We provide detailed material data sheets, machining guidelines, and compliance certificates upon request. For bulk orders, we can coordinate just‑in‑time delivery and offer inventory management services to keep your production line running smoothly. Our goal is to ensure you get the most performance out of the product throughout its service life.
