UHMW Polyethylene Bar USA Sealing 12x2x0.125in White FDA UL94HB

Description

Product Overview

USA Sealing presents a high‑performance UHMW polyethylene bar engineered for demanding environments where durability, low friction, and chemical resistance are essential. Ultra‑High‑Molecular‑Weight (UHMW) polyethylene is renowned for its exceptional impact strength, wear resistance, and self‑lubricating properties, making it a preferred material in a wide range of industrial and commercial applications.

Each bar measures 12 inches in length, 2 inches in width, and 1/8 inch (0.125 in) in thickness, with tight dimensional tolerances of ±0.01 inches on width and ±0.003 inches on thickness, and a length tolerance of ±1 inch. The white, opaque finish provides a clean, uniform appearance that integrates seamlessly into assemblies where aesthetics and consistency matter. The material’s hardness of 70D and density of 0.034 lbs/cu in. contribute to a lightweight yet robust component that can be easily machined, cut, or fabricated to meet custom specifications.

Designed to meet stringent industry standards, this bar complies with FDA regulations for food‑contact safety and UL 94 HB flame‑retardancy classification. It operates reliably across a broad temperature spectrum from –70 °F to 180 °F, ensuring performance stability in both cryogenic and high‑heat environments. The coefficient of friction is measured at 0.15, delivering a very slippery surface that reduces wear on mating parts and minimizes energy consumption in moving systems.

Manufactured by USA Sealing Inc., a trusted name in sealing solutions, the product is sourced from a controlled production line that emphasizes consistency and quality. The bar is packaged in bulk quantities to support large‑scale projects while maintaining protection against moisture and contamination. With a best‑seller rank in the Plastic Bars category, it has earned a reputation for reliability among engineers, fabricators, and maintenance professionals.

Key technical specifications include a tensile strength of 4,400 psi (rated as poor for tensile load but compensated by superior impact resistance), an impact strength of 16 ft‑lb/in (rated excellent), and water absorption of only 0.0001 % (excellent). These attributes collectively ensure that the bar performs reliably under cyclic loading, abrasive contact, and exposure to fluids without degradation.

Whether you require a component for prototype development, production tooling, or replacement parts, this UHMW polyethylene bar offers a versatile platform that can be integrated into a multitude of designs. Its compatibility with FDA‑approved processes makes it suitable for food processing equipment, while its flame‑retardant rating supports safety‑critical applications in manufacturing facilities.

Usage

The UHMW polyethylene bar excels in applications where low friction and high impact resistance are paramount. It is commonly employed as a wear strip in conveyor systems, a sliding surface for guide rails, and a protective barrier in material handling equipment. Its chemical inertness allows it to be used in environments exposed to solvents, acids, and oils without compromising structural integrity.

In food‑processing plants, the bar’s FDA compliance and non‑porous surface make it an ideal choice for conveyor rollers, chute liners, and cutting board inserts where hygiene and easy cleaning are critical. The material’s resistance to bacterial growth and its ability to withstand repeated sanitation cycles extend the service life of equipment while reducing downtime.</n

For DIY enthusiasts and small‑scale fabricators, the bar can be cut to custom lengths, drilled for mounting, or machined into complex shapes, providing a flexible material for hobby projects, prototype fixtures, and custom tooling. Its lightweight nature simplifies handling and installation, while its durability ensures long‑term performance even in high‑stress scenarios.

Industrial users also benefit from the bar’s temperature tolerance, employing it in cold‑chain logistics for insulating components or in high‑temperature molding processes where thermal stability is required. The low coefficient of friction reduces wear on adjacent metal parts, extending the lifespan of both the UHMW component and the mating hardware.

FAQ

What does UHMW stand for and why is it beneficial?

UHMW stands for Ultra‑High‑Molecular‑Weight polyethylene. It offers superior impact strength, excellent wear resistance, and a self‑lubricating surface, making it ideal for high‑stress, low‑friction applications.

Is this bar suitable for food‑processing equipment?

Yes. The bar meets FDA food‑contact standards and is designed to resist bacterial growth, making it safe for use in conveyors, chutes, and cutting surfaces within food‑processing facilities.

Can the bar be machined or cut to custom dimensions?

Absolutely. UHMW polyethylene can be easily cut, drilled, and machined with standard tools. Its dimensional tolerances ensure accurate sizing for custom projects.

What does the UL94HB rating indicate?

UL94HB is a flame‑retardancy classification indicating that the material has a horizontal burn rating. It means the bar will self‑extinguish after the flame source is removed, enhancing safety in industrial settings.

How does the low water absorption benefit my application?

With a water absorption rate of only 0.0001%, the bar remains stable and retains its mechanical properties even when exposed to moisture, preventing swelling or loss of strength.
