USA Sealing Black UHMW Polyethylene Plastic Bar, 1/4″ Height, 1-1/2″ Width, 48″ Length

Description

Product Overview

The USA Sealing black UHMW polyethylene bar is engineered for demanding industrial environments where durability, low friction, and chemical resistance are essential. Constructed from standard‑grade UHMW polyethylene, the bar measures 1/4 inch in thickness, 1‑1/2 inches in width, and 48 inches in length, delivering a solid, opaque profile that resists wear, impact, and moisture absorption. Its hardness of 70D and tensile strength of 4,400 psi provide a robust material that can withstand heavy loads while maintaining dimensional stability across a temperature range of –70 °F to 180 °F. The bar meets FDA and UL 94 HB specifications, making it suitable for food‑grade applications and fire‑safety requirements.

Usage

This versatile bar is ideal for a wide variety of applications. Use it as a wear plate on conveyor rollers, a low‑friction guide in material handling systems, or a sealing component in chemical processing equipment. Its excellent impact strength (16 ft‑lb/in) and very slippery surface (coefficient of friction 0.15) reduce wear on moving parts and extend equipment life. The bar’s low water absorption (0.0001) ensures performance in wet or humid conditions, while its FDA compliance allows safe contact with food products. Whether you need a replacement part for a packaging line, a custom fixture for a laboratory setup, or a durable component for a marine environment, this UHMW bar delivers reliable performance.

FAQ

What does UHMW stand for and why is it beneficial?

UHMW stands for Ultra‑High‑Molecular‑Weight polyethylene. It offers superior abrasion resistance, low friction, and high impact strength, making it ideal for wear plates, guides, and sealing applications where durability is critical.

Can this bar be used in food‑processing equipment?

Yes. The bar meets FDA specifications, meaning it is safe for direct contact with food products and can be used in sanitary processing lines.

What temperature range can the material tolerate?

The UHMW polyethylene bar performs reliably from –70 °F up to 180 °F, allowing use in both cold storage and high‑heat industrial processes.

Is the bar available in other colors or sizes?

Currently, this model is supplied in black with the dimensions 1/4″ × 1‑1/2″ × 48″. Contact USA Sealing for custom color or size options to match specific project requirements.

How do I install the bar safely?

Secure the bar using appropriate fasteners or brackets that match the 1‑1/2″ width. Ensure the mounting surface is clean and level to avoid stress concentrations. For high‑load applications, consider using additional support brackets at intervals no greater than 12 inches.
