Description
Product Overview
The USA Sealing UHMW plastic bar is engineered from ultra‑high‑molecular‑weight polyethylene, a material celebrated for its exceptional wear resistance, low coefficient of friction, and outstanding impact strength. Measuring 0.25 inches in thickness, 1.25 inches in width, and a full 24 inches in length, this white bar delivers a versatile size that fits a broad range of industrial applications, from material handling components to custom‑fabricated parts. The bar’s density of 0.034 lbs per cubic inch translates to a lightweight yet robust profile, allowing easy handling while maintaining structural integrity under demanding loads.
Manufactured by USA Sealing Inc., a reputable supplier in the raw materials sector, the product meets stringent standards including FDA approval for food‑contact safety and UL 94 HB flame‑retardant classification. Its hardness rating of 70D ensures a surface that resists scratches and abrasions, while the coefficient of friction of 0.15 provides a very slippery surface ideal for applications requiring smooth movement, such as conveyor rollers, guide rails, and bearing surfaces.
Temperature resilience is another hallmark of this UHMW bar. It operates reliably from -70°F to 180°F, making it suitable for both cryogenic environments and high‑temperature processes without degradation of mechanical properties. Water absorption is virtually negligible at 0.0001, guaranteeing dimensional stability even in humid or wet conditions, a critical factor for marine, chemical processing, and outdoor equipment.
Beyond its physical attributes, the bar’s chemical resistance is noteworthy. UHMW polyethylene resists a wide spectrum of chemicals, including acids, bases, and solvents, allowing the bar to be employed in aggressive environments where other plastics might fail. This chemical inertness, combined with its impact strength of 16 ft‑lb/in, positions the product as a reliable solution for protective pads, impact buffers, and shock‑absorbing components.
In addition to its functional performance, the bar’s opaque white coloration provides a neutral aesthetic that can blend seamlessly into a variety of settings, from cleanroom facilities to heavy‑duty manufacturing floors. The plain backing type ensures that the bar can be easily machined, drilled, or cut to precise dimensions, supporting custom fabrication needs without the complications of additional coatings or laminates.
Overall, the USA Sealing UHMW plastic bar represents a balance of durability, versatility, and compliance, delivering a product that meets the rigorous demands of modern industrial applications while offering ease of use and adaptability for engineers and fabricators.
Usage
In industrial settings, the UHMW bar excels as a component in material handling systems. Its low friction surface reduces wear on moving parts, extending the lifespan of rollers, chutes, and conveyor belts. The bar can be installed as a wear strip on high‑impact zones, protecting more expensive equipment from abrasion and deformation.
Food processing facilities benefit from the bar’s FDA‑approved status, allowing it to be used in slicers, mixers, and conveyor components that come into direct contact with consumable products. The non‑porous nature of UHMW prevents bacterial growth, supporting stringent hygiene standards required in the food industry.
Marine and offshore applications leverage the bar’s resistance to saltwater corrosion and its negligible water absorption. It serves effectively as a protective liner for boat hulls, dock fenders, and underwater equipment housings, where durability and low maintenance are paramount.
In chemical plants, the bar’s chemical inertness makes it an ideal choice for guide rails, pump housings, and valve components that encounter aggressive solvents or acids. Its ability to maintain mechanical properties under chemical exposure reduces the need for frequent replacements, lowering operational costs.
Custom fabrication shops often require a material that can be easily machined to precise tolerances. The plain backing type of this UHMW bar allows for CNC machining, drilling, and laser cutting without the risk of delamination or surface damage, enabling the creation of bespoke parts for specialized equipment.
Outdoor equipment, such as agricultural machinery and construction tools, can incorporate the UHMW bar as a protective edge or sliding surface. Its resistance to temperature extremes ensures reliable performance from freezing winter mornings to scorching summer afternoons.
Overall, the bar’s versatility across sectors—from manufacturing and food processing to marine and chemical environments—makes it a go‑to solution for engineers seeking a high‑performance, low‑maintenance material.
