Cast Polyurethane Scrapers
Custom Engineered Scraper Formulations
Most polyurethane scraper blades have a 60A to 90A shore hardness, but PSI Urethanes can engineer scrapers in a range of custom durometers to support your needs. Beyond hardness, PSI can also deliver scrapers that have been customized to withstand unique applications, abrasive surfaces, and harsh chemicals. When you choose PSI, you can trust that you’ll get the most wear out of each product, since each urethane formula is specially made for its application environment.
Urethane generally outperforms rubber, plastic, or metal by a margin of 5 to 1 in severe abrasion and wear applications.

Types of Urethane Scrapers
Conveyor Belt Wipers
Urethane conveyor belt wipers or scrapers are used to keep conveyor belts clean and clear of debris. They can help clear bulky debris like gravel or dirt, or be used to clean and squeegee moisture from belts. Urethane belt wipers last longer than metal, plastic, or steel wiper alternatives.
If needed, conveyor belt wipers can be made using an FDA-approved urethane.
Conveyor belt wipers for pharmaceutical or food processing companies could require food-grade urethane due to the medications coming into contact with them. PSI has several FDA Approved Formulas for such companies to choose from.
Urethane squeegee blades help remove or control the flow of liquid on a flat surface. They’re attached to a tool or core, then pressed into and against a surface to wipe fluid from it, similar to how windshield wipers press and move against your windshield to clear water off of the glass.
Urethane squeegee blades are often used in the cleaning industry on floors and windows, and in screen printing to force ink through a screen and onto the substrate. Many industries prefer urethane squeegee blades over neoprene and rubber blades due to their excellent wear life and exceptional performance in environments where oil or chemicals are present.
Snow Plow Blades
Urethane snow plow blades are specially formulated to withstand the demands of plowing, with exceptional abrasion resistance, low-temperature impact resistance, and a low brittle point. They need to be stiff, but also abrasion-resistant. Urethane snow plow blades are tough enough to do their job but gentle enough to avoid damaging road markings, reflectors, cobblestones, runway lights, and other ground elements.
Urethane snow plow blades are often preferred by hospitals and apartment complexes since this type of blade eliminates the ear-piercing sound of a plow scraping against cement. Urethane blades also don’t need to be replaced as often as rubber or plastic blades and can help reduce truck downtime. In the winter, that’s a win-win for both snow plow operators and residents!
