High-Quality Polyurethane Sheets from China - Reliable Suppliers and Factory for Durable Products
Our company supply various of Polyurethane plates, also can mold and design related goods according to your request, except Polyurethane plates, we also have Polyurethane conveyor belt scraper, flotation machines rotor, Polyurethane shaft, and hydro cyclone.
Polyurethane has the advantages of high hardness, good strength, high elasticity, high abrasion resistance, tear resistance, aging resistance, ozone resistance, radiation resistance and good electrical conductivity.
Products Features
(1) Superior Wear Resistance
The highest wear resistance among all rubbers. Laboratory measurement results show that the polyurethane abrasion resistance is 3 to 5 times of natural rubber, and it is often 10 times high in actual applications.
(2) High Strength & Elasticity
High strength and good elasticity within Shore A60 and Shore A70 hardness range.
(3) Cushioning & Shock Absorption
Good cushioning and shock absorption. The shock-absorbing element can absorb 10%~20% of the vibration energy at room temperature. The higher vibration frequency, and greater the energy absorption.
(4) Oil & Chemical Resistance
Good oil resistance and chemical resistance. Polyurethane products have low affinity with non-polar mineral oils, and are hardly corroded in fuel oils (such as kerosene, gasoline) and mechanical oils (such as hydraulic oil, engine oil, lubricating oil, etc.), and are much better than general rubber, Comparable to nitrile. The disadvantage of it is having greater swelling in alcohols, esters, ketones and aromatic hydrocarbons.
(5) Friction Coefficient
The friction coefficient is relatively high, generally above 0.5.
(6) Environmental Resistance
Low temperature resistance, ozone resistance, electrical insulation, and good bonding performance.
PU Polyurethane Belt Cleaner Conveyor Belt Scraper
Hesper can offers a wide range different types of primary, secondary and tertiary conveyor belt cleaners scraper. Cleaner scraper be designed to keep the conveyor belt, pulleys and rollers as clean as possible, thus prolonging service life, improving belt tracking, minimizing spillage, raising performance and improving safety and economy, they are quality, compact and efficient design and easy to maintain, can be Installed on the head pulley to provide effective cleaning.

Frequently Asked Questions (FAQ)
What kinds of Polyurethane products do you supply?
We supply various Polyurethane plates, and we can also mold and design related goods according to your request. In addition to plates, our product range includes Polyurethane conveyor belt scrapers, flotation machine rotors, Polyurethane shafts, and hydro cyclones.
What are the primary advantages of Polyurethane material?
Polyurethane offers multiple advantages, including high hardness, good strength, high elasticity, superior abrasion resistance, tear resistance, aging resistance, ozone resistance, radiation resistance, and good electrical conductivity.
How does Polyurethane's wear resistance compare to natural rubber?
Polyurethane features the highest wear resistance among all rubbers. Laboratory measurements show its abrasion resistance is 3 to 5 times that of natural rubber, and it often performs up to 10 times better in actual field applications.
Is Polyurethane resistant to oils and chemicals?
Yes, Polyurethane has excellent resistance to non-polar mineral oils, fuel oils (like gasoline and kerosene), and mechanical oils (like hydraulic, engine, and lubricating oils). However, it may experience swelling when exposed to alcohols, esters, ketones, and aromatic hydrocarbons.
Why are conveyor belt scrapers necessary?
Conveyor belt scrapers are designed to keep the conveyor belt, rollers, and pulleys as clean as possible. This helps prolong the service life of the equipment, improves belt tracking, minimizes material spillage, and increases overall operational safety and economic efficiency.
