High-Quality Polyurethane Sheets and Products from China Suppliers and Factory - Durable and Versatile Solutions
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
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 and good elasticity within Shore A60 and Shore A70 hardness range.
3
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
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
The friction coefficient is relatively high, generally above 0.5.
6
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
What types of polyurethane products does your company supply?
We supply various Polyurethane plates, Polyurethane conveyor belt scrapers, flotation machine rotors, Polyurethane shafts, and hydro cyclones. We can also mold and design related goods according to your requests.
What are the primary performance advantages of polyurethane?
Polyurethane is characterized by high hardness, excellent strength, high elasticity, high abrasion resistance, tear resistance, aging resistance, ozone resistance, radiation resistance, and good electrical conductivity.
How does the wear resistance of polyurethane compare to natural rubber?
Polyurethane has the highest wear resistance among all rubbers. Laboratory measurements show that polyurethane's abrasion resistance is 3 to 5 times that of natural rubber, and it is often up to 10 times higher in actual applications.
Does polyurethane have good chemical and oil resistance?
Yes. Polyurethane products have a low affinity with non-polar mineral oils and are highly resistant to corrosion in fuel oils (such as kerosene, gasoline) and mechanical oils (such as hydraulic oil, engine oil, and lubricating oil). However, it experiences greater swelling in alcohols, esters, ketones, and aromatic hydrocarbons.
What are the benefits of using PU conveyor belt cleaner scrapers?
Our primary, secondary, and tertiary conveyor belt scrapers are designed to keep the conveyor belt, pulleys, and rollers as clean as possible. This prolongs service life, improves belt tracking, minimizes spillage, raises performance, and improves safety and operation economy.
