Performance:
1. PU material has high abrasion resistance, high aging resistance, high anti-solvent,
long life span,
2. PU material can protect the belt conveyor effectively. PU conveyor belt scrapers are
used to scrape coal chemical adhesion of ash and powder materials such as coal transportation,
fertilizer delivery, and gravel delivery and so on.
3. PU scraper for scraping cloth products, shaving products, such as the adsorption of water.
4. Our squeegee made of special polyurethane elastomer has the following advantages:
*High abrasion resistance and tear resistance to print high quality materials evenly.
*Excellent resistance and minimum swell to a wide range of pastes and solvents
*Precisely finished edge
*Super solvent resistance
*Long service life
5. Normal Squeegees Mainly used in the glazing line of ceramic, wood and other Industries
with lower polar solvents.
6.Anti-Solvent Squeegees is used in PCB manufacturing enterprises and printing industry.
It’s easy to grind, suitable for printing circuit board.
7. NDI products is super wear-resistant, tear-resistant, super solvent and is suitable to
plastic silk screen.
8. Flat squeegees, squeegees with edge
9. All types could be produced according to your requirement.

Polyurethane is a unique engineering material that offers the elasticity of rubber combined with the toughness and durability of metal. Because polyurethane is available in a very broad hardness range (eraser soft to bowling-ball hard) and various advantages (as below), it can replace rubber, plastic and metal in rollers, sleeve bearings, cushion, anti-pressing and heavy load parts, it is also used in the molding equipment, iron and steel factory, ceramics factory, electronics, oil field, mine, construction and so on.
Advantages of polyurethane product
1. Abrasion resistance
2. Oil and solvent resistance
3. Load bearing capacity
4. Mechanical strength
5. Weather resistance
6. Heat and cold resistance
7. Noise reduction performance
8. Shock absorption performance
9. Electrical insulation properties
