1. Polyurethane rollers are with high strength, compressive strength, abrasion resistance, oil resistance, corrosion resistance and bonding firmly without degumming. They are widely used in metallurgy, paper, coal, wood processing, chemical fiber, textile, printing and other industries.
2. Roller and PU Coating:
(1)Metallurgy Roller: Due to cost considerations, CPU roller, mainly used in poor working conditions, high quality requirements occasion, such as the pinch roller, tension roller, pressure roller, transfer roller, guide roller etc, for example cold roller is belong to hard rubber roller, hardness: Shore A 90 ± 5, tensile strength> 40MPa, elongation> 400%, Akron < 0.08cm 3 / 1.61KM and the peel strength steel shaft> 500KN / m, the tension roller larger size φ 1.5 ~ 1.7m, Long 1.7m- 2m, Thick plastic 20mm. They are requiring high strength, compression deformation, and wear resistance. Color thin roller is used for painting stainless steel, in addition to wear resistance, it also require corrosion resistance and good elasticity, so as to keep the printing even and beautiful. (Normal hardness is shore A 40 ~ 60)
(2)Printing rollers: Including letterpress printing roller (Shore A20 ~ 30), offset printing rubber roller (Shore A38 ~ 45) and high-speed printing rollers etc., due to CPU low hardness, high strength, elasticity, wear resistance and greaseproof printing ink, it is very suitable for low hardness, high-speed printing rollers.
(3) Rubber roller for hulling rice: The CPU instead of ordinary rubber roller can increase the service life of 3 to 4 times without contaminating food.
(4)Paper Roller: Its production efficiency can be increased by 1 time or more, and reduce energy consumption and costs.
(5)Textile Roller: Used to pelletizing roller, drawing roller, drafting roller can extend service life.
3. PU Wheel:
The CPU's load capacity, wear resistance, high strength can be used for heavy solid load wheel, such as battery car, auto-lift trucks, mining trucks and forklifts solid wheel. It is also suitable for various cable wheel, roller, textile speed wheel (n = 50 ~ 40 million rpm), mall elevator wheel and precision equipment miniature wheels etc.
4. Applications:
Used to PU roller, printing roller, UV roller, rotary machine, adhesive roller, roller coating machine, manual removal wheel, mechanical dedust roller, industrial casters, hot press rollers, trademark machine roller, rubber tire, PU wheel, paper pressing wheel, rubber and plastic truck wheel for printing, electronic, textiles, wood, plastic, machinery. Folding machine roller, roller coating machine, stripping wheel, granulator rubber roller, conveyor roller, glue roller, self-adhesive roller, sticky roller, rotary roller, pressure roller. Mill Valley Cots, printing, dyeing, iron printing, metallurgy, textile and other industries used rubber roller and special-purpose silicone roller, polyurethane rubber roller, precision machinery supporting roller etc.
1 |
Hardness: shore A 10- Shore D 85 |
2 |
High strength Under rubber hardness, its strength and loading capacity is much better than rubber. Under high hardness, its impact resistance and flexibility are much better than plastic. |
3 |
Excellent anti-abrasion performance it is about 3-5 times of rubber. |
4 |
Oil resistance Polyurethane is a strong polar polymer compound.Its affinity with non-polar oil is very slim, so there is almost no erosion in fuel oil and mechanical oil. |
5 |
Superior anti-aging properties, good resistance to oxygen and ozone
|
6 |
PU Roller is with good physical properties, it won't harden or age under long term usage, and it maintains good tear resistance, resilience and anti-abrasion performance. It is easy to store for a long time. Its anti-abrasion performance is 3-5 times of rubber. Its life span is more than 3 times compared with rubber roller. |
7 |
It is with excellent mechanical reprocessing properties. |
8 |
The metal part strongly bonds with PU. It won't break out. It could also be oil resistance, water-proof or anti-solvent |
