1. Text: 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. 1Hardness: shore A 10- Shore D 85 2High 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. 3Excellent
anti-abrasion performance it is about 3-5 times of
rubber.4Oil 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.5Superior
anti-aging properties, good resistance to oxygen and ozone 6PU
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. 7It is with excellent mechanical reprocessing
properties. 8The metal part strongly bonds with PU. It won't
break out. It could also be oil resistance, water-proof or
anti-solventFactory Show: /* January 22, 2024 19:08:37
