PU Sponge Roller

PU Sponge Roller Product Description

PU sponge roller is made of Polyurethane sponge, which can instantly absorb water on the surface of the object, while the roller surface is kept dry and transported.

Water cut-off effect, superior water absorption, toughness, high friction resistance can be doubled to extend the service life of the roller,
The roller does not need special water supply, and will not become dry and hard in a water-free state, and always maintains the roundness and elasticity of the roller appearance.

These PU Sponge RollersIt is manufactured by the technology of ultra-fine continuous foam pore size of 5-10 μ. It can instantly absorb the surface water of objects.

At the same time, the roller surface remains dry and has the effect of transport, extrusion, water removal and water cutting, superior water absorption, toughness,high friction resistance can be doubled to extend the service life of the roller, the roller does not need special water supply,it will not dry out in a water-free state, and always maintains the roundness and elasticity of the roller appearance

The PU sponge material is Polyurethane, the pipe material is PVC. We can make hollow PU sponge or PU sponge mounted on PVC pipe.

PU Absorbent Sponge is not easy to mold, more elastic than any other sponge and not easy to tear; PU roller is very light, soft feel good; Compared with conventional sponges, it has superior water absorption, moisture retention and abrasion resistance.

Purpose:

Water absorption: small test, printed circuit board, frame, etc.

Cleaning: computer hard disk, glass, medal, etc.

Smear with: ink roller, various liquid smear.

Liquid cleaning: plating solution, printed circuit board corrosion solution, etc

PU roller

Usage: Absorbing water at for part of drying section after rinsing and washing.

Characteristic: Perfect hydrophobic capacity, 120 temperature resistance, good tenacity, high wear resistance, chemical resistance (CuCl2, HNO3, HCl each 10%).

It can keep wateriness without feeding water and keep soft and in round shape. 5 times as PVA SPONGE service life.

Always soft in both dry and wet condition, high temperature resistance 120 degrees, super absorbent, resistance toacid and alkali, without dust drop off.
It’s widely used on PCB, inner board, IC tripod, gold-plated process, non-embroidered steel plate, LCD display, semiconductor wafer, glass, etc…

The characteristics of PU sponge brush: even in the dry state, it can absorb water instantaneously, and has excellent water retention. And it can adjust the hydrophilicity and lipophilicity. The hardness can be easily adjusted; High mechanical strength, will not fall off from the base; It can be used stably in an environment below 130 ° C; Will not be due to acid, alkali, alcohol deterioration; Because the diameter of the stomata can be freely controlled, the PU Sponge Roller can adjust the ventilation;

PU roller does not need water moisture, Sponge Roller does not dry hard phenomenon, always maintain the roundness and elasticity, increase the service life by 5 times, improve the production speed 6-8M/ min, chemical resistance (copper chloride, nitric acid, hydrochloric acid) made of polyethylene with chemical resistance sponge water pipe. Does not harden, temperature resistance 60℃, good water absorption, excellent water retention, chemical resistance, do not need water moisture.

Physical Feature

Suitable for:chemical liquid resistance in etching section and water absorption roller after washing. (Automatic developing machine, developing liquid, fixed liquid washing water suction)

Features: not dry and hard, temperature resistance 60℃, good water absorption, excellent water retention, chemical resistance (sulfuric acid, hydrochloric acid 30%, phosphoric acid, sodium hydroxide, ammonium water 10%).

PU roller feature:

4. Tolerate to higher working temperature.

PU sponge is an abrasive resistance sponge roller that suits for more demanding working environment.

PU sponge roller is suitable for: PCB equipment after washing, drying the front section, drying the front section of water absorption pipe after the air knife.

Features: not hard and dry, temperature resistance 120℃, good water absorption, good toughness, friction resistance, no chips.

About Maintaince:
1.After use, pour tap water into the PU sponge roller on the machine, and then squeeze the dirt on the roll by hand
2.The roller does not need special water supply, will not dry and hard in the state of no water, and will always be soft to maintain the roundness and elasticity of the shape

1. Water absorption: Sponges can absorb a lot of water because their porous structure can accommodate water into them. This makes sponges very useful for cleaning, wiping and absorbing liquids.

   2. Flexibility: PU roller sponge materials are usually very soft and can be bent, folded and cut as needed. This allows sponges to be used in furniture and software products such as mattresses, cushions and throw pillows.

   3. Elasticity: Although sponge is soft, it also has a certain elasticity and can return to its original shape. This makes the sponge have good cushioning and shock absorption effect, which can be used to make sports shoes, car seats and other products that need to reduce impact.

   4. Permeability: Due to its porous structure, sponges have good permeability and can promote air circulation. This makes sponges potentially useful in the production of ventilation materials, filters and sound insulation materials.

   5. Durability: PU roller materials usually have a long service life and can withstand repeated use and cleaning. This makes sponges an affordable and environmentally friendly option that can reduce the need for disposable products.
