PU coated gloves

Polyurethane (PU) impregnated gloves are protective gloves coated with polyurethane (PU) coating. 

They are flexible and functional and are widely used in scenarios such as precision operation, 

anti-static, and anti-chemical corrosion. The following is a detailed analysis of PU impregnated rubber gloves and their core values:

First, what is PU coated gloves? 

1. ** Structure and process **

- ** Substrate ** : Usually nylon, polyester or cotton woven gloves as the base, to provide flexibility and permeability.

- ** Coating ** : The palm and fingertip parts are impregnated with polyurethane (PU) material to form a uniform wear-resistant, anti-slip protective layer.

- ** Features ** : PU coating thickness is adjustable (0.3~1.5mm), delicate touch, fit hand curve.

2. ** Key Performance **

- ** Wear resistance ** : PU material has better friction resistance than latex and nitrile, suitable for frequent contact with rough surfaces.

- ** Non-slip ** : Surface micro-texture design, enhance grip strength, prevent tools or precision parts from slipping.

- ** Chemical resistance ** : Some resistance to grease, weak acid/alkali (depending on the coating formulation).

- ** Anti-static function ** (some models) : By adding conductive materials (such as carbon fiber), the surface resistance can be controlled at \(10^6 \sim 10^9 \, \Omega\), suitable for the electronics industry.

Second, why use PU coated gloves?

1. ** Protect sensitive products and operators **

ESD requirements ** : In scenarios such as electronic assembly and chip packaging, conductive particles embedded in PU coatings can deflect static electricity to prevent electrostatic discharge (ESD) damage to components.

Anti-pollution ** : PU coating is compact and dust-free, preventing hand sweat and dander from polluting the dust-free workshop environment (such as semiconductor wafer processing).

Physical Damage protection ** : wear-resistant coatings reduce hand wear while avoiding metal burrs from scratching precision instruments.

2. ** Improve operating accuracy and efficiency **

Sensitive to touch: PU coating is light and soft, and can maintain finger flexibility after wearing, suitable for precision work (such as micro-welding, small parts assembly).

High fit: Elastic substrate + customized dipping process to ensure tight fit of gloves and hands to avoid slipping during operation.

3. ** Adapt to diverse scenarios **

Electronic manufacturing: Anti-static PU gloves are used for circuit board assembly and hard disk production.

Laboratory: Weak acid/alkali resistant PU gloves for chemical reagent packaging.

Automotive maintenance: Wear and oil resistant gloves for mechanical parts disassembly.

Medical field: Powder-free PU gloves are used in medical equipment operation to avoid the risk of latex allergy.

Fourth, how to correctly choose and use PU coated gloves? **

1. ** Select points **

- ** Functional requirements ** :

- Anti-static operation → Select conductive PU gloves with the required surface resistance.

- Chemical contact → Confirm coating resistance (refer to MSDS data).

- ** Size matching ** : Choose the size that fits the hand type, too loose is easy to slip, too tight affects the blood circulation.

- ** Certification Standard ** : Priority is given to products certified by EN 388 (anti-mechanical damage), ANSI/ESD S20.20 (anti-static), etc.

2. ** Use and maintenance **

- ** Check before wearing ** : Ensure that the coating is not damaged or degumming.

- ** Grounding requirements ** (ESD) : Connect to the grounding system of the anti-static station pad through a wrist strap or plug.

- ** Cleaning method ** : Hand wash with neutral detergent, dry to avoid exposure to the sun, no machine washing or drying.

- ** Replacement cycle ** : Replace immediately when there is wear, peeling of coating or deterioration of anti-static performance.

Five, Frequently Asked Questions **

1. **Q: Can PU latex gloves be reused? **

A: It depends on the environment! Lightly worn and not in contact with harmful substances can be reused after cleaning, but the anti-static performance will decrease with the number of cleaning.

2. **Q: What is the difference between PU gloves and PVC gloves? **

A: PVC material is harder, poor air permeability, and poor low temperature resistance (cold brittle); PU is more soft and wear-resistant, better environmental protection.

3. **Q: Why do electronics factories commonly use PU rubber gloves instead of all-rubber gloves? **

A: All-rubber gloves are heavy and have poor touch, affecting precision operation; PU coated gloves provide protection and flexibility, making them more suitable for microelectronics.

Six, summary **

PU impregnated coated gloves through the "flexible substrate + functional coating" design, in the anti-static, anti-slip, wear and other scenarios show unique advantages, especially for the need for high-precision operation and product protection industries. When selecting, it is necessary to clarify the operation requirements (such as whether anti-static and chemical resistance are required), and cooperate with standardized use and maintenance to maximize its protection value.
