Pure Nitrile gloves are made of Nitrile Rubber using a dip molding process and contain no natural latex at all. Because of their excellent performance, nitrile gloves are widely used in medical, laboratory, industrial, and daily life fields. What are pure nitrile gloves?
1. Nitrile Glove Production Process
In general, pure nitrile gloves are made by the following methods.
A ceramic or metal hand mold is first dipped into a nitrile rubber solution to form a uniform coating of nitrile. The rubber is then cross-linked by heating vulcanization to increase strength and elasticity. The surface is then cleaned to remove residual chemicals, dried, and chlorinated. Finally, the finished gloves are formed for quality inspection and packaging and are ready for delivery.
2. Nitrile Glove Material
Pure nitrile gloves are mainly made of nitrile rubber.
Pure nitrile gloves are characterized by the absence of natural latex and will not cause allergies. In addition, the acrylonitrile content of nitrile gloves is high, so the chemical resistance is strong, but the glove elasticity may be reduced.
3. Advantages of Nitrile Gloves
Pure nitrile gloves offer the following significant benefits:
Good chemical resistance. Nitrile gloves have good protection against oils, acids, and chemical solvents, so they can be used in industries such as automobile manufacturing and maintenance, laboratories, or hair salons.
Good puncture resistance. Pure nitrile gloves are more resistant to tear and puncture than latex and PVC gloves.
Good elasticity and fit. Provides excellent hand fit for fine handling.
Hypoallergenicity. No latex protein, suitable for sensitive people.
Anti-static performance. Suitable for the environment requiring anti-static electricity, such as the electronics industry.
4. Nitrile Gloves Application
Due to their material properties, nitrile gloves are often used in a wide range of life and production fields.
Medical industry: Surgery, examination, dentistry, and other scenarios. Doctors often wear nitrile gloves to touch the patient’s position, which avoids the cross-transmission of bacteria, which is widely used in the medical field.
Laboratory: Workers are exposed to chemicals, biological samples, etc. They wear nitrile gloves to protect their skin from chemical damage.
Industrial field: Automobile maintenance, mechanical processing, chemical operation, etc. Nitrile gloves prevent oil from touching the skin, and their anti-puncture function protects the hands from scratches.
Food processing: Handling food ingredients, cleaning equipment, etc. Nitrile gloves prevent bacteria from coming into contact with food, thus meeting the required food hygiene standards.
Daily use: Cleaning, gardening, and other domestic scenes. Note that nitrile gloves are disposable products and should not be used too many times, otherwise, they will lose their original performance.
5. Nitrile Glove Color
Pure nitrile gloves come in a variety of colors.
Blue: The most common color, easy to identify damage.
Black: Often used in industrial fields, dirty and not easy to show dirt.
Purple: Usually high specification gloves, used in special scenarios.
White: Mostly used in medical and laboratory settings, it appears clean and hygienic.
6. Nitrile Glove Thickness
The thickness of pure nitrile gloves varies according to the application:
Thin (0.05-0.08mm): Suitable for delicate operations, such as medical examinations and laboratory work.
Medium (0.08-0.12mm): Flexibility and protection, suitable for general industrial use.
Thick type (0.12mm or more): Provides stronger protection and is suitable for heavy industry or high-risk environments.
7. Powder Free Design
Powder-free gloves: Modern pure nitrile gloves are mostly powder-free, and the surface is chlorinated or coated to make it smoother to wear, avoiding allergies or pollution caused by powder.
Powder gloves: Early gloves would add cornstarch or talc powder to make them easy to wear, but the powder may cause skin irritation or pollute the environment and has been gradually phased out.
8. Sterilization and Non-sterilization
Sterilized gloves: Sterilized with ethylene oxide or gamma rays for use in sterile environments such as operating rooms or sterile laboratories. Packages are usually marked “Sterile”.
Non-sterile gloves: Not sterilized, suitable for general protection scenarios, such as cleaning, food processing, etc.
