Market Situation
In 2021, the market for nitrile gloves has two extremes. One is suitable for extremely demanding industries such as HDD, and the price of this kind of nitrile gloves is naturally high. The other is mainly domestic nitrile gloves. Due to the influence of raw materials and production technology, this type of nitrile gloves is of low quality and low price, and is mainly used in industries with low-end requirements.
The status quo of the nitrile gloves market has led to two extremes when customers choose: one is to use ultra-high-quality nitrile gloves, but they have to bear the heavy cost of consumables. The other is to use extremely inexpensive nitrile gloves, but at the cost of a higher rate of defective products.
Latex Gloves
Latex gloves are a kind of gloves, which are different from ordinary gloves and are made of latex. It can be used as household, industrial, medical, beauty and other industries, and is an essential hand protection product. The latex gloves are made of natural latex and other fine auxiliaries. The products are specially surface-treated and comfortable to wear. They are widely used in industrial and agricultural production, medical treatment and daily life.

Process Brief
The rubber is first sliced by a rubber mixer, and then sent to a sol tank to mix the sol with gasoline. The sol is then emulsified and modulated and then pumped to the latex intermediate tank. The rubber solution dissolved in gasoline is fed from the top of the distillation tower, heated and distilled by steam, the light component gasoline is heated into a gas phase, and the gasoline gas is mixed with cold water in the oil and gas cooler and cooled. The oil-water mixture is then sent to the oil-water separator, and the oil-water layer is separated. The upper layer gasoline is recovered, and the lower water is pumped to the cooling water tower for cooling, and then the gas gasoline in the distillation tower is cooled after cooling; the latex in the distillation tower kettle is sent to the latex mixing tank to be stirred according to its own pressure, and after modulation, the glove raw material latex is separated from the centrifuge. After toning and filtering, it is ready for use.
The glove model is first cleaned with acid and alkali and washed with water. The cleaned model is first immersed in hot water and heated, then dipped in coagulant and dried for dipping. After dipping, it is sent to the oven for preliminary drying, the fiber inner sleeve is added, and the hot water is sent to the oven for vulcanization, drying and molding. After the gloves are demolded, they are inflated for inspection, shaped at low temperature, dried at medium temperature, washed with water, dehydrated, dried, and then packaged and sent to the finished product warehouse.
Features
Latex gloves are suitable for automobile manufacturing, battery manufacturing; glass fiber reinforced plastic industry, aircraft assembly; aerospace field; environmental cleaning and cleaning. Latex gloves have abrasion resistance, puncture resistance; acid and alkali resistance, grease, fuel and various solvents, etc.; have a wide range of chemical resistance, good oil resistance; FDA certification. The characteristics of latex gloves include a unique fingertip texture design, which greatly enhances the grip and effectively prevents slipping; no palm pattern patent design, uniform glue penetration, and enhanced protection; unique hand design, cotton lining, improve comfort.
Classification standard of latex gloves
Latex gloves are divided into five types: smooth latex gloves, hemp latex gloves, striped latex gloves, transparent latex gloves and powder-free latex gloves. Latex gloves are divided into: disposable latex gloves, household latex gloves, industrial latex gloves, Medical latex gloves, etc; It is different from ordinary gloves and is made of latex. It can be used in household, industrial, medical, beauty and other industries, and is an essential hand protection product. The latex gloves are made of natural latex and other fine auxiliaries. The products are specially surface-treated and comfortable to wear. They are widely used in industrial and agricultural production, medical treatment and daily life.
The difference between latex gloves and nitrile gloves
1. Material difference
Latex gloves are also called rubber gloves. Latex is a natural material, derived from the sap of rubber trees. Natural latex is a biosynthetic product. Due to different tree species, geology, climate and other related conditions, its composition and structure often vary greatly. In the fresh latex without adding any substances, rubber hydrocarbons only account for 20%-40% of the total, and the remaining small amounts are non-rubber components and water. The non-rubber components include proteins, lipids, carbohydrates and inorganic components, and some of them form a composite structure with rubber particles, and some are dissolved in whey or form non-rubber particles.
Nitrile is a kind of rubber, mainly synthesized from acrylonitrile and butadiene, and is a key material for organic synthesis and pharmaceutical intermediates.
2. Classification difference
The latex gloves are divided into powder ordinary type and powder-free purification type, with smooth surface and hemp surface anti-skid.
The nitrile glove model is divided into palm hemp surface non-slip and hand tip hemp surface non-slip, overall hemp surface non-slip, generally powder-free.
3. Hypoallergenic
Latex gloves contain protein, which is prone to allergic reactions for people who are prone to allergies.
Nitrile gloves do not contain proteins, amino compounds and other harmful substances, and are rarely allergic.
4. Degradability
Both latex gloves and nitrile gloves are degradable, easy to handle, and environmentally friendly.
5. Puncture resistance
The toughness and abrasion resistance of latex gloves are slightly inferior to nitrile gloves.
The puncture resistance of nitrile gloves is three to five times higher than that of latex. For dentists who need to use sharp tools, durable nitrile gloves can create a safer barrier in contact with patients.
6. Elasticity
Latex gloves are soft and wear-resistant, and their elasticity is better than nitrile gloves.
7. Fit the hand shape
Because nitrile gloves contain butadiene monomer, which enables them to be a flexible rubber, it allows the wearer to experience optimal tactile sensitivity. Additionally, the fit is due to its good thermal conductivity, a property that provides excellent flexibility, which is especially important for medical professionals or those working with small parts or tools.
8. Price
Because the chemical resistance and acid and alkali resistance of nitrile material are much better than that of latex, the price of nitrile gloves is higher than that of latex products.
9. Color
The nitrile material can be added with pigments, and the color is brighter. It can relieve the tension of the patient.
In addition, nitrile gloves have certain antistatic properties because of their silicon-free composition, low surface chemical residues, low ion content, and small particle content, making them suitable for strict clean room environments.
To sum up, there is no absolute good or bad gloves, and people can choose the gloves that suit their needs according to their needs.
When wearing nitrile gloves, pay attention to:
1. Do not wear rings or other jewelry on your hands;
2. The fingernails should be trimmed regularly, not too long, so as not to cause damage to the fingertips of the gloves;
3. Prevent the puncture of sharp objects, such as needles, toothpicks, etc.;
4. When taking off the gloves, it is necessary to slowly withdraw from the wrist, and cannot be pulled from the fingers;
5. Pay attention to the size when choosing, too small will cause the blood to flow unsmoothly, and too large will easily fall off;
6. Regular inspections are required, if any damage is found, it cannot be used again.
The precautions for latex gloves are as follows:
1. Avoid contact with chemicals such as acids, bases, and organic solvents.
2. When dealing with infectious substances, powder-free and low-protein latex gloves should be selected. Powder-free and low-protein latex gloves can reduce the risk of allergies. However, the so-called hypoallergenic latex gloves cannot reduce the risk of latex allergy, but can only reduce allergic reactions caused by chemical additives in latex gloves.
3. Resolutely implement the work code to reduce the chance of latex harm. Such as:
1) Do not use oily hand ointment or lotion when wearing latex gloves, which will cause the latex gloves to decline or be damaged.
2) After taking off or removing latex gloves, wash hands with mild soap and dry hands completely.
3) Disposable latex gloves cannot be worn repeatedly (because the gloves may have lost their ability to defend against harmful substances).
