2. Polyvinyl chloride (PVC) gloves

The gloves are allergen-free, powder-free, low dust generation, low ion content, strong anti-chemical corrosion ability, can protect almost all chemical dangerous goods, and also have anti-static properties. The thickened and treated surface (such as the rough surface) can also prevent general mechanical abrasion, and the thickened type can also prevent cold, and the operating temperature is -4℃~66℃. Can be used in a dust-free environment.

Classification standard for PVC gloves:

A grade product, no holes on the surface of the gloves (powder pvc gloves), uniform powder quantity, no obvious powdery, transparent milky white color, no obvious ink spots, no impurities, and the size and physical properties of each part meet customer requirements.

Grade B product, slight stains, 3 small black spots (1mm≤diameter≤2mm), or small black spots (diameter≤1mm) in large numbers (diameter>5), deformed, impurity (diameter≤1mm), slightly colored Yellow, serious nail marks, cracks, and the size and physical properties of each part do not meet the requirements.

Silicon-free, with certain antistatic properties, suitable for the production needs of the electronics industry. Low surface chemical residue, low ion content, small particle content, suitable for strict clean room environment.

5. Neoprene gloves

Similar to the comfort of natural rubber, neoprene gloves are resistant to light, aging, flexing, acid and alkali, ozone, burning, heat and oil.

6. Butyl rubber gloves

Butyl rubber is only used as a material for medium-sized unlined gloves, and can be used as a glove box, anaerobic box, incubator, and operation box; it has superfluous acid, aqua regia, nitric acid, strong acid, strong alkali, toluene, alcohol, etc. Strong durability, chemical resistant liquid gloves made of special rubber.

7. Polyvinyl alcohol (PVA) gloves

Polyvinyl alcohol (PVA) can be used as a material for medium-sized lined gloves, so this kind of gloves can target a variety of organic chemicals, such as aliphatics, aromatic hydrocarbons, chlorinated solvents, fluorocarbons and most ketones (except acetone), Esters and ethers provide a high level of protection and corrosion resistance.
