5. PVA

Advantages: good chemical resistance, scratch resistance and abrasion resistance, and organic chemicals such as aliphatic, aromatic hydrocarbons, chlorinated solvents, fluorocarbons and most ketones (except acetone), esters and ethers Play an effective protective role.

Disadvantages: When in contact with water, it will be quickly decomposed by water, so do not use it in water or water-based solutions.

6. Neoprene

Advantages: It has a good protective effect on petrochemical products, anti-slip agents, acids, alkalis, hydrocarbons, alcohols, phenols, etc., so it is widely used in chemical and petrochemical industries.

Disadvantages: The cold resistance is relatively poor, so it is not suitable for use in low temperature operating environments.

7. Butyl rubber

Advantages: It not only protects acetone, acetonitrile, dimethylformamide, dimethyl sulfoxide and other substances, but also has excellent resistance to acids and oxidation-reduction solutions other than strong oxidizing concentrated acids, so it is more suitable for use For the disposal of toxic substances in the laboratory.

Disadvantages: poor protection against non-polar solvents.

8. Cloth

Advantages: It can prevent medium and low mechanical wear, and the thickened cloth gloves can be used to prevent heat and cold, so it is more suitable for operations such as heating utensils in the laboratory.

Disadvantages: It can only be used for general protection, and must not be used for chemical protection.

9. Leather

Advantages: It has a certain protective effect on cold, heat, spark splash, abrasion, cutting, and puncture, and has good anti-mechanical wear performance. If it is a thick leather glove, it can prevent heat. If it is coated with aluminum on the outer layer, it can prevent High temperature and heat radiation. Therefore, it is often used in liquid nitrogen operations, welding operations and other occasions.

Disadvantages: It can only be used for general protection, and must not be used for chemical protection.
