Latex gloves are made of natural latex with other fine additives. The industrial natural latex comes from Brazil Hevea rubber tree. The dry matter in the fresh latex obtained from rubber tree tapping accounts for 25%-45% by weight, and more than 90% of the dry matter is made of cis-1,4-polyisoprene. Rubber hydrocarbon composed of olefin, other non-gel components include protein, lipid, acetone soluble matter, water soluble matter and inorganic salt. The varieties of natural latex gloves mainly include examination gloves, surgical gloves, household gloves and industrial gloves. The specific features and uses are as follows:
(1) Natural latex examination gloves and their uses
Natural latex inspection gloves are characterized by no distinction between left and right hands and thin film.

There are 2 kinds of gloves; according to the packaging, there are 2 kinds of sterilization and non-sterilization; according to the impermeable AQL value, there are 2 kinds of medical examination gloves and industrial examination gloves. According to the palm width size, the inspection gloves are divided into three specifications: S, M, and L, and consumers should choose according to their needs.
(2) Natural latex surgical gloves and their uses
Surgical gloves are divided into left and right hands, divided into two types: powdered and powder-free. Sterile packaging, for one-time use, for the operation of aseptic operating room.

They are resistant to common acids and alkalis and other general media. They can be used repeatedly after washing and drying after use.
Natural latex gloves have good strength, flexibility, elasticity and comfort, and can isolate viruses and bacteria. However, due to the molecular structure of natural latex, natural latex gloves are not resistant to oil, organic solvents and hydrocarbons. Natural latex products are resistant to tearing. Poor performance. At the same time, due to the natural latex and natural latex gloves containing water-soluble protein, some wearers have allergies, manifested as skin itching, inflammation, pimple, long blisters and even anaphylactic shock or death.
