The difference between medical nitrile gloves and latex gloves

As we all know, nitrile gloves and latex gloves are not the same, they may be used in the same range, then the difference between medical nitrile gloves and medical latex gloves, let me explain below!

 

(1) Material

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 the differences in tree species, geology, climate, and other related conditions, its composition and colloidal structure often appear huge difference. In the fresh latex without adding any substance, rubber hydrocarbons only account for 20% -40% of the total, and the rest is a small amount of non-rubber components and water. The non-rubber components include proteins, lipids, sugars, and inorganic components. Some of them form a composite structure with rubber particles, and some of them dissolve in whey or form non-rubber particles.

Latex gloves

Medical nitrile gloves are the popular name for nitrile gloves. Nitrile rubber is an organic compound and a key raw material for organic synthesis and pharmaceutical intermediates. It is made by emulsion polymerization of butadiene and acrylonitrile. In order to improve the bonding strength and physical and mechanical properties of wet gel and vulcanized rubber, most NBR latex are introduced with carboxyl and other third-party monomers such as acrylic acid and methacrylic acid during copolymerization to be modified into ternary copolymer latex . After modified into NBR latex, the mechanical stability, oil resistance and aging resistance of the latex are significantly improved. Nitrile gloves are made of NBRL by a series of complex processes such as dipping, baking and washing.

(2) Characteristics

 Latex gloves: Compared to nitrile gloves, although the elasticity is better, the toughness, wear resistance, acid and alkali resistance, and grease resistance are slightly worse than nitrile, and it is not suitable for allergic skin and long-term wear.

 

Nitrile gloves: made of 100% NBRL, with poor elasticity, high cleanliness, good abrasion resistance, acid and alkali resistance, and antistatic properties; contains no protein, effectively avoids protein allergies and does not produce skin Allergic phenomenon, suitable for people with allergies to wear for a long time; fingertip hemp design, easy operation, can be used in the processing of precision parts.
