resin composition for rubber gloves without sulfur at brazil
Latex Specifications and Properties | Sciencing
Latex is generally made up of around 55 to 65 percent water and 30 to 40 percent of rubber material. It also may contains sugar, resin, protein and ash. When latex is processed into a workable material like a surgical glove, it undergoes exposure to sulfur, carbon black and oil.

The gloves are then dried and cured, which is where Charles Goodyear’s enormously important discovery enters the process. Vulcanization converts the gloves to an elastic state by causing a reaction between rubber molecules in the latex and chemicals that have been added, and gives gloves their elasticity so they are less likely to tear.

Natural rubber
Natural rubber, also called by other names of India rubber, latex, Amazonian rubber, caucho or caoutchouc, as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds, plus water. Thailand and Indonesia are two of the leading rubber producers. Forms of polyisoprene that are used as natural rubbers are classified as elastomers.

How latex is made - material, production process, making
The composition of latex sap consists of 30-40% rubber particles, 55-65% water, and small amounts of protein, sterol glycosides, resins, ash, and sugars. Rubber has high elasticity and a polymer molecular structure.

Effects of sulfur-based hemostatic ... - PubMed Central (PMC)
Sulfur in the sulfate solutions, contrarily to that found in latex gloves, has greater electrical stability, saturated by oxygen atoms, less reactive, and, therefore, incapable of reacting with metal catalysts 8. For this reason, the mere presence of sulfur does not give the material any inhibitory properties.
