PURE LATEX

1. What is latex?

Latex is the stable dispersion (emulsion) of polymer micro particles in an aqueous medium. It is a complex emulsion consisting of proteins, alkaloids, starches, sugars, oils, tannins, resins, and gums that coagulates on exposure to air. In most plants, latex is white, but some have yellow, orange, or scarlet latex. Latex is not to be confused with plant sap; it is a separate substance, separately produced, and with separate functions.

Latex as found in nature is a milky Fluid found in rubber tree or all flowering plants. The popular is found from rubber tree, which is call Rubber latex.

In physical shape, it is like a milk-like liquid of rubber particles.

 

 

2. Narural Latex v/s SBR

Rubber Latex is divided into 2 types: Natural Rubber Latex and Synthetic Rubber. Each type has its own technical characteristics due to differences in chemical structure between them. 

Natural rubber latex (NR) is harvested from rubber tree, mainly Hevea Brasiliensis (Euphorbiaceae), by tapping method. NR latex is friendly with environment and good for health. With superior elasticity comparing with other materials, NR latex bring comfortable feeling for users.

 

Worker is tapping rubber in Binh Duong province, Vietnam.


Synthetic Rubber (SBR): is formed by the method of emulsion polymerization (a chemical method of synthesizing polymer). Therefore, SBR latex does not have ultimate characteristics as NR. Products made SBR are lower than NR in physics: elasticity, durability, easy to delve (because of low elasticity).
