When rubber latex is tapped from the para tree, it comes out with a solid rubber concentration of 25 – 40%. Blending with latex from a variety of other sources brings the concentration to the industry standard of 35%. Water is then removed from this blend by centrifuge to increase the concentration to 60%, and the various aforementioned chemicals are added to control coagulation and prevent bacteria degradation. The final concentrated rubber latex is sold to rubber products manufacturers to make dipped rubber products (those products made with molds).
