The parameters including physico-chemical properties such as dry rubber content (DRC), total solids content (TSC), volatile fatty acid (VFA) number, alkalinity (ammonia content) and potassium hydroxide (KOH) number and physical properties such as viscosity and cross-link density are important to the trading and processing of natural rubber latex and its products. The typical physical properties of natural rubber products are very similar to those of natural rubber latex, but are not exact due to differences in the compounding and processing cycles.
