NRL) come primarily from the proteins present in natural rubber latex. Synthetic latexes do not contain any of these naturally occurring proteins and therefore, by definition, are free of protein allergens. However, most of the commercially used synthetic latexes may not provide the desired comfort or have the high performance properties of natural rubber. Switching from NR to synthetics may not be straightforward and production adjustments are required. The other factor is cost. Mostly, these latexes are used as a single component. But possibilities exist that mixing two or more of these latexes may provide a system that can be both economically attractive as well as satisfactory for the consumers and manufacturers.
