Hi LatexDude,
I know you’re reevaluating things a bit, so I thought I’d add a bit of information for you about latex and chemicals. All latex foam (including 100% natural Dunlop and Talalay and organic latex) uses a small amount of chemicals to manufacture the latex (see post #18 here) but the manufacturers don’t release the specifics of their compounding formula which is a closely guarded secret.
While I’m not a chemical engineer so I can’t speak to all the differences in their chemical formulations … the two main “chemical” differences between Talalay and Dunlop is that Talalay latex uses carbon dioxide gas as a gelling agent while Dunlop latex uses sodium fluorosilicate. Natural Dunlop latex is also often manufactured closer to the latex plantations so in many cases it needs less ammonia or other stabilizing agents to stabilize the latex and prevent it from coagulating or putrefying before it’s used, while Talalay is made in Holland (Radium) or in the USA (Talalay Global) so the liquid field latex they use may contain higher levels of ammonia or other chemicals to stabilize it before it’s used to manufacture the latex. Most of the ammonia is removed during the foaming process either way.
