Hi Martina,
[quote]I had an impression that LI makes only 100% natural Talalay, so I am glad you pointed out that Talalay from LI could be blended. Thank you.
After searching blended Talalay in this forum, I am still not sure … How much (%) natural latex is in blended Talalay? Again I am looking at BB topper, which is from LI. So a blended Talalay latex from LI would have the same % of natural latex, regardless of who you buy from? Is there a difference in quality among blended Talalay foams? (e.g. LI’s blended Talalay is better than XX’s blended Talalay.)[/quote]
The large majority of Talalay latex used in mattresses (probably more than 90%) is blended rather than 100% natural. You can read a little more about the difference between them in post #2 here. The blend uses approximately 30% natural rubber (NR) and 70% synthetic rubber (SBR).
You can read more about this in post #2 here. I don’t think there would be much difference between them although I would give the edge to natural rubber because it has some anti fungal properties which can affect the dust mite population along with mold and mildew. I have often seen the claim that natural latex is naturally antibacterial but I haven’t seen any specific evidence of this outside of the addition of nanosized particles of Zinc Oxide used as a gelling agent for the latex or the addition of other additives such as silver nanoparticles to the latex. some types of bacteria can spoil the raw latex material when it comes from the tree so they generally add a few drops of ammonia to the latex when it is collected to prevent putrefaction of the raw material.
