Natural rubber comes from the sap of the rubber tree but this harvested latex contains many impurities, including certain proteins, which may cause allergic reactions in certain individuals. The latex is not routinely cleaned when it is in this liquid state although this is the most efficient way to wash or purify latex  – not once its coagulated in to solid rubber. The Yulex Pure Process washes the latex in its liquid state thus removing  over 99% of natural rubber’s impurities, including antigenic proteins from our non-sensitizing, hevea-based specialty natural rubber. Using Yulex Pure Natural Rubber for all our foams substantially reduces the risk of allergic reactions. Euphoam provides the cleanest and safest foams available.
