What are latex fillers?
Latex fillers are fine particles of chemically inert materials. They are commonly used to enhance the hardness of latex foam and because they replace some of the natural latex production costs are lower! The most common fillers are China Clay (Kaolin clay), calcium oxide, or titanium dioxide. Very often, latex foam with fillers can be easily identified with un-natural dull white colour or greyish cream colour. Naturelle latex products do not use fillers! Harmful – the insertion of fillers destroys the antibacterial property of Natural Latex. Hence, its presence induces the growth of fungus and bacteria which encourages the habitat of dustmites. Inorganic fillers reduce tensile properties, in particular elongation at break, suppress resilience, promote high long term compression deformation, and reduce the ability to recover to original shape. Pure latex means “no fillers”. The chemicals used should be no more than 6-8% of the total polymeric content. The rest of the constituent should
