Real natural latex pillow is made of 100% pure natural juice from rubber tree through all physical process processing (collection - > mould - > baking - > water), so the latex pillow is absolutely natural and environmentally friendly. The so-called natural latex refers to the liquid flowing out of rubber tree during tapping, which is milky white, solid content is 30%-40%, and rubber particle size is 1.06 micron on average. Fresh natural latex contains 27% - 41.3% (mass), 44% - 70% water, 0.2% - 4.5% protein, 2% - 5% natural resin, 0.36% - 4.2% sugar and 0.4% ash. Ammonia and other stabilizers are often added to prevent natural latex from coagulating due to the action of microorganisms and enzymes.
