POLYURETHANE FOAM WITH HIGH SUPPORT FACTOR AND AIRFLOW

摘要

Latex foams are perceived as a "premium" foam product for mattresses toppers and pillows but at the same time, the labor and energy intensive including several production steps process requiring moulds, freezing, vulcanizing, washing to remove additives and then drying besides to be presented generally higher density and cost than PU. This project defines the main global performance requirements for latex-like or PU-latex foams in terms of density, hardness, durability, support factor, touch etc. The latex-like system formulation developed by DOW, meets customer requirements and uses polyols and additives commercially available and has presented properties very similar to latex foam.
