Ensuring the UV Stability of Polyurethane Foam Technical
1. Introduction Polyurethanes (PUs) are used as coatings, adhesive, sealants, elastomers (CASE), and fibers as well as flexible, semi-rigid and rigid foams [1–3].... They are rarely used to make flexible polyurethane foam. Discoloration from oxidation (Gas induced): Polyurethane foams will discolor if oxidized. Oxides of nitrogen from tow motor emissions, gas fired furnaces or pollution can cause a foam to oxidize and become yellow. This phenomenon may be more observable in the winter when warehouses are closed up and gas furnaces are in operation. Ozone

Flexible polyurethane foam appears to be a simple product, but it is actually very complex. It can be produced to have an almost infinite variety of properties. Even though two foams may look exactly alike, they may feel and perform entirely differently. However, the properties of foam can be identified and specified very precisely. The foam industry utilized a number of measurements and tests...
The most of polyurethane flexible foams are open-cell foams except for the microcellular class foams. The cell structure of polyurethane foam must deal with shrinkage force of the contracting gas used in foaming reaction. Open-cell flexible foam is formulated to create cell structure to let outside air to balance the air pressure between inside and outside of the foam.

  • Premium quality water blown flexible foams that can be used for a variety of industrial, special effects and art & crafts and projects.
  • Polyurethane is a softer, open-cell type of foam that is made in varying degrees of firmness. Because the cells are open and not cross-linked, air can flow throughout the foam just like water can flow throughout a sponge. This characteristic makes the foam softer and gives it the ability to absorb shock energy better. It does not try to rebound as quickly as polyethylene, and it distributes
