Polyurethane foam is used to make car seats comfortable, as well as even aid in the outside structure of the car by making bumpers, spoilers, doors, windows, etc. 1. Unlike polyurethane, latex is less likely to emit high levels of VOCs. FPUF were covered with FR and non-FR fabrics to simulate cushion conditions. Mattresses and all Baby Products are Exempt. Look for a product that has 100 percent natural latex. Second, they break down over time, causing major off-gassing of VOCs into the air you breath. The pictures above are examples of open cell and closed cell foams under a microscope. In addition to their flammability, polyurethanes form carbon monoxide, hydrogen cyanide and other toxic products on decomposition and combustion. Their development continued commercially in Germany, even-tually leading to a global multibillion dollar industry (Vilar 2002). Polyurethane foam comes in many different kinds, and it’s in tons of stuff. While its toxicity in mammals and the effects of long-term exposure are unknown, it is toxic in aquatic environments. Thanks to innovative alternatives to the ubiquitous toxic polyurethane coatings, this fact is gradually changing. This variant of polyurethane foam is also used in the manufacture of automobile seats and also in the manufacture of carpet cushions. While polyurethane foam uses insulating gases such as HCFC and CFC, these gases are more hazardous for the environment. And third, they are extraordinarily flammable. Reasons Foam Fails #1 Dangerous Toxic Ingredients The chemical companies selling polyurethane foam as green and sustainable, demonstrate chutzpah second only to that of the tobacco and coal industries. Polyols are a family of chemicals and they can be made differently to reduce potential harm. If it contains polyurethane foam, it cannot be “toxic-free” due to the chemical makeup of the foam itself. For instance, some polyols are made from vegetable oils but be sure to do your research carefully. Although no other U.S. states have a similar standard, because California has such a large market many manufacturers meet TB 117 in products that they distribute across the United States. Polyurethane is widely used, with its two major applications, soft furnishings and insulation, having low thermal inertia, and hence enhanced flammability.
