Takeaways

Polyurethane foam is not toxic in and of itself. Off-gassing in polyurethane foam products may induce health risks for consumers, but there are methods of prevention.

Polyurethane Foam Background

Polyester-based polyurethane foams first entered the market in 1937. They belong to a class of compounds known broadly as polymeric foams. PE-PUR foam is popularly used for insulation, structural, and comfort purposes. A common application is within ventilator and CPAP machines.

Toxicity of Polyester-Based Polyurethane Foams

PE-PUR foams are formulated using isocyanates. Isocyanates are a family of chemical compounds that are characterized by a high reactivity and low molecular weight. They’re often used in the production of polyurethanes, however, isocyanate exposure can have adverse health effects.

Carcinogenic Properties of Isocyanates

Over the past 30 years, research has also linked isocyanate exposure to cancer. Studies haven’t explicitly named PE-PUR foam as a carcinogen. Though there have been other isocyanate-containing products identified as carcinogenic. Given this tangential relationship, further investigation into PE-PUR foam’s carcinogenic potential is wholly warranted.

Philips Recall of CPAP and Ventilator Machines

In June 2021, Philips announced a voluntary recall of several of its sleep apnea devices and ventilators. The recall targets between three and four million devices. Philips explained the devices use a PE-PUR sound abatement foam that could degrade into particles or off-gas chemicals.

Off-Gassing Danger: Diethylene Glycol

Diethylene glycol (DEG) is among the chemicals released by PE-PUR foam on Philips devices. DEG is a highly toxic, colorless, odorless chemical. It’s often used in antifreeze, brake fluid, and lubricants. Exposure to diethylene glycol can have severe effects. Health complications range from nausea and vomiting to coma or even death.

Polyurethane Foam Degradation Danger

Beyond external factors, PE-PUR foam is also susceptible to microbial degradation. Common airborne bacteria can play a role in decomposition. The presence and impact of certain bacteria will depend on the environment where the devices were used. Bacterial factors will be less prevalent in well-maintained healthcare facilities.

Is Polyurethane Toxic?

Yes, polyurethane is toxic. Uncured polyurethane is not safe and can irritate people with respiratory problems. However, that does not mean you are putting anybody at risk. As long as you apply polyurethane correctly, whether it is oil-based or water-based, you and everybody around the product will be safe.

What Makes Polyurethane Toxic?

The chief components that make polyurethanes toxic are volatile organic compounds (VOCs), which are chemicals that are emitted as gases. VOCs are released by many household products that contain chemicals such as sprays, pesticides, air fresheners, permanent markers, glues, copiers and printers, and so many others.

What Effects Would VOCs Have on my Health?

Is polyurethane toxic to humans? Well, under normal conditions, VOCs don’t have adverse effects on people. However, under intense and prolonged contact, they can be toxic and have been shown to cause health issues like asthma, nausea, and headaches, amongst others.

Can Polyurethane Fumes Kill You?

No, polyurethane fumes cannot kill unless you have a severe allergic reaction. As mentioned earlier, constant and intense exposure to high levels of VOCs can have adverse effects. These high levels are rare in household products unless you stick your head in a can for hours.

What do I do if Polyurethane Falls on My Hand?

If polyurethane gets on your hand, use some mineral spirit to remove polyurethane from your hands. For water-based polyurethane, all you’ll need is soap and water.

The Problem With Polyurethane Foam

Actually, there are several problems. For one, polyurethane foam derives from petroleum, which is not sustainable. It is therefore not environmentally friendly, but that’s the least of your worries.

Additional Concerns

In passing Proposition 65 in 1986, California led the nation in identifying chemicals around the house — including toxins in furniture — that cause cancer, birth defects, or reproductive issues.

What are the ingredients in polyurethane foam?

However, virtually all flexible polyurethane foams contain a few basic ingredients: Polyols are the basic building blocks of memory foam. These are molecules that contain more than one alcohol chemical group, called a hydroxyl group. Polyols are organic compounds and can be found in everything from sugar to plastic.

What is the chemical compound that reacts with polymers to make foam?

Polyols are organic compounds and can be found in everything from sugar to plastic. Diisocyanates are a type of chemical compound that chemically reacts with polymers to produce polyurethane foam. Toluene diisocyanate (TDI) and methylene diphenyl diisocyanate (MDI) are the most common diisocyanates used in memory foam.

What are the chemicals in memory foam?

Common harmful chemicals that were historically found in memory foam mattresses include: 1 Methylbenzene: Methylbenzene, more commonly known as toluene, is a clear liquid that occurs naturally in crude oil. Toluene is toxic when inhaled in large quantities. 2 Formaldehyde: Formaldehyde sometimes results as a by-product of the foam manufacturing process, though this is much less common nowadays. Formaldehyde fumes can irritate the eyes, nose and mouth, and it is known to be a human carcinogen. 3 Methylene Dianiline: Used as a reactant in the foam manufacturing process, methylene dianiline causes irritation when coming into contact with skin, and may be carcinogenic. 4 Methylene Chloride: Formerly used as a blowing agent, this substance is a suspected carcinogen and can pose serious health risks if it comes into contact to the skin or mucous membranes. 5 Chlorofluorocarbons: Chlorofluorocarbons were formerly used as a blowing agent, but use of these substances is now limited because of their ozone-depleting effects.

What is memory foam?
