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.
