In recent years, alarming headlines and discussions about the presence of polyurethane in everyday products have become more frequent online. For many, the very sound of the word brings to mind a chemical toxin that threatens the health and safety of households. As a result, a kind of “polyurethane panic” has emerged—fueled by incomplete information, misunderstandings, and often by marketing strategies.
The aim of this article is to examine the facts, confront popular myths, and answer the question: should we really be concerned when a product description includes the word “polyurethane”?

Where does the panic come from?
Why do people react to the word “polyurethane” as if it were poison?
The fear surrounding the term “polyurethane” doesn’t come from nowhere. In collective perception, many complex, technical chemical names automatically trigger associations with toxins or hazardous substances. This comes from a natural defense mechanism—if something sounds “chemical” and isn’t familiar from daily life, we instinctively treat it as a threat. On top of that, polyurethane is part of the group of plastics, and the very category of “plastics” often carries negative associations, mostly due to the waste problem and the harmfulness of substances used in the past (e.g., asbestos or bisphenol A).
Sources of fear and online misinformation
The internet has greatly contributed to the growth of unfounded fears. Blogs, forums, and social media often repeat unchecked claims. Popular posts and articles with titles like “Avoid polyurethane at home—it’s poison!” are usually based more on emotions than evidence. Common myths include:
-
that polyurethane “releases toxins throughout its use,”
-
that it is “as harmful as asbestos” or “just as dangerous as formaldehyde,”
-
that simply touching a surface containing polyurethane means “absorbing” dangerous substances.
None of these claims are supported by scientific research. They are oversimplifications or misinterpretations of production-related facts wrongly applied to finished products.
Polyurethane as an easy marketing scare tactic
The market also plays a significant role. In marketing, fear is a powerful sales tool. Simply stating that a product “contains no polyurethane” or “is 100% natural” can give it an aura of safety and quality in the eyes of consumers. It’s a simple trick: if something is free from a substance that sounds “chemical,” it must be better. Unfortunately, this kind of narrative reinforces unfounded fears and fuels misinformation.
As a result, a “polyurethane panic” has emerged—driven more by myths and manipulation than by scientific facts.
What exactly is polyurethane?
A short introduction to the material
Polyurethane (PU for short) is a type of plastic created through a chemical reaction between polyols and isocyanates. It may sound complicated, but in practice, these compounds—once combined and cured—form a highly stable, durable, and flexible structure. This variety of properties is what makes polyurethane one of the most widely used materials in modern industry.
Depending on the formula and production process, it can be soft and flexible (e.g., mattress foams), hard and resistant (e.g., protective coatings), or even transparent and aesthetic (e.g., varnishes). Thanks to this range of possibilities, it’s hard to find another material with such a broad scope of applications.
Everyday applications
Polyurethane surrounds us daily, often without us realizing it. It can be found in:
-
Furniture – upholstery foams that provide seating and sleeping comfort.
-
Footwear – lightweight, flexible, and durable PU soles.
-
Clothing – coatings in jackets or sports gear that protect against wind and rain.
-
Insulation – mounting foams and thermal insulation used in construction.
-
Automobiles – interior elements, seals, and soundproofing foams.
-
Electronics – protective coatings shielding components from moisture and damage.
-
Floors and panels – coatings and adhesives that enhance durability and wear resistance.
It’s important to note that most people use products containing polyurethane every single day — without the slightest risk to their health. If it were inherently dangerous, it would be hard to imagine such widespread and long-term use across so many industries.
Polyurethane in cork products
How much is really there?
In cork products, the share of polyurethane is very small. It usually makes up less than 10% of the product — and often even less. The vast majority is natural cork, a material obtained from the bark of cork oak trees. Polyurethane is therefore not the main ingredient but only a technological additive.
Its role as a binder, not a main component
In cork, polyurethane serves as a binder. It bonds the cork granules into a solid, durable whole, giving the product mechanical strength and long-lasting performance. Thanks to a small amount of PU, cork panels and underlays retain their properties for years without breaking apart or crumbling.
The difference between “raw” and “cured” polyurethane in finished products
Raw polyurethane — the production stage
During the production of polyurethane, so-called reactive ingredients are used — polyols and isocyanates. These compounds, before reacting with each other, can be irritating and therefore require strict safety measures in manufacturing plants. For this reason, factories enforce rigorous safety protocols, ventilation systems, and personal protective equipment. In other words, in its raw state, polyurethane is “active,” chemically reactive, and does require caution.
Cured polyurethane — the finished stage
Once the reaction and curing process are complete, a completely different substance is created — stable, insoluble, and chemically neutral. This cured polyurethane is what enters our homes in the form of foams, binders, or coatings. In this state, it does not release any harmful substances. That’s why finished products such as cork panels or furniture are safe and meet quality and sanitary standards.
Factory vs. living room — a simple comparison
It’s similar to paint or glue: while painting or gluing, they give off strong odors and require ventilation and caution. But once dried and cured on a wall or inside furniture, they become neutral and safe. The same applies to polyurethane — the risk exists only during production, not in the finished product.
What may pose a risk in a factory has no relevance in your living room. Cured polyurethane serves only as a stable binder or structure, without affecting everyday use.
Summary
The so-called “polyurethane panic” is largely the result of misunderstandings, oversimplifications, and marketing tactics exploiting fear of complex chemical names. In reality, polyurethane is an extremely versatile material, present in countless everyday products — from mattresses and furniture to shoes, electronics, and car parts.
In cork products, it plays the role of a technological additive, acting solely as a binder that holds cork granules together. The key distinction is this: while polyurethane components in their raw form can be irritating in a factory setting, in the cured state they are stable and safe.
In conclusion: the presence of polyurethane at home is no reason for alarm. In finished products, it is a neutral structural component, not a “chemical bomb” as some sensational headlines suggest.
FAQ
1. Is cured polyurethane toxic?
No. In its finished, cured form, polyurethane is stable and chemically inert. It does not release toxic substances under normal usage conditions.
2. Why are there warnings about polyurethane online?
Most concerns come from confusing the raw ingredients of polyurethane (which indeed require caution in factories) with the finished material. Fake news and simplified articles often wrongly transfer production risks into the home.
3. Is polyurethane the main ingredient in cork?
No. In cork products, it makes up only a small fraction of the total volume and serves as the binder holding cork granules together.
