Latest news: TCPP – Category 2 Carcinogen

TCPP is a halogen-based chemical compound commonly used as a flame retardant in polyurethanes and other plastic materials. The latest news regarding this substance is that it will change its classification under REACH, being placed in the category of suspected carcinogen (Carcinogen Category 2 / H351-Suspected of causing cancer).

How TCPP is used

In polyurethanes, TCPP is often incorporated during the manufacturing process to improve the material’s fire behavior.
This is particularly important in applications where fire safety is a priority, such as in the construction, transportation and furniture industries.

TCPP acts as a flame retardant because, when exposed to high temperatures, it decomposes by producing chemicals that interfere with the combustion reaction, thereby slowing the spread of fire.
This helps to provide more passive-type protection and reduce flame damage.

TCPP - Category 2 carcinogen

From the latest results made public from carcinogenesis studies by the U.S. National Toxicology Program, TCPP will be labeled as of June 2024 as a Category 2 carcinogen.

Therefore, the TCPP substance becomes part of those CMR (Carcinogenic – Mutagenic and Toxic for Reproduction) substances, such reclassification could result in additional obligations under other regulations.

What may be the alternatives?

TCPP, can still be used, with some extra precautions after its classification as a Type 2 Carcinogenic product.

However, we at Europoliuretani have preferred to opt for more sustainable solutions.

More than a year ago we replaced TCPP in our polyurethane systems by creating totally “Halogen Free” products, employing alternative substances to maintain high fire reaction perfomances while remaining respectful of the environment and human health. This has been made possible by introducing phosphorus-based molecules as the main flame retardant agents.

This makes it possible to create an innovative and more sustainable polyurethane system, creating a safer working environment for those who work with our materials.
