What does ‘nitrogen expanded foam’ mean and how does it benefit me?

Zotefoams products are manufactured using a truly unique process technology. This involves dissolving nitrogen gas into a plastic sheet at extreme pressures and temperatures. On releasing this pressure and temperature the gas increases its volume to such an extent that it expands the plastic into a foam.

Most of our competitors use either volatile / flammable gases or chemicals / blowing agents which at a certain temperature decompose to produce nitrogen gas (along with other gases such as ammonia). Both of these have negative aspects. The practical benefits are that in emissions studies our foams tend to yield far lower levels of volatile substances. In automotive applications, our foams have among the lowest fogging values in the industry (Fogging is the mist that forms on the inside of your car windscreen over time and is attributable to volatiles in the plastics used in the car interior).

In medical applications the purity is of great benefit for obvious reasons and in packaging of valuable or rare artwork our products have ensured safe transport and storage for many users.
