Natural foam blowing products (oxygen-free nitrogen and CO2)

BOC has been supplying compressed gas to a wide range of industries for many years.

Oxygen-free nitrogen (OFN) and carbon dioxide (CO2) are products that have applications in the foam-blowing industry, mainly in the production of flexible foam.

OFN is also used to 'inert' enclosed spaces and to provide a protective blanket over flammable liquids.

CO2 can be used as a powerful fire extinguisher in unmanned, enclosed spaces (compactors).

BOC can offer a wide range of solutions.

Hydrocarbons Natural foam-blowing agents HFCs
Cyclopentane Carbon Dioxide HFC 152a
Isopentane Oxygen-free nitrogen HFC365/227
N Pentane   HFC245


We can offer a wide choice of package sizes from small sample cylinders, to 1000l drums and bulk deliveries. This allows us to support customers through from the trial stage to full production.

Security of supply

At BOC we work with a number of the world's most recognisable chemical producers to offer the full range of foam-blowing products.

In addition to this product range, BOC have blending facilities on our site in the UK which allows us to  offer bespoke blended products with a vapour pressure of anywhere between 30 and 110 psig at 21ºC (70ºF) to suit individual customer requirements.


BOC offers the full range of fluorocarbons including:

  • HFC134a
  • HFC152
  • HFC152a
  • HFC227ea.

These products offer the advantages of:

  • low flammability
  • ease of handling
  • zero Ozone Depleting Potential (ODP)
  • low Volatile Organic Compound (VOC) potential.

Dimethyl ether (DME)

DME has many attractive properties for use in a wide range of applications:

  • thermal, chemical, and hydrolytic stability
  • an excellent solvent
  • miscible with water and alcohols
  • popular with formulators due to its zero ODP
  • potential to lower the VOC content of the aerosol
  • excellent solvent for resins, thus popular in products such as hairsprays and paints
  • superior expansion from liquid into vapour state makes it popular for deodorants, perfumes, and air fresheners.

Atmospheric compressed gases

For over a century BOC has been one of the world's leading suppliers of atmospheric gas products.

We recognise that with changes in aerosol regulations, developments in technology, and an increase in concern for the environment, compressed atmospheric gases may become more relevant as propellants.

BOC has a superb infrastructure for the supply of these gases, coupled with a first-rate understanding of the aerosol industry. With our knowledge and capabilities, we are confident we can support industry needs for these non-toxic, non-flammable, and non-VOC gases.

Bespoke blends

BOC has the capability to blend any number of individual raw materials to your exact mixture specification and pressure. We have worked with many aerosol producers to develop innovative formulations, including blends for post-foaming aerosols.

All of the available propellant components including butane, isobutene, propane, pentanes for solvent characteristics, DME, and fluorocarbons are stocked and readily available for blending.

Whether you require a new sample or a multi-component bulk blend, BOC can supply the mixtures to your exact specification.

Package range

Whether your requirements are for research and development work, short filling runs, or large-scale continuous production, BOC offers the full range of propellants and propellant blends in all package sizes - from sample cylinders to 1000-litre drums and bulk supply.

Our aim is to optimise your inventory holding and handling requirements while minimising change-over downtime, costs and safety risks.
