Fire Retardant Testing

Intumescent Chemicals is the newest member of the Smoke & Fire Curtains family. Based on the Nottinghamshire / Derbyshire border Intumescent Chemicals specialise in fire resistant testing and research and the development of intumescent liquid flame retardants (LFRs).


Fire Retardant Products

Intumescent Chemicals are leading manufacturers of intumescent product ranges offering, within the passive fire industry, a large range of fire-resistant adhesives, composites, polyurethane, mastics, sealants, foam injection as well as compounds for sealing and preventing the spread of smoke and fire.

Our products include:

  • Phyrolex™
  • Epoxy Prepreg
  • Polyester Composites
  • Phenolic Composites
  • Phenolic Foam
  • Polyurethane Foam
  • Polyisocyanurate Foam


We are also able to formulate completely bespoke products to suite specific application sectors and, unlike other companies, we undertake all research and development in-house ensuring that we keep our customers ahead of their competition.

Our range of fire-resistant products can be used in many application types within a large array of sectors including:

  • Aerospace
  • Marine
  • Automotive
  • Building Construction
  • Railway Rolling Stock
  • Oil and Gas


All our products have been in-house tested to industry standards.  Our products are easy to apply for both horizontal and vertical sections and make an excellent adhesion to common building substrates as well as offering the required fire resistance.


Fire Test Certification Programmes

We are also able to supervise and advise on Fire Test Certification Programmes and have a range of furnaces and indicative test equipment to simulate most fire tests currently in use in the UK, Europe and the USA.  This equipment is all standardised to predict performance under full scale fire testing.

We are happy to assist our customers with the design and operation of Fire Test Certification Programmes.  This service is invaluable to companies new to the field as failure at the end of a project can be very costly indeed.  By working with Intumescent Chemicals we enable our customers to achieve early entry into the intumescent and fire retardant coatings market without the time and cost needed to build up their own in-house methods and products.

In short, in fire testing there is no substitute for experience and our experience covers over 25 years.  Intumescent Chemicals is a market leader employing R&D chemists and maintaining a full and sophisticated laboratory with a full inventory which is substantially and constantly updated in order to investigate new areas of the market.
