Project summary

Over the recent years, polymer manufacturers, particularly in the USA, Japan and England, have extensively used phosphorus-based flame-retardants (FR). A major application of FR is olefine polymer-based plastic production. There are three most commonly used classes of FRs: brominated organic FR, inorganic fillers and phosphorus-based organic and inorganic ones. The negative features of the first two classes are the high toxicity of the first and the low efficacy, hence high addition levels, of the second, which is detrimental to the physical and mechanical properties of polymers. Phosphorus-based FR are an alternative to the other types of FR, but are characterized by a relatively low decomposition temperature and moderate FR effectiveness, which sets limits to their use in polymers.

Polymer and polymer compound production is a high-temperature process, which sets rigid standards to the fire-retardants as to volatile matter content and initial degradation temperature.

Most extensively used among non-organic phosphorus compounds are ammonia polyphosphate fire-retardants that decompose at temperatures over 220°, have relatively low FR efficiency and poor compatibility with the polymer matrix.

Firestop has developed BIZONтм - a new FR for olefine-type polymers, which is an aminated organic phosphonate; the company has also developed BIZON manufacturing technology. BIZON has high FR efficiency, good compatibility with the polymer matrix and good processing characteristics, which makes it suitable for usage in polypropylene and its co-polymers, polyethylene, polystyrene, elastomers, etc. BIZON was submitted to a rigorous toxicology testing programme and was registered with ELINCS (in the past – EINECS) as a not-toxic substance, which does not have adverse effects on human health or the environment.

Firestop Chemicals Ltd is a technology transfer company registered in the UK under No 4259637 as of 1999. Its head office is situated in Holmes Chapel in Cheshire and it specializes in the development, manufacture, marketing and sales of new FRs for textile and polymer applications.

The objective of the project is designing a BIZON production (pilot) plant which could be subsequently built at JSC (OPEN TYPE) NITs Khimprom, Volgograd.

OPEN TYPE Giprosintez is the successor to "Giprosintez" State Design Institute of the Ministry of Chemical Industry of USSR, a leading chemical design institute whose scope covered the design of chemical weapons fabrication and destruction facilities. Scientists and technologists who were formerly employed in chemical weapons production will be engaged in the proposed project.


The International Science and Technology Center (ISTC) is an intergovernmental organization connecting scientists from Kazakhstan, Armenia, Tajikistan, Kyrgyzstan, and Georgia with their peers and research organizations in the EU, Japan, Republic of Korea, Norway and the United States.


ISTC facilitates international science projects and assists the global scientific and business community to source and engage with CIS and Georgian institutes that develop or possess an excellence of scientific know-how.
