Case story database

Search for Successfully Implemented Alternatives

You can use the free text search function to find information in the case story database. Most suitable are: substance name and other substance identifier (EC- and CAS-number). You can refine your search after first entry for sector-, function- and process-categories. The case studies are meant to serve as source of inspiration and ideas for substitution. The alternatives are constantly being developed further. We therefore recommend that you to check in each individual case whether an alternative is suitable for your applications and purposes. If you are aware of any other relevant information that is not mentioned in the current case story, please contact SUBSPORTplus.

Fire resistant composition in particular for energy or telecommunication cables.

The substitution originates from a patent registration filed in 2006 concerning the substitution of different halogenated polymers used as flame retardants with non-halogen thermoplastics with cork as a fire retardant filler. By mixing in cork in the composition the heat release rate for the polymers decreased significantly, resulting in a more flame resistant material.

Evaluation of halogen-free flame retardants in polypropylene formulations as alternatives to flame retardants containing halogens.

This document concerns an evaluation of several halogen-free flame retardants. The evaluation also presents some new types of flame retardants, which are fully functional, commercially available and cost-efficient alternatives to traditional halogenated flame retardants. The details, strengths and limitations of all alternatives are listed below.

Fire-resistant and flame proof coating for polymeric thermoplastics and thermoset resins.

A surface coating consisting of fire retarding and smoke suppressing constituents dispersed in an essentially non-toxic, water based adhesive binder. The entire invention therefore consists of six different functional groups which respective functions will be explained below, the different groups are: catalyst/initiator, expendable graphite, source of carbon which additionally forms water, a blowing agent, cement and ceramics.

Decabromodiphenyl ether flame retardants in plastic pallets; A safer alternatives assessment

This is a report comparing evaluating the alternatives to plastic pallets containing DecaBDE for flame retardancy. The investigations evaluate different materials and chemical flame retardants and also investigate if fire safety measures would eliminate the need for flame retardants in plastic pallets. The green screen for safer chemicals was used to evaluate the hazards of the chemical alternatives, and two of the investigated chemicals were found to be safer than DecaBDE: magnesium hydroxide and a proprietary phosphorus based substance. In addition, wood passed the fire safety test.

DecaBDE and Alternatives in Electrical and Electronic Equipment (EEE)

The case summarises information from a report from Danish Environmental Protection Agency (EPA) on the use of the brominated flame retardant DecaBDE in electrical and electronic equipment (EEE), and describes suitable alternatives to Deca-BDE. The study has not identified any application of Deca-BDE in EEE for which substitution is not possible, from the scientific or technical point of view. The report lists 25 alternative substances. Some of these are halogenated and will not be listed in this case description.

Guidance on alternatives to the flame retardant Pentabromodiphenylether.

Commercial PentaBDE is a brominated flame retardant that is likely to cause significant adverse effects on human health and the environment. Components of c-PentaBDE are widespread in the global environment and poses risks to health and the environment. There are toxicological and ecotoxicological data gaps for the potential alternatives to c-PentaBDE. However, the data available clearly show that there are commercially available alternative flame retardants that are less hazardous than c-PentaBDE.

An alternative engineering plastic completely free from brominated flame retardants, PVC and plasticizers for electronics.

Stanyl® ForTii, produced by DSM, is an engineering plastic completely free of halogens, BFR´s (brominated flame retardants), PVC, red Phosphorus and plasticizers. The applications of the plastic are mainly in components for electronics, such as connectors and sockets, relays and semiconductor packages.Although this engineering plastic is free from any brominated or chlorinated flame retardants, it possesses equally good flame retardancy, as well as chemical and temperature resistance.
