Know-how in flame protection
Flame protection is extremely important in electrical engineering, construction and transport as well as in the field of textiles. The large number of available additives with their different properties and interactions with polymers demand a high degree of expertise in order to achieve the optimum flame-resistant finish for the plastic components. Our team brings its many years of experience and expertise in the development and production of flame-retardant masterbatches and compounds to bear and will develop the best solution customized to your specific application.
Free of halogens
Our masterbatches guarantee comprehensive flame protection for polymers – in compliance with many national and international regulations. Ecological aspects are increasingly directing developments in the field of flame protection towards halogen-free solutions. We supply corresponding alternatives on the basis of phosphorus and/or nitrogen, allowing you to provide an efficient and halogen-free finish for your components.
These flame retardants act using a variety of chemical or physical mechanisms. Certain active substances, for instance, work by cooling while others function by diluting or forming a protective layer. Generally the required quantity of active substance is significantly higher than that for comparable systems based on bromine, which can also be detected by a more prominent change in mechanical properties.
Typical flame retardants
|Halogenated||Organic bromine compounds, chlorinated compounds|
|Halogen-free||Mineral-based flame-retardant additives (aluminium trihydrate, magnesium hydroxide), organic phosphorus compounds, nitrogen-based flame-retardant additives|
Halogenated LUVOBATCH® FR products
Halogenated flame retardants act in the gaseous phase by interrupting the radical reactions. The energy-rich H and OH radicals produced in the event of a fire are neutralized and are thus made unavailable for further reactions. Brominated flame-retardants are the most effective, in terms of both performance and costs, and can be used for practically all applications. This high level of efficacy means that the additional properties of polymers with this flame-resistant finish are less adversely affected than in other systems.
Compounds with and without halogens
Some fire safety requirements such a UL94 V0 are very difficult to achieve with masterbatches. For this reason, we supply compounds based on halogenated and halogen-free flame retardants that can be used directly to meet these demanding applications.
- No metering
- High product reliability
- Ease of handling
- Reduced flexibility
- Possibly higher costs
