Halogen-Free Flame Retardant Masterbatches for Modern Plastics
Fire safety has become an increasingly important requirement in the development and production of modern plastic products. Electrical components, cables, construction products, transportation parts, films, technical profiles, consumer products and engineering plastics may all require controlled flame behaviour without compromising mechanical performance or processing efficiency.
EXTRUTEX develops and supplies halogen-free flame retardant masterbatches and compounds designed for demanding thermoplastic applications. These solutions provide effective flame retardancy while avoiding conventional bromine- and chlorine-based flame retardant systems.
Our HFFR technologies are designed around a combination of phosphorus, nitrogen and mineral-based flame retardant mechanisms. Depending on the polymer, processing technology and required fire classification, the formulation can be tailored to achieve the desired balance between flame resistance, smoke reduction, mechanical properties, surface appearance and processability.
EXTRUTEX combines Austrian design and engineering know-how with manufacturing capabilities in China, including production facilities and technical resources in Nanjing and Shanghai. This structure allows us to provide competitive industrial solutions while maintaining a strong focus on formulation consistency, process stability and technical support.
Key Advantages of Halogen-Free Flame Retardant Masterbatch
Halogen-free flame retardant systems are developed to provide effective fire protection with improved environmental and safety characteristics. The exact performance depends on the polymer, formulation, loading level, product design and applicable test method.
01. Low Smoke Emission
Halogen-free formulations can significantly reduce smoke generation compared with many conventional halogen-containing systems. Lower smoke density can improve visibility during a fire and support safer evacuation conditions.
02. Reduced Toxicity & Corrosion
Halogen-free systems avoid the formation of hydrogen halides associated with chlorine- and bromine-containing materials. This can reduce corrosive and toxic combustion products and help protect sensitive equipment and infrastructure.
03. Environmentally Conscious Technology
HFFR masterbatches provide an alternative to traditional halogenated flame retardant technologies. Mineral-based systems using aluminium or magnesium hydroxide can be selected where suitable for the application.
04. Effective Flame Retardancy
Properly formulated flame retardant systems can delay ignition, reduce flame propagation and suppress continued combustion. Formulations can also be designed to minimise flaming drips where required by the application.
05. Controlled Material Performance
EXTRUTEX formulations are developed with attention to mechanical strength, impact performance, melt flow, surface appearance and thermal stability, helping manufacturers maintain the processing characteristics required for production.
06. Wide Polymer Compatibility
Our technologies can be developed for a broad range of thermoplastics, including polyolefins, engineering plastics and specialised polymer compounds.
Advanced HFFR Flame Retardant Technology
Flame retardancy is not achieved through a single mechanism. Depending on the polymer and application, different technologies can act through condensed-phase protection, gas-phase activity, char formation, dilution, cooling or a combination of these mechanisms.
EXTRUTEX develops formulations using carefully selected combinations of phosphorus, nitrogen and mineral flame retardant technologies. The formulation is selected according to the polymer matrix, processing temperature, required flame classification, colour, surface requirements and final product application.
Mineral flame retardants such as aluminium hydroxide and magnesium hydroxide can provide an important flame retardant mechanism by absorbing heat and releasing water during thermal decomposition. Phosphorus-based technologies can contribute to protective char formation and condensed-phase flame inhibition, while nitrogen-based components can support synergistic effects in appropriately designed systems.
The result is a flexible formulation platform that can be adapted to different thermoplastic materials and processing technologies rather than relying on one universal flame retardant recipe.

Designed for Stable Plastic Processing
A flame retardant system must not only provide fire protection. It must also perform reliably during manufacturing. Poorly selected additive systems can influence melt viscosity, dispersion, surface quality, mechanical strength, screw torque and processing stability.
EXTRUTEX therefore considers the entire processing window during formulation development. Masterbatch concentration, carrier compatibility, additive dispersion, thermal stability and feeding behaviour are evaluated according to the target application.
Depending on the formulation, HFFR systems can be supplied for extrusion, injection moulding, blow moulding, film production and twin-screw compounding.
