Halogen-free flame retardant, also known as halogen-free low smoke environmental protection flame retardant or green environmental protection inorganic flame retardant materials, the main characteristics include the following aspects:
First, environmental protection
Halogen-free: Halogen-free flame retardants do not contain halogen compounds, such as bromine or chlorine, which may release harmful substances during combustion. Therefore, halogen-free flame retardants are considered an environmentally friendly flame retardant material that meets many environmental standards and regulatory requirements.
Low smoke and non-toxic: halogen-free flame retardants emit small amounts of smoke when burning, do not produce toxic, corrosive gases, harmless to the human body or minimal harm, and will not cause pollution to the environment.
Second, flame retardant performance
Excellent flame retardant performance: halogen-free flame retardants can effectively inhibit the combustion and flame spread of materials, and meet various flame retardant performance requirements, such as UL 94 flame retardant grade, providing higher fire safety.
A variety of flame retardant mechanism: halogen-free flame retardants through endothermic reaction, covering effect, inhibition of chain reaction and other physical and chemical effects to achieve the purpose of flame retardant.
Third, thermal stability
Good thermal stability: halogen-free flame retardants can maintain stable performance at high temperatures and are not easy to decompose, effectively preventing further combustion.
Fourth, processing performance
Easy to process: halogen-free flame retardants are easy to disperse in plastic materials, do not precipitate, have no corrosion on processing equipment, have good processing fluidity, small proportion of products, and do not precipitate frost.
Small effect on the physical properties of the product: halogen-free flame retardants can achieve good flame retardant effect in the case of less addition, and have little impact on the physical properties of the product.
Fifth, a wide range of applications
A variety of applications: halogen-free flame retardants are suitable for PA, PBT, PP, PET, ABS, PVC and PC+ABS alloys and other materials, widely used in wire and cable, electronic components, precision instruments, building materials, household appliances and other fields.
Sixth, other characteristics
Low price: Compared with some traditional halogen flame retardants, halogen-free flame retardants are relatively inexpensive and come from a wide range of sources.
In line with international standards: halogen-free flame retardants in line with international environmental standards and development trends, is a flame retardant material with wide application prospects.
In summary, halogen-free flame retardants play an important role in the field of flame retardant materials due to their environmental protection, excellent flame retardant properties, thermal stability, good processing properties and wide range of application.
