According to the type of flame retardant nylon can be divided into: halogenated flame retardant and halogen-free flame retardant. The application of halogenated flame retardant in our country for many years has also contributed to the birth of flame retardant nylon. However, with the progress of science and technology and the requirements of global living environment, halogen-containing flame retardant nylon release harmful substances to the environment when burning, and many countries have banned the use of flame retardant. Halogen-free PA flame retardant become the new products.

Halogen-free nylon flame-retardant is considered as an efficient and environmentally friendly material. It not only has good mechanical properties, but also improves the flame retardant of the material, can make the material more widely used, has a good flame retardant effect, more important is no harm to the environment.

Red phosphorus and melamine salts are widely used in halogen-free flame retardant nylon. This product has excellent flame retardant performance, flame retardant grade up to ul94v, with low precipitation, drip resistance, high electrical performance and heat resistance, high CTI value, good electrical performance, high impact strength, environmental protection and other characteristics. Suitable for electrical connectors. Brominated flame retardants and RoHS were added to improve the flame retardancy of the composites. Including ul-94v-o testV-1and V-2 test. The processing temperature of granular nylon is 500F (260℃).

Based on the traditional halogen-free nylon flame-retardant,the modified halogen-free flame-retardant nylon was used to improve the mechanical properties and flame-retardant properties of the product. The most important is to completely improve the halogenated flame retardant pollution to the environment.
