The flame retardancy of fluoropolymers is one of many advantages leading to their use in various industrial applications. The Dankai electronics and cable fields rely heavily on fluorine-based materials to delay ignition, reduce dripping and optimize the load of flame retardant additives. DAIKIN advances the performance selection of polymers and modifiers to help manufacturers achieve high safety levels.
1. why are fluoropolymers flame retardant?
Unlike hydrocarbon-based materials where hydrogen is bonded to oxygen, fluorine-based materials are less likely to combust due to fluorine, which is difficult to bond with oxygen when it comes out.
In addition, in the fluorine material, the CC bond formed by-CF 2-is stronger than the CC bond of-CH 2-, so it can resist attacks and try to destroy the CC bond to make it difficult to burn.
Flame Retardant Polymers and Additives
In sensitive applications, the flame and smoke in the combustion process are as important as the plastic material in standard operation. DAIKIN supports binding safety regulations by proposing solutions and expertise in the field of flame retardancy.
DAIKIN fluoropolymer has excellent flame retardant, smoke and heat resistance properties. It is naturally realized through its chemical structure without additives.
Rated V-0 to UL 94 when the flame source is out, POLYFLON PTFE and NEOFLON FEP or ETFE are less likely to burn and self-extinguish. NEOFLON fluoropolymers are the most suitable solution for the construction of pressure ventilation systems, where high mechanical strength and abrasion resistance also help to maintain good cable insulation.

Reduce flame retardant load in compounds
Optimizing the flame retardant loading is a challenge for composites. To reach this limit, DAIKIN developed Polyflon MPA, a PTFE-based anti-drip polymer modifier. PC,ABS,PS and other resins have limited content, which can prevent dripping during combustion and help to achieve V-0 in UL-94 tests. Polyflon MPA helps Dankai reduce the flame retardant load, thereby optimizing the cost of the formulation. MPA also has excellent storage stability and handling properties. Because of its good dispersibility in the resin, it does not impair the appearance of the molded product.
