Fire-retardant mechanism:

• When heated: FR98RP breaks down on the surface of the product to produce a thick coating barrier that isolates oxygen, heat and small molecule diffusion during combustion. In addition, decomposition of free radicals and H· and OH· reactions to promote combustion terminate the chain reaction of combustion, and release water and carbon dioxide at the same time, and effectively absorb a large amount of heat generated, play a role in flame suppression, so as to achieve the purpose of efficient flame retardant.

Applications: 

• FR98RP is wildly used for mechanical rubber&plastic goods with smooth surface and relatively low specific gravity which are required to meet not only V0 class fire-retardant grade but also RoHS& WEEE
• FR98RP is wildly used in rubber goods with fire retardant requirements made of EPDM ,NBR,HCR,NR,SBR,CR IIR,ACM etc.
• FR98RP iswildly used in fire retardant rubber and plastic parts, such as railway transportation parts, electronic parts, automobile, oil and coal mining parts and so on. It is in line with EU RoHS and WEEE regulation, because it does contain polybrominated biphenyl, polybrominated diphenyl ethers, chlorine, fluorine, antimony trioxide and other halogen flame retardants.

Key benefits:

• Efficient synergetic flame retardant, easily to reach V0 grade.
• Good dispersibility in the compound.
• Good fluidity of compound with stable size, easy to extrude.
• Low energy consumption during mixing, shorten the curing time.
• Sheet structure with surface treatment.
• High BET and purity with reasonable and small particle distribution
• Excellent chemical stability, Non-toxic and odorless, halogen-free.
