Fire-retardant mechanism:

• When heated: FR35RP 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: 

• FR35RP 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, because it does contain polybrominated biphenyl, polybrominated diphenyl ethers, chlorine, fluorine, antimony trioxide and other halogen flame retardants.
• FR35RP is wildly used in rubber goods with fire retardant requirements made of EPDM ,NBR,HCR,NR,SBR,CR IIR,ACM etc.

Key benefits:

• 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.

Common-usage Level: Its general usage is from 60 to 110phr according to different hardness, physical properties, grade of flame retardant, processing, etc. Generally adding 6-8 Phr will increase one degree of hardness; adding 3-5phr will increase one unit of oxygen index.

 

Packaging：25 KG/ Bag, 1000 KG/Pallet.
