FR76RP

Fire-retardant mechanism:

Ø   When heated: FR76RP breaks down on the surface of the product to producea thick coating barrier that isolates oxygen, heat and small molecule diffusionduring combustion. In addition, decomposition of free radicals and H· and OH·reactions to promote combustion terminate the chain reaction of combustion, andrelease water and carbon dioxide at the same time, and effectively absorb alarge amount of heat generated, play a role in flame suppression, so as toachieve the purpose of efficient flame retardant.              

Applications:

Ø   FR76RP is wildly used for mechanical rubber goods with smooth surfaceand relatively low specific gravity which are required to meet not only V0 classfire-retardant grade but also Rohs & WEEE regulation.

Ø   FR76RP is wildly used in rubber goods with fire retardant requirementsmade of EPDM ,NBR,HCR,NR,SBR,CR IIR,ACM etc.

Ø   FR76RP is wildly used in fire retardant rubber and plastic parts, suchas railway transportation parts, electronic parts, automobile, oil and coalmining parts and so on. It is in line with EU RoHS and WEEE regulation, becauseit does contain polybrominated biphenyl, polybrominated diphenyl ethers,chlorine, fluorine, antimony trioxide and other halogen flame retardants.

Key benefits:

Ø   Efficient synergetic flame retardant, easily to reach V0 grade.

Ø   Good dispersibility in the compound.

Ø   Good fluidity of compound with stable size, easy to extrude.

Ø   Low energy consumption during mixing, shorten thecuring time.

Ø   Sheet structure with surface treatment.

Ø   High BET and purity with reasonable and small particle distribution

Ø   Excellent chemical stability, Non-toxic and odorless, halogen-free.

Typical properties：

Common-usage Level: Its general usageis from 60 to 130phr according to different hardness, physical properties,grade of flame retardant, processing, etc. Generally adding 6-8 Phr will increase onedegree of hardness; adding 3-5phr will increase one unit of oxygen index.
