2,3-Dimethyl-2,3-Diphenylbutane（DMDPB）CAS 1889-67-4

2,3-Dimethyl-2,3-diphenylbutane (DMDPB) is a white or pale yellow powdery organic compound, CAS number 1889-67-4, with a molecular weight of 238.37. It is commonly used as a flame retardant synergist and free radical initiator in polymer materials, improving the flame retardant properties and physical and mechanical properties of plastics.

Product Advantage

• Flame Retardant Synergistic Effect: In brominated flame retardant systems, it can replace antimony trioxide (Sb₂O₃) to improve flame retardant performance.

  It significantly reduces the overall amount of flame retardant added, avoiding the negative impact of excessive addition on the material's intrinsic properties.

• Improved Material Properties: While reducing the amount of flame retardant used, it maintains and improves the physical and mechanical properties of plastics.

  It improves the thermal stability and processability of polymers.

• Multifunctional Applications: As a carbon-based initiator, it is more stable than traditional initiators.

  It can be used for crosslinking and graft copolymerization of polymers, as a catalyst or initiator.

• Wide Applicability: Suitable for flame retardant modification of various polymer materials such as polyolefins, polyacrylates, polycarbonates, and polyethers.

• Green and Environmentally Friendly: In some systems, it supports the reduction of halogenated flame retardant usage, moving towards a more environmentally friendly approach.

Technical Parameters

Product Uses

• Flame Retardant Additives/Synthetic Agents: In halogenated flame retardant systems, they act as synergistic additives to improve flame retardancy and reduce the amount of flame retardant required.

  They can partially replace antimony trioxide, improving the mechanical strength and thermal stability of materials.

  They can be used for flame retardant modification of plastics such as polypropylene and polystyrene, significantly improving the oxygen index and flame extinguishing time.

• Polymer Crosslinking and Grafting: As catalysts or initiators, they are used in the crosslinking or graft copolymerization of polymers (such as polyolefins and polyacrylates).

• Used for initiating and grafting high-energy plastics.

  Other Polymer Material Modification: Used for the modification of various engineering plastics such as polycarbonate and polyether.

Product Operate Guide

• In flame retardant masterbatches, the recommended addition level is 2-3%.

• In polymer modification, the recommended addition level is 0.2-0.5%.

• It has higher thermal stability than general free radical initiators.

• It can be used as a non-peroxide initiator.
