In-depth analysis of the characteristics and application fields of polymer carbon flame retardant synergist 2,3-dimethyl-2,3-diphenylbutane (DMDBP)

In recent years, with the development of the flame retardant industry, the market demand for dicumene has gradually been released. Senior industry insiders analyzed that dicumene has the characteristics of high stability, safe use, and good environmental performance. It is mainly used as an initiator, grafting agent, flame retardant synergist, etc. in engineering plastics, flame retardant polyolefins and other fields.

Dicumene is in line with the current trend of environmental protection and green consumption. In recent years, with the increasingly stringent environmental supervision, the market application of traditional flame retardants has been restricted due to factors such as low flame retardant efficiency, large dosage, and environmental pollution. Green, high-efficiency, and low-toxic flame retardants have become the main direction of flame retardant market development. Dicumene is one of the earliest free radical initiators used as a flame retardant synergist. With its non-toxic, smoke-suppressing, and low-cost characteristics, it has attracted more and more market attention.

Dicumene (DMDBP) has excellent comprehensive performance, is not a hazardous chemical, and is a carbon-based initiator. It is mainly used for polymer cross-linking or grafting reactions that require higher temperatures. Since the initiator does not contain oxygen, the polymer has strong anti-aging and antioxidant capabilities after processing. Dicumene (DMDBP) is more stable and safe to use than general free radical initiators such as peroxides and azo compounds.
Due to the particularity of the structure, the CC bond between the corresponding carbon atoms is not very stable and is easily dissociated to form free radicals. It is mainly used as a flame retardant synergist and cross-linking copolymerization catalyst. Dicumene has a white powdery appearance. Compared with free radical initiators such as peroxides and azo compounds, Dicumene products have the advantages of high stability, safe use, good environmental performance, and strong antioxidant ability.

Dicumene (DMDBP) can be used as a flame retardant synergist, flame retardant synergist, grafting catalyst, cross-linking initiator, etc. It is used in flame retardant polystyrene, polypropylene, brominated flame retardants, phosphorus flame retardants, bromine-phosphorus composite flame retardants, and engineering plastics.
In the halogen-antimony flame retardant system, Dicumene can reduce the amount of halogen flame retardants and antimony trioxide, play the role of reducing costs and increasing efficiency, improving polymer performance, suppressing smoke and reducing toxicity, increasing flame retardant effect, and increasing the physical and mechanical properties of plastics while reducing the amount of flame retardants.
This product is a synergistic synergist for flame retardancy; it is mainly used as a synergistic synergist for fire retardant of polyolefin plastics. It can replace antimony trioxide in the bromine flame retardant system to increase the flame retardant effect, while reducing the amount of flame retardants, it increases the physical and mechanical properties of plastics; it is used as a grafting catalyst for polystyrene and polypropylene; it is used as a polymer cross-linking initiator.

2,3-Dimethyl-2,3-Diphenylbutane(DMDPB) can be applied to a variety of plastics and can be used as a synergistic flame retardant in both bromine-antimony and halogen-free flame retardant systems. This product has high heat resistance and can be used in engineering plastics with higher processing temperatures. It is a popular additive flame retardant due to its non-toxic, smoke-suppressing and low-cost characteristics.

Product Applications
1. Widely used in flame retardant enhancement of polymer materials such as PP, EPS, HIPS, XPS, ABS, etc.: In the halogen-antimony flame retardant system, it can greatly reduce the dosage of halogen flame retardants and antimony trioxide, suppress smoke, reduce toxicity, reduce costs, and improve the physical properties of polymers; it can also be used as a flame retardant enhancer in halogen-free flame retardant systems;
2. The amount added has little effect on the tensile strength of the polymer system, taking into account both tensile properties and flame retardant properties. Considering the cost factor, it can be determined that the appropriate amount in the system is 0.1%-0.2%, and the overall amount of flame retardant can be reduced by 15%-30%;
3. It is used as a cross-linking initiator and grafting agent for polymers such as PP and PS. It is easy to form free radicals with high stability under certain conditions. It can be used as a free radical initiator for cross-linking copolymerization of polymers to achieve the purpose of improving polymer properties.
