Jiangsu Suoteng Offers Dicumene as a Non-toxic, Synergistic Flame Retardant

Jiangsu Suoteng offers Dicumene (DMDBP), a non-hazardous, carbon-based initiator with excellent performance. It is mainly used for polymer cross-linking or grafting reactions at higher temperatures. 


Solution for Halogen-antimony Systems and Halogen-free Alternatives:

In recent years, the flame retardant industry has seen growing demand for dicumene. It is known for its high stability, safe use, and good environmental performance.

Dicumene is primarily used as an initiator, grafting agent, and flame retardant synergist in engineering plastics, flame retardant polyolefins, and other applications.


As environmental regulations become stricter, traditional flame retardants are facing restrictions due to low efficiency, large dosages, and environmental concerns. This has led to a shift toward greener, more efficient, and low-toxicity flame retardants.


Dicumene, as one of the earliest free radical initiators used as a flame retardant synergist, fits well with this trend. Its non-toxic, smoke-suppressing, and cost-effective properties are attracting increasing market interest.


It is widely used in flame retardant polystyrene, polypropylene, brominated and phosphorus flame retardants, bromine-phosphorus composite flame retardants, and engineering plastics. In the halogen-antimony flame retardant system, dicumene reduces the amount of halogen flame retardants and antimony trioxide, which lowers costs, enhances polymer performance, suppresses smoke, reduces toxicity, and improves flame retardancy and mechanical properties of plastics.


Dicumene also serves as a synergist in flame retardancy for polyolefin plastics, replacing antimony trioxide in bromine systems to boost flame retardancy and improve plastic properties. It is used as a grafting catalyst for polystyrene and polypropylene and as a polymer cross-linking initiator.


2,3-Dimethyl-2,3-Diphenylbutane (DMDPB) is versatile in plastic applications and works as a synergistic flame retardant in both bromine-antimony and halogen-free systems. Its high heat resistance makes it suitable for engineering plastics requiring higher processing temperatures. Dicumene is a popular, low-cost, non-toxic, and smoke-suppressing flame retardant.


Product Applications

Flame Retardant Enhancement: Used in polymers like PP, EPS, HIPS, XPS, ABS, etc. In halogen-antimony systems, it reduces halogen flame retardant and antimony trioxide usage, suppresses smoke, cuts toxicity, lowers costs, and improves polymer properties. It also enhances flame retardancy in halogen-free systems.

Minimal Impact on Tensile Strength: Adding 0.1%-0.2% to the system has minimal impact on tensile strength while enhancing flame retardant properties. This reduces the overall flame retardant usage by 15%-30%, offering a cost-effective solution.

Today's KNOWLEDGE Share : Researchers Create Deployable Silk Fibers for Adhering and Lifting Objects

Today's KNOWLEDGE Share The stream of liquid silk quickly turns to a strong fiber that sticks to and lifts objects These sticky fibers, created at the Tufts University Silklab, come from silk moth cocoons, which are boiled in solution and broken down into their building block proteins called fibroin.The silk fibroin solution can be extruded through narrow bore needles to form a stream that, with the right additives, solidifies into a fiber when exposed to air.  Nature is the original inspiration for deploying fibers of silk into tethers, webs, and cocoons. Spiders, ants, wasps, bees, butterflies, moths, beetles, and even flies can produce silk at some point in their lifecycle.Nature also inspired the Silklab to pioneer the use of silk fibroin to make powerful glues that can work underwater, printable sensors that can be applied to virtually any surface, edible coatings that can extend the shelf life of produce,a light collecting material...

Today's KNOWLEDGE Share : biobased content of polycarbonate diols

Today's KNOWLEDGE Share MCG increases biomass content of polycarbonate diols Mitsubishi Chemical Group (MCG) has introduced grades of its Benebiol biomass-based polycarbonate diols that have a higher biomass content. The product is primarily used in the manufacture of polyurethane resins for coatings in sectors such as automotive, furniture and outdoor products. It is also used in the production of artificial leather. Existing Benebiol grades had a bio-based content of 20-50%, but the new HSS and NLDS grades have a biomass content in excess of 80%. Some of its previous petroleum-derived grades have also been converted to biomass, as the NLS grades. This, the company said, allows it to offer bio-based grades of all its Benebiol products. The shift to biomass-based raw materials while maintaining high-quality functions will contribute to our customers’ efforts to achieve sustainable manufacturing. source:MCG/www.utech-polyurethane.com
