4-Methylbenzenesulfonhydrazide serves as an indispensable, high-efficiency chemical blowing agent, multifunctional organic synthetic reagent, and versatile reactive intermediate extensively utilized across polymer foam compounding, rubber manufacturing, pharmaceutical chemistry, and fine organic synthesis. In polymer materials processing and elastomer technology, widely recognized as blowing agent TSH, it functions as a premier low-temperature chemical foaming agent characterized by a narrow decomposition temperature range and steady gas release kinetics; upon thermal decomposition, it generates non-toxic nitrogen gas and water vapor without emitting corrosive byproducts or imparting discoloration to matrix materials, making it a golden standard additive in processing natural rubber, neoprene, ethylene-vinyl acetate (EVA), polyvinyl chloride (PVC), and epoxy resins to produce microcellular shoe soles, automotive sealing profiles, acoustic insulation foams, and lightweight elastomeric cushions featuring uniform pore distribution and superior resilience. In organic chemistry and active pharmaceutical ingredient (API) development, 4-Methylbenzenesulfonhydrazide is a cornerstone synthetic tool that readily condenses with aldehydes and ketones to generate sulfonylhydrazone intermediates for executing classic Shapiro alkenylation, Bamford-Stevens transformations, and Eschenmoser-Tanabe fragmentations to construct complex carbocyclic and polycyclic architectures; furthermore, it serves as a mild, metal-free precursor for generating diimide in situ to achieve chemoselective reduction of unsaturated carbon-carbon double and triple bonds in sensitive drug intermediates and crop protection chemicals.

规格 / Specification

Applications:

4-Methylbenzenesulfonhydrazide is used as a foaming agent for natural rubber, synthetic rubber and various plastics and in organic synthesis.

1: 4-Methylbenzenesulfonhydrazide is used as a foaming agent for rubber and various plastics. Mixing with ADC foaming agent and baking soda can promote ADC foaming agent to increase gas emission. 4-Methylbenzenesulfonhydrazide is used as a foaming agent for natural rubber, synthetic rubber and various plastics to produce fine closed-cell structures for plastics and rubber products. The shrinkage rate of the products is small and the tear strength is large. It is used as a foaming agent for natural rubber, synthetic rubber and various plastics and in organic synthesis.

2: 4-Methylbenzenesulfonhydrazide is a low-temperature foaming agent, suitable for various plastics and rubbers such as natural rubber, synthetic rubber and polyvinyl chloride. The generated gas and decomposition residue are non-toxic, odorless and non-polluting. The product has a uniform and fine pore structure, a small shrinkage rate and a large fracture strength. It is particularly suitable for the manufacture of closed-cell foam plastics and sponge rubber. This product has a low decomposition temperature and should be mixed below 70°C. 4-Methylbenzenesulfonhydrazide cannot be used together with dinitrosopentamethyltetramine (foaming agent H) or lead salts to avoid coking and contamination of the rubber. No foaming aid is required when using 4-Methylbenzenesulfonhydrazide.

3: 4-Methylbenzenesulfonhydrazide is a foaming agent with extremely wide adaptability and is known as a universal foaming agent. It has a low decomposition temperature and can be mixed below 70°C. It is suitable for various plastics, natural and synthetic rubbers. The generated gas and decomposition residues are non-toxic, odorless, and pollution-free. The pore structure is fine and uniform, the product shrinkage is small, and the tear strength is high. It is especially suitable for the manufacture of closed-cell foam plastics and sponge rubber. It can be used in polyvinyl chloride to produce white foam (the mold needs to be chrome-plated). It cannot be used together with foaming agent H and lead salts, and generally no foaming aid is required.
