Diphenylsulfone hydrazide is a high-performance chemical commonly used as a blowing agent in specialized engineering polymers. Its production is more niche compared to other sulfonyl hydrazides, owing to its higher cost and complex manufacturing routes. In recent years, production trends have been relatively steady but constrained by limited demand in niche markets, primarily focused on high-performance foamed polymers in aerospace, electronics, and premium automotive interiors. On the pricing side, diphenylsulfone hydrazide has traditionally commanded a premium due to its specialty applications and higher production costs. Price trends over the past year have shown moderate upward movement, in line with rising raw material prices for diphenyl sulfone and hydrazine derivatives. Furthermore, energy price spikes and stricter global shipping regulations have added upward pressure. Looking into 2025, prices are expected to remain firm, as demand for premium foamed materials continues to rise in high-tech industries and supply remains relatively tight.
