Description

p-Toluenesulfonyl Semicarbazide is a specialized organic compound belonging to the class of sulfonyl hydrazides, widely recognized for its utility as a high-performance chemical blowing agent. This compound matters to manufacturers because it offers a clean decomposition profile, generating nitrogen gas as the primary blowing agent without leaving undesirable residues, which is critical for producing fine-celled, high-quality foams. Industries that need this product include polymer and plastics manufacturing, particularly for applications requiring precise foaming control in engineering plastics, synthetic leather, and rubber products.

Application

• Chemical Foaming Agent (CFA): Primary use as a nitrogen-based blowing agent for the production of expanded plastics and elastomers, including PVC, EVA, polyethylene, and polypropylene.
• Microcellular Foam Production: Enables the manufacture of lightweight, fine-celled foams with uniform cell structure for automotive interior parts, insulation materials, and sports equipment.
• Synthetic Leather & Artificial Leather: Used in the formulation of expandable layers to create a soft, leather-like texture and appearance.
• Rubber Product Manufacturing: Facilitates the production of expanded rubber for seals, gaskets, and vibration-damping components.
• Wire & Cable Insulation: Employed in cross-linked polyethylene (XLPE) and other polymer insulations to improve dielectric properties and reduce material weight.
• Pharmaceutical & Agrochemical Intermediates: Serves as a key building block or reagent in the synthesis of more complex molecules for active pharmaceutical ingredients (APIs) and crop protection agents.
