Description

Oxybisbenzenedisulphonylhydrazide is an organic chemical compound widely recognized as a high-performance blowing agent. This product matters for its ability to generate a high volume of gas upon decomposition, making it essential for creating uniform, fine-celled cellular structures in various polymer matrices. Industries such as plastics, rubber, and polymer manufacturing rely on this compound to produce lightweight, insulating, and resilient foamed products with consistent quality.

Application

• Primary blowing agent for the production of expanded PVC (polyvinyl chloride) foams, including flooring and synthetic leather.
• Key component in the foaming of ethylene-vinyl acetate (EVA) copolymers for applications in sports equipment, shoe soles, and packaging materials.
• Used in the manufacture of cross-linked polyethylene (XLPE) foam for insulation and cushioning.
• Employed in the rubber industry for producing sponge rubber and microcellular elastomers.
• Facilitates the creation of low-density polyolefin foams with excellent thermal and acoustic insulation properties.
• Applicable in specialty polymer formulations requiring a high gas yield and controlled decomposition temperature.

Quality Control

Our Oxybisbenzenedisulphonylhydrazide is manufactured under strict quality protocols to ensure batch-to-batch consistency and performance reliability. Each lot undergoes rigorous analytical testing, including assay, decomposition temperature, and gas yield analysis. A comprehensive Certificate of Analysis (COA) detailing purity, moisture content, and particle size distribution is provided with every shipment to guarantee compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from heat, sparks, and open flame.
