4,4'-Oxybis(Benzenesulfonyl Hydrazide) (OBSH)
4,4'-Oxybis(Benzenesulfonyl Hydrazide) (OBSH) is a sulfonate-type chemical blowing agent used to generate cellular structures in rubber and plastics processing. This product from Heze Kingvolt Chemical Co., Ltd. has a CAS number of 80-51-3 and a molecular formula of C12H14O5N4S2, delivering thermal stability and controlled decomposition ideal for EPDM, silicone rubber, and PVC applications. The compound produces odourless, tasteless foam with uniform stomatal structure, making it suitable for light-coloured and low-odour applications.
OBSH appears as a white powder with a minimum purity of 98% and maximum water content of 0.5%. It decomposes between 152-162°C at a heating rate of 5°C/min in air, releasing approximately 125 ml/g of gas. Standard industry use includes natural and synthetic rubbers such as EPDM, SBR, CR, FKM, IIR, and NBR, as well as thermoplastics like PVC, PE, PS, and ABS. Its versatility extends to wire and cable applications due to fine insulativity, and it can function as both a blowing agent and a crosslinking agent in curing mechanisms.
Manufacturers of extruded profiles, molded rubber parts, and foam insulation rely on OBSH for automotive, construction, and footwear export markets. The compound is often combined with other blowing agents to achieve tailored foaming characteristics. Buyers should confirm decomposition temperature compatibility with their processing conditions and verify gas volume output for consistency with their formulation requirements.

Sourcing 4,4'-Oxybis(Benzenesulfonyl Hydrazide) (OBSH) from Heze Kingvolt Chemical Co., Ltd. - China Import Guide
Before ordering, verify the decomposition temperature range and gas volume output align with your processing conditions. Confirm the OBSH grade’s compatibility with your polymer matrix, as variations in molecular weight or additives can affect performance. Request a certificate of analysis (COA) to validate purity, water content, and other critical specifications.
Logistics details such as lead time, Incoterms (e.g., FOB or CIF), and packaging type (e.g., 25 kg bags) should be confirmed directly with Heze Kingvolt Chemical Co., Ltd. Ensure the supplier can meet your MOQ and has experience exporting to your region. Port of loading will typically be a major Chinese port such as Shanghai or Qingdao.
For quality assurance, conduct incoming inspections for appearance, particle size, and moisture content. During production, monitor foaming consistency and cross-link density. Request documentation such as SDS (Safety Data Sheet) and COA for compliance with your internal standards and regulatory requirements in your market.
