OBSH (p-Toluenesulfonyl hydrazide) is a chemical blowing agent that releases gas upon thermal decomposition, creating a fine foam structure in rubber, plastic, and other materials. OBSH is commonly used in the footwear industry, particularly for producing flexible foams that require controlled expansion. This agent is also used in various rubber and plastic applications where consistent foam quality is needed.

1. What is OBSH (p-Toluenesulfonyl hydrazide)?
OBSH is a chemical blowing agent that decomposes upon heating, releasing nitrogen gas and forming a fine foam structure in rubber, plastic, and footwear products.
2. How does OBSH work as a blowing agent?
OBSH decomposes under heat, releasing nitrogen gas that creates a fine foam structure with uniform cell density in the material.
3. What are the main applications of OBSH?OBSH is primarily used in the footwear and rubber industries to produce flexible foams, and it is also used in plastic foam production for packaging and insulation.
4. Is OBSH safe to use?
When handled and processed according to safety guidelines, OBSH is safe for use in industrial applications such as footwear and rubber foam production.
5. How should OBSH be stored?
OBSH should be stored in a cool, dry place, away from moisture and heat to maintain its effectiveness.
