Blowing Agent
OBSH Blowing Agent is an excellent colorless, non-toxic, odorless, pollution-free chemical environmental protection blowing agent, known as universal blowing agent. After foaming, the cell structure is fine and uniform, and it is widely used, and it can also play the role of crosslinking agent.
Product Description
OBSH blowing agent is a chemical foaming agent widely used in rubber and plastic processing. During heating, it decomposes and releases gas to create a cellular foam structure inside the material. Because of its odorless and non-toxic characteristics, OBSH is often selected for applications that require cleaner foaming performance and better finished product quality.
OBSH is also known as a universal blowing agent because it can be used in a wide range of rubber, plastic and synthetic material systems. In some applications, it can also provide a crosslinking effect, helping improve the structure and stability of foamed products.

Shitong OBSH Blowing Agent offers clean processing performance and is suitable for products that require low odor, stable quality and environmental-friendly foaming performance.
The product helps create fine, dense and uniform cells, improving foam appearance, product consistency and overall performance.
With suitable decomposition temperature and controlled gas evolution, OBSH blowing agent supports stable foaming during rubber and plastic processing.
OBSH blowing agent can be used for rubber, PVC, synthetic leather, plastic foam materials and other foamed products.
In certain formulations, OBSH can also help provide a crosslinking effect, supporting better foam structure and product stability.
OBSH blowing agent is suitable for natural rubber, synthetic rubber and rubber-plastic foam products. It helps create fine cells and stable foam structures for rubber components, sealing materials, cushioning products and molded rubber goods.
For PVC foamed products, OBSH can help improve cell uniformity, foam stability and product appearance. It can be used in PVC foam materials, profiles, sheets and other PVC applications.
OBSH blowing agent is suitable for synthetic leather and coated material applications where fine foam texture, low odor and stable surface performance are required.
The OBSH Blowing Agent can be used in various plastic foaming systems to improve foam consistency, reduce defects and support stable production.
AC or ADC blowing agent is commonly used when high gas generation is required. It can form fine cells, but in some formulations it may generate stronger decomposition reaction and require more careful process control.
OBSH blowing agent is often selected for applications that require odorless performance, cleaner processing and fine uniform cells. It is especially suitable for rubber, synthetic leather and plastic foam products where low odor and stable foam quality are important.
When selecting OBSH blowing agent, buyers should consider processing temperature, material system, product thickness, required foam density, cell structure and final application.
For rubber products, the compatibility with rubber compound and vulcanization process should be considered. For PVC and plastic products, the processing temperature, formulation balance and expected foam structure are key factors.
Shitong can recommend suitable blowing agent solutions according to your production process, material system and product performance requirements.Request OBSH Blowing Agent Recommendation
OBSH blowing agent is used for rubber, plastic, PVC and synthetic leather foaming applications. It helps generate gas during processing and form fine, uniform foam cells.
Yes. OBSH blowing agent is widely used in rubber foaming products because it supports fine cell formation, stable foaming and low-odor processing.
The main advantages include odorless performance, non-toxic characteristics, fine and uniform cell structure, stable gas release and wide material compatibility.
AC blowing agent usually provides higher gas generation, while OBSH blowing agent is often preferred for low-odor, cleaner and more stable foaming applications, especially in rubber and synthetic leather products.
