| Name | Exterior view | Chemical composition | Complex carrier | Characteristics |
|---|---|---|---|---|
| First ZBS-75 |  |
Chemical composition: Zinc phenylsulfinate | Complex carrier: EPDM | Characteristics: Suitable for all types of blowing agents, especially AC, H, and other blowing agents, it lowers the foaming temperature, increases gas yield, enhances the uniformity of foam pore size, and effectively eliminates odors released during the decomposition of H-type blowing agents. It also prevents discoloration and avoids contamination, while ensuring easy dispersion. Commonly used in NR, SBR, EPDM, NBR, and plastic foam products. |
| First PTSS-75 | |
Chemical composition: p-Toluenesulfonamidourea | Complex carrier: EPDM | Characteristics: This product is a high-temperature blowing agent, specifically designed for rubber and plastic products processed at elevated temperatures. It serves as an effective foaming agent for synthetic rubbers such as natural rubber and styrene-butadiene rubber. The product offers excellent processing safety, with no risk of premature foaming. By incorporating certain activators—such as catalysts like BM or TM, or surface-treated urea—you can further reduce the decomposition temperature, making it suitable for low-temperature foaming applications. |
| First AC3000-75 |  |
Chemical composition: Azodicarbonamide | Complex carrier: EPDM | Characteristics: Commonly used general-purpose high-temperature blowing agents, widely applied in the foaming of rubber and plastics such as PE, PS, EVA, PVC, and rubber-plastic foam products. They decompose at temperatures between 200–210°C and deliver a gas yield of 210–225 ml/g. These agents are extensively utilized in rubber sealing strips, sports equipment, insulation materials, and footwear components. |
| AC7000-75 | |
Chemical composition: Azodicarbonamide | Complex carrier: EPDM | Characteristics: Commonly used general-purpose high-temperature blowing agents, widely applied in the foaming of rubber and plastics such as PE, PS, EVA, PVC, and rubber-plastic foam products. They decompose at temperatures between 200–210°C and deliver a gas yield of 210–225 ml/g. These agents are extensively utilized in rubber sealing strips, sports equipment, insulation materials, and footwear components. |
| First OBSH-75 | |
Chemical composition: 4,4-Dioxobis(benzenesulfonhydrazide) | Complex carrier: EPDM | Characteristics: Commonly used organic foaming agents for rubber; suitable for medium- and low-temperature foam-forming processes without accelerators. Decomposition occurs at 158°C, with a gas yield of 93.0–105.0 ml/g. It is easy to weigh, readily dispersible, does not fly during use, leaves no pollution, and maintains its color integrity. |
| First EWE-60 |  |
Chemical composition: Microsphere Physical Blowing Agent | Complex carrier: EPDM/EVM | Characteristics: As a high-end foaming agent used in various synthetic rubber products, it significantly improves the specific gravity of the finished items. Compared to chemical foaming agents, products made with this agent exhibit superior retention of key physical and mechanical properties—such as hardness, tensile strength, tear resistance, and elongation—making it ideal for a wide range of plastic and rubber applications, particularly in window and door sealing strips. These products are lightweight yet deliver outstanding sealing performance. |
