Usage
Application | Details |
---|---|
Polymer Crosslinking Agent | Suitable for crosslinking of various polymers, especially polyethylene (LDPE, HDPE) and ethylene/vinyl acetate copolymers. Crosslinking temperature >170°C, no crosslinking below 140°C. Dosage: 0.5-3% (W/W), higher for materials that are hard to crosslink. |
High-Temperature Vulcanizing Agent for Silicone Rubber | Ideal for vulcanizing silicone rubber, as well as other rubber types, providing high tensile strength and hardness. |
Polypropylene Degradation Agent | Effective for polypropylene degradation, creating low molecular weight, narrow molecular distribution polypropylene. Used in production of fibers, coatings, films, and cast materials. |
High-Temperature Curing Agent for Unsaturated Polyester | Widely used for curing unsaturated polyester resins. |

Disposal Methods
Disposal Method | Description |
---|---|
Diluted Incineration | Dilute the product with inexpensive solvents (e.g., alcohol) to less than 10%, and incinerate under controlled conditions. |
Hydrolysis | Use a solution of caustic soda in methanol or isopropanol (20%-30%) to hydrolyze, adding the product to 10 times its weight of caustic solution, stirring until complete hydrolysis. |
Large-Scale Disposal | For large quantities, notify the manufacturer for specialized disposal handling. |
Spill Handling
Spill Handling | Description |
---|---|
Eye Contact | Flush eyes with water for 15 minutes, seek medical attention. |
Skin Contact | Wash thoroughly with soap and water, seek medical attention. |
Spill on Ground | Absorb with inert materials (sand, vermiculite), then collect with non-sparking tools and dispose of properly. |
Fire Protection
Fire Protection | Description |
