Purpose:

1. Polymer cross-linking agent: It is an organic peroxide cross-linking agent that can be widely used in various polymers, especially for polyethylene (LDPE, HDPE) and ethylene/vinyl acetate copolymers. The cross-linking temperature is above 170 ℃, and no cross-linking occurs below 140 ℃. The dosage is 0.5% -3% (W/W), which is generally 1% -5% in some materials that are not prone to crosslinking.

2. It is a high-temperature vulcanizing agent for vinyl silicone rubber: it is also an excellent vulcanizing agent for other types of rubber. Rubber vulcanized with this product has outstanding advantages such as high tensile strength and high hardness.

3. It is an excellent degradation agent for polypropylene: the degradation temperature is 200-220 ℃, and the dosage is 0.01-0.1%. It can be made into rheological polypropylene with low molecular weight and narrow molecular weight distribution, and high melt index. It can be used as an important initiator for high-speed spinning materials, coating materials, film materials, and casting plastics, and is the preferred raw material for producing cooling masterbatches.

4. It is a high-temperature curing agent for unsaturated polyester.

Destruction method:

1. Dilution incineration: Dilute the products to be destroyed with inexpensive solvents such as sprinkling, waste oil, etc. to less than 10% and then incinerate them under controlled conditions.

2. Hydrolysis: Prepare a methanol or isopropanol solution of caustic soda at a rate of 20% -30%, and then add the product to be destroyed to a caustic soda solution about 10 times its weight, stirring while adding until the hydrolysis is complete.

3. Users must notify the manufacturer to send specialized personnel to handle the destruction of a large number of products to avoid accidents.

Splash treatment:

1. If the product enters the eye by mistake, the eyelids should be immediately opened and rinsed with flowing water for 15 minutes before seeking medical attention.

2. If accidentally splashed onto the skin, immediately rinse thoroughly with soap and water. Seek medical attention.

3. If the product splashes or leaks onto the ground, it should be absorbed by sand, vermiculite, or other inert materials, and then collected in plastic drums with non sparking tools, and transported to a waste disposal site. And rinse the contaminated ground with water.

Fire protection:

1. This product may decompose violently due to heating, and may ignite violently. A small amount of small fires should be put out quickly with foam or dry powder extinguishers.

2. The fire should be quickly evacuated to a safe distance and extinguished with a water gun, and the fire department should be notified for handling.
