Properties and uses of DTBP- di-tert-butyl peroxide

Property：
This product is a slightly yellow transparent liquid, which can be diluted with the solvent specified by the customer. Insoluble in water, soluble in most organic solvents, flash point: 12.5 ℃ (closed dish), 18 ℃ (open dish), boiling point: 109 ℃, freezing point: -40 ℃. Viscosity (20 ℃): 0.9mPa. s.

Purpose:

1. As a polymerization initiator for vinyl and dienyl monomers, the recommended crosslinking temperature range is 180-240 ℃. It is a commonly used initiator in high-pressure polyethylene polymerization processes using the Kan method and the kettle method, with a crosslinking temperature range of 240-280 ℃.

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

3. It is a vulcanizing agent for diene rubber, suitable for vulcanizing thick rubber products. Good tensile strength, elongation, compression and permanent deformation resistance, approved by FDA, suitable for vulcanization of the vast majority of rubber, polyurethane elastomers, and silicone rubber. It can obtain white and various bright colored rubber products.

4. Used in the high-speed spinning of polypropylene (polypropylene fiber) industry as a molecular weight regulator (used in the production of cooling masterbatch). It has the characteristics of narrow molecular weight distribution, high melt index, and uniform spinning, and is an excellent degradation agent used in polypropylene modification. By adding this product to polypropylene, it can be made into controlled rheological polypropylene, improve flowability, and make rapid molding of polypropylene possible, while reducing deformation caused by molding. Modified polypropylene can be made into thin film materials.

5. Used as oil additive and pour point depressant of transformer oil.
