Chemical name: Di-tert-butyl peroxide
Another name: Di-tert-butyl peroxide, initiator A, DTBP
CAS No.: 110-05-4
Molecular formula: C8H18O2
Molecular-weight: 146.2
Application
1. As polymerization initiator of vinyl and dienyl monomers, the recommended cross-linking temperature range is 180-240 ℃. It is a common initiator in the high-pressure polyethylene polymerization process of Kan method and kettle method, and the cross-linking temperature range is 240-280 ℃.
2. It is a high temperature curing agent for unsaturated polyester.
3. It is a vulcanizing agent of diene rubber, which is suitable for vulcanization of thick rubber products. It has good tensile strength, elongation, compression and permanent deformation resistance. It has been approved by FDA. It is suitable for the vulcanization of most rubber, polyurethane elastomer and silicone rubber. It can obtain white and various bright colored rubber products.
4. Used in polypropylene high-speed spinning (polypropylene fiber) industry as molecular weight regulator (used in cooling master-batch production). It has the characteristics of narrow molecular weight distribution, high melt index and uniform spinning. It is an excellent degradation agent used in polypropylene modification. Adding this product to polypropylene can make controlled rheological polypropylene, improve fluidity, make rapid molding of polypropylene possible, and reduce the deformation caused by molding. The modified polypropylene can be made into film material.
5. It is used for oil additives and pour point depressant of transformer oil.
