Brief Introduction
TBPO is a colorless transparent liquid and an ester organic peroxide. It is widely used in polyolefin polymerization initiators, methacrylate and propylene monomer polymerization initiators, as well as rubber and paint industries.
The main uses are
1. This product is a commonly used polymerization initiator for ethylene polymerization, which is suitable for kettle and tube processes. It is also the polymerization initiator of acrylate and methacrylate, and the applicable temperature range is 80-150 ℃.
2. This product can be used for polymerization initiation of polystyrene, and its activity is better than BPO. It can also be used in combination with peroxides such as TBPB and TBEC. It is also an important initiator of vinyl acetate (EVA) co-polymer.
3. It is a high-temperature curing agent for unsaturated polyester. The curing temperature is 120-160 ℃. It is preferred to be used in hot pressing molding curing process (DMC, BMC). It can also act with cobalt accelerators. It can be used in air drying paint and winding molding process at 60 ℃.
