Acyl Peroxides
Acyl peroxides are known for their strong oxidative properties, making them useful in a variety of industrial applications. They are commonly used as polymerization initiators, curing agents, and cross-linking agents, playing a vital role in processes that require the stabilization and transformation of materials, particularly in plastics and rubber manufacturing.
Acyl Peroxides
-
Inquiry - Dibenzoyl peroxide (BPO)
CAS 94-36-0
- Molecular Formula: C₁₄H₁₀O₄
- Molecular Weight: 242.2
- UN No.: 3104
-
- This compound is one of the most commonly used radical initiators, frequently applied in the polymerization of acrylates. It works as an initiator for styrene and styrene copolymers and is often combined with other initiators like tert-butyl peroxybenzoate (LQ-TBPB) for enhanced performance.
-
Inquiry - Bis(3,5,5-trimethylhexanoyl) peroxide (K)
CAS 3851-87-4
- Molecular Formula: C₁₈H₃₄O₄
- Molecular Weight: 314.5
- UN No.: 3115
-
- This chemical compound is widely used as a polymerization initiator for ethylene, particularly in the production of LDPE through tubular or autoclave processes. It is often combined with other initiators to achieve a broader range of polymerization temperatures, typically between 150°C and 190°C.
-
Inquiry - Diisobutyryl peroxide (DIPB)
CAS 3437-84-1
- Molecular Formula: C₈H₁₄O₄
- Molecular Weight: 174.2
- UN No.: 3115
-
- This chemical compound is commonly used as a radical initiator in polymerization reactions. It also serves as a curing agent for polyesters, a cross-linking agent for rubber, and is used as a foaming agent, bleaching agent, and drying agent in various industrial applications.
-
Inquiry - Bis(2,4-dichlorobenzoyl)peroxide (CBPO)
CAS 133-14-2
- Molecular Formula: C₁₄H₆O₄Cl₄
- Molecular Weight: 380.0
- UN No.: 3106
-
- Works as an excellent vulcanizing agent for silicone rubber, providing safe handling at 75°C and a vulcanization temperature of 90°C. The recommended dosage ranges between 1.1% and 2.3%. Beyond its use in the rubber industry, CBPO is also in the manufacturing of low-voltage power cable rubber materials and composite rubbers.
-
Inquiry - Dilauroyl peroxide (LPO)
CAS 105-74-8
- Molecular Formula: C₂₄H₄₆O₄
- Molecular Weight: 398.6
- UN No.: 3106
-
- LPO is frequently used in polymerization processes, with a working temperature range between 60°C and 75°C. In many cases, it is combined with higher reactivity peroxides, such as Bis(4-tert-butylcyclohexyl) peroxydicarbonate or tert-butyl peroxyneodecanoate (1,1,3,3-tetramethylbutyl ester), to broaden its reactivity range and improve efficiency.
