Description

2,2-Di(tert-Butylperoxy)Butane is a high-purity organic peroxide widely used as a free-radical initiator and crosslinking agent. Its controlled decomposition characteristics make it essential for initiating polymerization reactions and modifying polymer properties. This compound is a critical raw material for manufacturers in the polymer, rubber, and specialty plastics industries seeking to optimize production efficiency and material performance.

Application

• Polymerization Initiator: Used as a free-radical source for the production of polyethylene (LDPE), polystyrene, and other vinyl polymers.
• Crosslinking Agent: Employed in the vulcanization and curing of elastomers and silicone rubbers to enhance thermal and mechanical properties.
• Unsaturated Polyester Resin Curing: Acts as a catalyst for the curing of fiberglass-reinforced plastics (FRP) and sheet molding compounds (SMC).
• Chemical Synthesis: Serves as an intermediate or oxidizing agent in the synthesis of specialty organic compounds and pharmaceuticals.
• Adhesive & Coating Formulations: Utilized in formulations requiring controlled, low-temperature cure initiation for high-performance adhesives and coatings.

Quality Control

Our production of 2,2-Di(tert-Butylperoxy)Butane adheres to stringent quality management systems. Every batch is analyzed to ensure high purity and consistent performance as a polymerization initiator. Certificates of Analysis (COA) detailing assay, active oxygen content, and impurity profiles are provided and traceable to in-house standards. We support compliance with relevant global chemical regulations, including REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Keep away from reducing agents, strong acids, bases, and other incompatible materials. Recommended storage temperature is below 30°C (86°F). This product is a strong oxidizer and light-sensitive (store away from light); appropriate safety protocols for handling organic peroxides must be observed.
