Description

Lauroyl Peroxide is a highly effective organic peroxide widely recognized for its role as a polymerization initiator and cross-linking agent. Its controlled decomposition properties are critical for initiating free-radical reactions in the production of polymers and resins. This compound is essential for manufacturers in the plastics, rubber, and coatings industries seeking reliable and efficient process chemistry. We supply high-purity Lauroyl Peroxide CAS NO 105-74-8 to meet the stringent demands of global industrial applications.

Application

• Polymerization Initiator: Primarily used for the free-radical polymerization of vinyl monomers such as styrene, vinyl chloride, and acrylates in the production of plastics and resins.
• Cross-linking Agent: Employed in the vulcanization and curing of silicone rubbers and certain polyethylene compounds to enhance thermal and mechanical properties.
• Unsaturated Polyester Resin Curing: A key component in the curing (hardening) of fiberglass-reinforced plastics (FRP) and composite materials.
• Acrylic Polymer Production: Initiates the polymerization reaction in the manufacture of acrylic sheets, molding powders, and surface coatings.
• Flame Retardant Synergist: Used in combination with other compounds in specific polymer formulations to improve flame-retardant characteristics.
• Chemical Synthesis Intermediate: Serves as an oxidizing agent or radical source in specialized organic synthesis processes.

Quality Control

Our Lauroyl Peroxide is manufactured under strict quality management systems to ensure batch-to-batch consistency and reliability. The product undergoes comprehensive analytical testing, including assay, purity profiling, and impurity screening. A Certificate of Analysis (COA) detailing all test results is provided with each shipment. Our quality commitment aligns with industrial standards for polymerization initiators, ensuring optimal performance in your processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat, sparks, and open flames. Due to its nature as an organic peroxide and being easily oxidized (store under inert atmosphere), it should be kept separate from reducing agents, acids, bases, and other combustible materials. Recommended storage temperature is below 30°C (86°F).
