Store Dicumyl Peroxide in a cool, dry and well-ventilated area and in line with legal requirements. Keep Iniper DCP away from heat sources, avoid contact with acids, alkalines, heavy metal compounds and reducing agents. The Self Accelerating Decomposition Temperature (SADT) in original packaging is 75ºC.
The explosive instability of the lower dialkyl peroxides (e.g., dimethyl peroxide) and 1,1-bis-peroxides decreases rapidly with increasing chain length and degree of branching, the di-tert-alkyl derivatives being amongst the most stable class of peroxides.
DiCup ® R/Luperox ® DCP dicumyl peroxide is used as a high temperature crosslinker in rubber and plastics applications. Compounds containing DiCup ® R/ Luperox ® DCP are processed at temperatures up to 250°F (121°C) and can be cured at temperatures above 300°F (149°C).
Temperature is the main factor in the rate of decomposition. The lowest temperature at which a packaged organic peroxide will undergo a self-accelerating decomposition within a week is defined as the self-accelerating decomposition temperature (SADT). Safety. Peroxides are also strong oxidizers and easily react with skin, cotton and wood pulp.
Dicumyl peroxide is a strong free radical source ; used as a polymerization initiator, catalyst and vulcanizing agent. The half-life temperatures are 61 C (for 10 hours), 80 C (1 for 1 hour) and 120 C (for 1 minute).

Conjunctiva has become necrotic and the cornea opaque. Dicumyl peroxide was a weak tumor promoter despite its high activity in inducing hyperplasia. Tumor promotion activity of organic peroxides is associated with free radical generation. Dicumyl peroxide causes more than 50% of malformed embryos at any dose in white Leghorn chicken embryos.
Organic peroxide. Heat or contamination may cause hazardous decomposition. Peroxides and decomposition products are flammable and can ignite with explosive force if confined. Causes eye, skin, and respiratory tract irritation. Keep refrigerated. (Store below 4°C/39°F.) Target Organs: Respiratory system, eyes, skin. Potential Health Effects
The major factor affecting the rate of peroxide decomposition and, therefore, cure rate, is temperature. However, the polymer or medium in which the peroxide decomposes does have some effect on rate of peroxide decomposition. Di-Cup® dicumyl peroxide is much less sensitive to its environment than many other peroxides but

Dicumyl peroxide is among the less reactive of the organic peroxides. Large amounts of dicumyl peroxide are used as cross-linking agents in the polymer industry. Exposure of the workers to this compound may occasionally be high, for example when sacks of dicumyl peroxide are cut open and the peroxide is poured into hot melting tanks.
peroxide should be reviewed for specific toxicity and health hazard information. FIRST AID Care should be exercised by all personnel handling dialkyl Inhalation of vapors or decomposition products emitted during processing should be avoided. In case of skin or eye contact with a dialkyl peroxide or its decomposition

Benzoyl peroxide was the first organic peroxide prepared by intentional synthesis. It was prepared by treating benzoyl chloride with barium peroxide, a reaction that probably follows this equation: 2 C 6 H 5 C(O)Cl + BaO 2 → (C 6 H 5 CO) 2 O 2 + BaCl 2. Benzoyl peroxide is usually prepared by treating hydrogen peroxide with benzoyl chloride.
The effect of dicumyl peroxide (DCPO) concentration on the polymerization kinetics of a polysilazane system has been investigated through DSC analyses. DCPO acts as polymerization initiator by activating the polyaddition of vinyl groups.
The behavior of Dicumyl peroxide (DCP) under runaway conditions was studied using low and high phi factor (φ) calorimeters.Solutions of 20, 30 and 40%, by weight, of DCP in 2,2,4-trimethyl-1,3-pentanediol diisobutyrate and cumene were run at different phi factors experiments(1.8 > φ > 1.1).
