DCP-CFF may be used for the (co)polymerization of styrene in the temperature range of 110-165°C. In a mass process DCP-CFF can be advantageously used to increase polymerization rates. DCP-CFF may also be used as synergistic co-agent in combination with halogen containing flame retardants to produce flame-retardant expandable polystyrene.

Half-life data

The reactivity of an organic peroxide is usually given by its half-life (t1/2) at various temperatures. For DCP-CFF in chlorobenzene half-life at other temperatures can be calculated by using the equations and constants mentioned below:

0.1 hr	at 154°C (309°F)
1 hr	at 132°C (270°F)
10 hr	at 112°C (234°F)
Formula 1	kd = A·e-Ea/RT
Formula 2	t½ = (ln2)/kd
Ea	152.67 kJ/mole
A	9.24E+15 s-1
R	8.3142 J/mole·K
T	(273.15+°C) K

Thermal stability

Organic peroxides are thermally unstable substances, which may undergo self-accelerating decomposition. The lowest temperature at which self-accelerating decomposition of a substance in the original packaging may occur is the Self- Accelerating Decomposition Temperature (SADT). The SADT is determined on the basis of the Heat Accumulation Storage Test.

SADT	75°C (167°F)
Method	The Heat Accumulation Storage Test is a recognized test method for the determination of the SADT of organic peroxides (see Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria – United Nations, New York and Geneva).

Storage

Due to the relatively unstable nature of organic peroxides a loss of quality can be detected over a period of time. To minimize the loss of quality, Thousands Chemicals recommends a maximum storage temperature (Ts max. ) for each organic peroxide product.

Ts max.	30°C (86°F)
Note	When stored under the recommended storage conditions, DCP-CFF will remain within the Thousands Chemicals specifications for a period of at least 12 months after delivery.

Packaging and transport

In North America DCP-CFF is packed in non-returnable cartons containing 55. 1 lb net weight. In other regions the standard packaging is a non-returnable carton containing 5 x 5 kg peroxide. Both packaging and transport meet the international regulations. For the availability of other packed quantities contact your Thousands Chemicals representative. DCP-CFF is classified as Organic peroxide type F; solid, Division 5. 2; UN 3110.

Safety and handling

Keep containers tightly closed. Store and handle DCP-CFF in a dry well-ventilated place away from sources of heat or ignition and direct sunlight. Never weigh out in the storage room. Avoid contact with reducing agents (e. g. amines), acids, alkalis and heavy metal compounds (e. g. accelerators, driers and metal soaps). Please refer to the Safety Data Sheet (SDS) for further information on the safe storage, use and handling of DCP-CFF. This information should be thoroughly reviewed prior to acceptance of this product..
