Organic Peroxides Can Be Used As Good Initiators

Oct 30, 2017

Organic peroxides are the source of free radicals used in the following applications:

(1) radical polymerization and copolymerization initiators of vinyl and diene monomers;

② curing agent for thermosetting resin;

③ elastomer and polyethylene cross-linking agent. In the case of

The decomposition temperature of an organic peroxide at an effective rate largely determines its use. Other important factors are cost, solubility, and safety. Organic Peroxides Efficiency and the type of free radicals generated, the need for frozen storage and freight, compatibility with the production system, the possible impact on the product, and the ability to be activated. Organic peroxides can be controlled at high temperature or room temperature to produce a certain rate of decomposition of reactive radicals. In the case of

All organic peroxides are thermally unstable and decomposed with increasing temperature. The usual quantitative method for the determination of organic peroxides is to determine the half-life, that is, Organic Peroxides the time required for a certain amount of peroxide to decompose at a specific temperature to half its initial amount. The half-life data for commercial organic peroxides are now available on computer floppy disks. Organic Peroxides Use the computer menu program to select the appropriate peroxide for a polymerization or process conditions. In the case of

These free radicals can be added to unsaturated vinyl monomers such as styrene, vinyl chloride or methyl methacrylate to initiate polymerization. Some free radicals also attack polymers such as PE to generate free radicals in the chain. When two such polymer radicals are bound together, Organic Peroxides a crosslinked structure is formed. Organic peroxides

More than 50 different organic peroxides are available, including pure substances and more than 100 different formulations, such as solvent diluents, pastes and fillers. In the case of

Oxidation of benzoic acid is the first and commonly used organic peroxide, as a granular solid, stable at ambient temperature. To improve safety, benzoic acid can add 22% or 30% by weight of water to a wet product to reduce flammability and vibration sensitivity. In addition there is a concentration of 25% to 50% of the oxidized benzoic acid paste formula. In the case of

Benzo benzoic acid can be used in vulcanized polyesters over a wide temperature range. It can be activated by tertiary amines at room temperature and used in vulcanized filled polyester composites over a temperature range of 250 to 300 ° F. In the suspension polymerization of styrene, Organic Peroxides benzoic acid can be used as a good initiator. In the case of

For safety and anti-decomposition considerations, organic peroxides should always be stored at the appropriate temperature to store them in the original container to reduce the chance of contamination, Organic Peroxides especially the possibility of being strongly acidified, which is very important The Care should be taken when using ketone peroxides because ketone peroxides react quickly when the transition metal salt concentration is very small. Organic peroxide in the transport should be as far as possible shock, anti-friction, anti-upside down, Organic Peroxides should wear protective equipment in use, to avoid sticking to the skin or into the eyes. The disposal of organic peroxides can be used for incineration, hydrolysis, deep burial and other methods.
