Common Features of Organic Peroxides

Organic peroxides can be used as initiators and catalysts for synthetic resins. In the field of polymer materials, organic peroxides can be used as initiators, crosslinking agents, curing agents, and regulators. Therefore, peroxides can now be applied in many fields and are widely welcomed. So, what are the common organic peroxides and what are their characteristics?

Understand the common organic peroxides and their characteristics

Tert-Butyl peroxybenzoate

Tert-butyl peroxybenzoate is insoluble in water and soluble in organic solvents. It is widely used as initiator in polymerization processes such as ethylene, styrene, propylene, vinyl acetate, diallyl phthalate and isobutylene. In the curing process of unsaturated polyester, it is widely used in the molding process such as SMC, BMC, DMC pulling agent, etc. At the same time, it can also be used in two-component curing system with some more active ones such as MEPK, BPO or TBPO. Store in a cool, ventilated warehouse. Keep away from fire and heat source and prevent direct sunlight. Storage temperature should not exceed 30℃. Package sealed. Should be stored separately from reducing agents and alkalis, do not mix storage. Equipped with the appropriate variety and quantity of fire-fighting equipment. The storage area should be equipped with suitable materials to shelter leaks. Prohibit vibration, impact and friction.

Cyclohexanone peroxide

Cyclohexanone peroxide is a kind of organic peroxide, it is a white crystal, when wet, can be dissolved in water, ethanol and ethylene glycol, but this kind of peroxide can not encounter direct sunlight, impact, reducing agents, flammable materials, etc., because these will make it fire, explosion and other dangers, if accidental fire or explosion of danger, we must use the fire extinguishing agent can play a role To carry out timely remediation.

Dibenzoyl peroxide

Dibenzoyl peroxide powder is made by slowly dropping dilute hydrogen peroxide into chlorinated benzoyl at 0~5℃, it is one of the organic peroxides with strong oxidizing and flammable characteristics, it is very easy to explode when heated, so we must be careful to use it.

The safe use of organic peroxides

• Organic peroxide use place should be kept neat and orderly, shall not occupy the evacuation channel, doors and windows shall not be set to affect the escape and fire rescue obstacles.

• Organic peroxides use places shall not be set up and production of non-living facilities; open fire operations in the workplace is strictly prohibited.

• Organic peroxides use places should be configured to store small quantities of small storage cabinets of hazardous chemicals, the storage amount shall not exceed the amount used on the day.

• Organic peroxides should be used according to the material use and storage characteristics, improve fire prevention, explosion-proof, anti-static, anti-corrosion, anti-leakage and other measures.

• Organic peroxides should use non-sparking explosion-proof tools when dispensing
