【Introduction】
Trade name: initiator EHP C60, C75
Molecular formula: C18H34O6
Molecular weight: 346.46
Structural formula:
EHP is colorless or yellowish transparent liquid (pure). Theoretical active oxygen content: 4.62%; automatic decomposition accelerating temperature: +5℃.
Half-life temperature (taking chlorobenzene as dilution solvent):
The reaction activity of peroxide at different temperature is decided by half life period t1/2 (sec). The corresponding temperature is 83℃, 64℃ and 47℃ when the half life period is 0.1hr, 1hr and 10hr.

【Application technique 】
Initiator EHP C60, C75 can be usd as initiator for PE suspension polymerization and bulk polymerization at 50-65℃. It can whether be solely used or used together with other initiator.
It has the advantages of high initiating efficiency, stable reaction, uniform heat releasing, and can shorten polymerization time and heighten the production capability of the pot.
【Packing and storage】
plastic drum, , net wt 20kg.or in accord with client's requirements...
EHP products shuld be stored in lightproof refrigeratoreis with temperature below -15℃. Alarm temperature: -5℃. Please keep it away from heat resources, fire resources, accelerant, stabilizer, heavy metal compound and iron rust. Don't put it in the place with hidden tanger of fire. Effective period: 3 months. It can still be used after effective period is tested to be qualified. .
During transportation, it should be placed in -15℃ refrigerated containers. It can not be transported by train, and it needs special permit if transported by sea or by land. Please load and unload it as fast as rapidly, to shorten the time of it exposed in the air.
【Attention】
Flammability: EHP C60, C75 is inflammable product. The main decomposition products after ignited are carbon dioxide and 2-ethylhexanol.
Protection: This product can be treated as inflammable low-toxicity chemicals. Please take safety measures when use it. It is pungent to eyes, slightly pungent to skin, and has some toxicity (oral toxicity, rat: LD50: 1020mg/kg). Don't contact it to eye or skin. Don't eat it.
Please rinse the eyes and skin with large amount of water if contacting it. When preparing or treating initiator, please wear protection mask, rubber gloves and apron. Be care of high-pressure vapor and hot solution, to avoid scalding.
