MEKP (PX) PHTHALATE FREE

CAS No. : 1338-23-4
EINECS/ELINCS No. : 215-661-2.

MEKP (PX) PHTHALATE FREE

Description:
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, we recommend a maximum storage temperature. (Ts max.) for each organic peroxide product.
For MEKP (PX):Ts max.= 250C
PHTHALATE FREE
When stored under the recommended storage conditions, will remain within the limit for a period of at least six months after delivery.

APPLICATIONS

  • Methyl ethyl ketone peroxide (MEKP) is used for the curing of unsaturated polyester resins in the presence of cobalt octoate accelerator at room and elevated temperatures.
  • For room temperature application it is necessary to use MEKP together with a cobalt accelerator (e.g.Accelerator).
  • This catalyst gives much faster gel time required for GRP pipe manufacturing.

Solubility

  • Slightly soluble in water and organic solvents

Packaging

  • 30 KG HDPE Carboy

Thermal stability

  • Organic peroxides are thermally unstable substances, whic 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 
  • For Mekp (Px): 600C
  • Phthalate 
  • Freesadt
  • Emergency Temperature(Tem) : 550C

Safety and handling

  • Keep containers tightly closed. Store and handle MEKP and handling in a dry well-ventilated place away from source of
    heat or ignition and direct sunlight.
  • Avoid contact with reducing agents (e.g.amines), acids, alkalis and heavy metal compounds (e.g.accelerators, driers and metal soaps).
