Arkema Luperox? 231XL40-SP 1,1-Di(tert.butylperoxy)-3,3,5-trimethylcyclohexane TMCH 6731-36-8

Luperox? 231XL40-SP It is a coke protection product, based onLuperox? 231XL40It is 40% with calcium carbonate and silica as the dispersing carrier.It belongs to the peroxide condensate organic peroxide, and its chemical molecular structure is 1,1'-bis(tert-butylperoxy)-3,3,5-trimethylcyclohexane, CAS No. 6731-36-8, and its molecular weight is 302.4 g/mol.

Main properties::

  • Physical form: powder
  • Peroxide content: 40%
  • Active oxygen content: 4.2%

Scorch protection: Luperox? 231XL40-SP provides superior scorch protection and solves the problems associated with traditional scorch protection. The advantages are:

  • Quickly traps free radicals and provides excellent char protection.
  • Maintains a comparable level of cross-linking without reducing cross-linking density.

performances: Comparison of the vulcanization performance of Luperox? 231XL40 and Luperox? 231XL40-SP in EPDM compounds:

  • equivalent vulcanization time (t90) and maximum torque (MH).
  • At 110°C, Luperox? 231XL40-SP has 5 times the scorch protection time (ts05) of Luperox? 231XL40.

vantage: Good scorch protection improves processing efficiency, including:

  • Improved mixing efficiency can be achieved by increasing the mixing rate to make the rubber mix more homogeneous.
  • Reduce the amount of antioxidant, SP additives can also be used as antioxidants in rubber formulations.
  • Scorch protection reduces downtime to clean equipment and increases production time during the production process.

Vulcanization accelerators: Luperox? 231XL40-SP can be used as a vulcanization accelerator. When mixed with Luperox? F40-SP, the vulcanization rate is faster than with Luperox? F40 alone and maintains the same crosslink density and good scorch protection.

major application: Luperox? 231XL40-SP is mainly used as a vulcanizing agent for the following products:

  • Hoses and window frames
  • Rubber seals and gaskets
  • Technical Products
  • wire and cable
  • golf center
  • EPDM and EVA soles

additive quantity: Typical additions are listed in the table below:

  • EPM: 6-15 phr
  • EPDM: 6-15 phr
  • EVA: 3-6 phr

decomposition product: In inert media, the major decomposition products of Luperox? 231XL40-SP include acetone, tert-butanol, methane, carbon dioxide, trimethylcyclohexane and 3,3,5-trimethylcyclohexanone. Refer to MSDS for detailed information on safety, handling, storage and transportation.
