Specialty Polymers + Chemicals, Zeon products



Cyclopentyl Methyl Ether (CPME) is a new hydrophobic ether solvent which was established out of ZEON’s unique synthetic technology and C5 raw materials.

CPME has unique excellent properties and is widely applicable as a replacement for Tetrahydrofuran (THF), Methyl Tert-Butyl Ether (MTBE), Dioxane and other existing solvents:

  • High Hydrophobicity: easy separation and recovery from water, reducing emissions and waste water. Wide applicability as a reaction, extraction and crystallization solvent, giving simple one-pot syntheses.
  • Wide Liquidity Range: wide applications from lower to higher temperature, accelerating reaction rate.
  • Low Heat of Vaporization: Saving energy for distillation and recovery.
  • Low Peroxide Formation: Low exothermic decomposition energy of the peroxide.
  • Narrow Explosion Area
  • Stable to Acids and Bases
  • Easy Drying



ZEORORA® is an environmentally friendly, new generation HFC, developed for a variety of applications to meet customers’ requirements offering good solubility on precision cleaning and good solubility for fluorocarbon polymer with functional group: anti-fingerprint; water/oil-repellent; lubrication.
