stakeカジノ (CPME)

stakeカジノ (CPME) is a totally new hydrophobic ether solvent, which was established out of ZEON's unique synthetic technology and C5 raw materials.
Unlike other common ether solvents, CPME has unique excellent properties and is widely applicable as a replacement for Tetrahydrofuran (THF), Methyl Tert-Butyl Ether (MTBE), Dioxane and other existing ether solvents.

TSCA: Approved

EC Number: 445-090-6

Japan: 3-4548
