Cyclopentane (MARUKASOL FH)

"MARUKASOL FH" is a cyclopentane product uniquely developed by us.
Since it shows a low rate of heat transfer, it is used as urethane-foaming agent. With its degrease-cleaning capability and drying property excellently balanced, it may be also used to clean metal parts and semiconductors.
