				| Korfron-142b |  |  |  | 1, 1-Difluoro-1-chloroethane |  |  |  | 75-68-3 |  |  |  | * Applications: -Blowing Agents: Polystylene, polyethylene.
 -Aerosol propellent for man use.
 * Characteristics:
 -Mixed with K-22 to in a ratio of 6 to 4, almost same pressure was formed and thus, used as a blowing agents for polystylene.
 -It is inflammable so that special care is on priority for treatment.
