Designation:complete
synthesis Freon-free copper pipe drawing oil Model:BYH-46,BYH-32 Standard:200L/cask Performance:
The BTH- series have the good anti-burning , high degree of glue
number and good stabilities, mobility.Have the good fire prevention
safety while near to the fire source and the heat high pressure
environments.Still be applicable to the aluminum, zinc to die-casting
machine, extruder,steel machine, the glass to model machine, thermal
power machine and coke's door of control mechanism etc.,Have the
good function, can prevent from availably because a fire that
liquid presses to lubricate the system to reveal to result in.
