Application

• LIQUID PMS 5-10 is used as damping liquid and thermal liquid (both low- and high- temperature) for instrumentation.

• LIQUID PMS 20-40 is commonly used as damping , hydraulic, parting liquid for instrumentation and as a grease base.

• LIQUID PMS 50-200 is used as damping , hydraulic, parting liquid as well as additives in polishing liquid and various household chemicals..

LIQUID PMS 300-400 is used as a base of petrolatum paste. Water-based emulsions of these liquids are used as release agents in production of general mechanical rubber goods, plastic goods, and rubbers, also in production of dielectric pastes and petroleum jellies , and as damping liquid.

LIQUID PMS 500-1000 is used as damping liquid.

• LIQUID PMS 100R is used as a base constituent of low-temperature greases, refrigerant, and low temperature liquids for a variety of instrumentation.

• LIQUID PMS 200-A is used as foam inhibiting agent for petroleum oils and printing inks in printing industry as well as parting agent in tire industry.

• LIQUID PMS-200,300 and the emulsion on the base of PMS-400 are allowed to use in food industry.
