Applications
- Fluids PMS 5-10 are used as damping liquids and thermal liquids (both low- and high- temperature) for instrumentation.
- Fluids PMS 20-40 are commonly used as damping , hydraulic, parting liquids for instrumentation as well as grease base.
- Fluids PMS 50-200 are used as damping , hydraulic, parting liquids as well as additives in polishing liquids and a variety of household chemical goods.
- Fluids PMS 300-400 are used as a base of petrolatum paste. Water-based emulsions of these fluids 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.
- Fluids PMS 500-1000 are used as damping liquid.
- Fluid PMS 100R is used as a base constituent of low-temperature greases, refrigerant, and low-temperature liquids for a variety of instrumentation.
- Fluid 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.
- Fluids PMS-200,300 and the emulsion on the base of PMS-400 are allowed to use in food industry.
