Popular Applications of PPS

The excellent properties of PPS with its ease of production and moderate cost makes it one of the most suitable choices for various applications where cost and high performance are essential.

Overview

Key Applications

Automotive Applications/ Automobile Parts


Polyphenylene Sulfide applications in automotive market have seen strong growth mainly due to its ability to replace metal, thermosets and other types of plastic, in more demanding applications. It is an ideal choice for automotive parts exposed to:

  • High temperatures, 
  • Automotive fluids, or 
  • Mechanical stress

PPS is a lighter weight alternative to metals, resistant to corrosion by salts and all automotive fluids. The ability to mold complex parts to tight tolerances and insert molding capability accommodate multiple component integration.

Under-the-hood is the largest application area for PPS followed by electrical parts. PPS applications in automotive include fuel injection systems, coolant systams, water pump impellers, thermostat holder, electric brakes, switches, bulb housing and so on.

It is rarely used for the manufacture of interior or exterior auto parts.

Electronic and Electrical Applications


Owing to its high temperature resistance, high toughness, good dimensional stability and good rigidity, PPS becomes an ideal material of choice in E&E market.

  • Offers excellent flow and low shrinkage for precision molding of connectors and sockets
  • Provides superior stiffness and mechanical integrity for reliable assembly, and
  • Is the most stable material choice for all soldering methods

PPS compounds also have UL94 V-0 flammability ratings without the use of flame retardant additives. Special low flash grades have been developed to meet the needs of high precision molding applications. In the electrical / electronic sector, Polyphenylene Sulfide is also used to manufacture a range of articles including bobbins and connectors, hard disk drives, electronic housings, sockets, switches and relays. The key trend influencing PPS growth in electrical / electronic applications is substitution of other lower temperature polymers.


Appliances


Thanks to its exceptional dimensional stability, low density, corrosion- and hydrolysis resistance, PPS can be used to manufacture heating and air conditioning components, fry pan handles, hair dryer grills, Steam iron valves, toaster and dryer switches, microwave oven turntables etc. in electric appliances.


Industrial Applications


PPS has been replacing metal alloys, thermosets, and many other thermoplastics in mechanical engineering applications. The thermal stability and broad chemical resistance of Polyphenylene Sulfide make it exceptionally well suited to service in very hostile chemical environments.

  • It finds uses in many heavy industrial applications, including some outside the arena of reinforced injection molding compounds
  • It is used in fiber extrusion as well as in non-stick and chemical resistant coatings
  • It is well suited to manufacture mechanically and thermally highly stressed molded parts
  • In machine construction and precision engineering, PPS is used for various components such as pumps, valves and piping
  • It can also be found in oil field equipment such as lift and centrifugal pump components, oil patch drop balls, rod guides and scrapers
  • In the heating, ventilation and air conditioning (HVAC) equipment sector, Polyphenylene Sulfide is used for compressors, mufflers/reservoirs, hot water circulation components, induced draft blower housing, motor relays and switches, power vent components and thermostat components
