Syndiotactic polystyrene (sPS)

  • Relatively new to the market, syndiotactic polystyrene is a semi-crystalline high-performance plastic with outstanding properties
  • Used in the electrical engineering, automotive and filter technology industries where its flowability, electrical properties and excellent resistance to chemicals make it ideally suited for application in coolant circuits
Resists high temperatures
If produced with a metallocene catalyst, this high-performance plastic has the abbreviation PS-S or PS-(M). Otherwise, the standard abbreviation sPS is used. When reinforced with 30 % glass fibers, sPS can resist high temperatures and is dimensionally stable up to just beyond 260 °C (500 °F), making it ideal for applications in electrical engineering in which welding is required.
Fast cooling
Syndiotactic polystyrene melts at 270 °C (518 °F). Its melt offers excellent flowability, fast crystallization or cooling and low moisture absorption. This fast cooling reduces the cycle times by up to 30 %. sPS also demonstrates good non-stick properties and high resistance to chemicals and is suited to contact with drinking water.
High performing profiles
The outstanding electrical properties and dimensional stability of sPS are beneficial in many practical applications. Used above all in the electrical engineering, automotive and filter technology industry, it is suited for application in coolant circuits, for example the construction of pump wheels for water pumps.
