Saving Costs With Crastin® SF

Crastin® Super Fast (SF) dramatically reduces manufacturing costs by reducing cycle times by enhancing resin flow to extremely high levels.

Crastin® SF has been developed for high volume mouldings where every second of the cycle time counts. Using patented technology, DuPont™ has designed a series of grades that can be cycled much quicker from shot to shot, with minimal impact on the final product properties.

Available in unreinforced, 15% glass filled and 30% glass filled grades, Crastin® SF can reduce melt temperatures by 5-10°C, reduce hold pressure times due to its advanced nucleation properties, reduce cooling times as it reaches its ejection temperature quicker and fill tools quicker due to its reduced viscosity.

Spotlight on Crastin® SF:

  • Improves productivity by up to 30%
  • Reduces machine size due to lower filling pressure
  • Wider processing window
  • Improves flow to fill moulds for thinner or more complex parts
  • Excellent property retention: stress, strain and impact, thermal stability etc.
  • Lower energy consumption
  • Lower rejection rate
  • Direct drop-in replacement for standard PBT grades

Application areas:

  • Connectors such as thin, complex, small parts running in high productivity tools
  • Automotive electronic components such as sensors, relays, control units
  • Coil formers and solenoids
  • Laser marking parts
  • Motor housings, switches, door housings, automotive lighting components
  • Structurally complex parts for furniture and automotive chassis
  • Thickness and weight reduction in parts with thick walls
Crastin SF 1

Comparing standard PBT 15% GF versus Crastin® SF with the same glass content, cycle time reductions of up to 30% can be achieved.

Crastin SF 2

Looking at the spiral flow length of Crastin® SF versus a standard PBT, we can see that Crastin® SF travels further at lower temperatures.
