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:
Comparing standard PBT 15% GF versus Crastin® SF with the same glass content, cycle time reductions of up to 30% can be achieved.
Looking at the spiral flow length of Crastin® SF versus a standard PBT, we can see that Crastin® SF travels further at lower temperatures.
