Did you know…
… that in many cases you can switch from PA 66 to PA 6 and PBT without having to make adjustments to your tools? “Drop-in” and “running change” solutions are possible. For larger components, such as cylinder head covers, PA 66, for example, can be very easily substituted by PA 6 – with few or no adjustments at all to the tool. And due to its PA 66-like shrinkage, PBT can also be used as an alternative in ongoing production – again often even without any tool adaptation.
PA 6 has significantly lower shrinkage and distortion values than PA 66 – we have proven this in our own application tests. What brings immense advantages right from the start in new projects with new tools due to better tolerance compliance, must be compensated on the existing tool during ongoing production.
The larger the component to be produced, the better the result. Because with the then larger tolerances, the constant and ultimately better shrinkage and distortion values of PA 6 are no longer a factor.
When switching from PA 66 to PBT, you have even less to worry about when it comes to different shrinkage and warpage values – PBT shrinks in a similar way to PA 66. Therefore, it is basically possible to switch from PA 66 to PBT during ongoing production. Partly without prior tool adjustments. With polybutylene terephthalates (PBT), you also benefit from significantly better electrical shielding. This makes the material a true all-rounder, especially in the fields of electronics and electrical engineering or e-mobility.
