Use of existing tooling = lower capital costs: API was able to use the same mold originally designed for nylon to run the Gravi-Tech materials, saving the substantial costs of retooling.

However, the original TPE that the company selected caused issues during 2K molding.

History Originally called HT-1, Nomex® was first developed in the 1960’s and made commercially available in 1967.

In addition, this material can be used in tools originally constructed for halogenated materials with no rework required.
