The brand or blow molder must stipulate the importance of using a blow molding process aid. Typically, energy savings alone is sufficient to advance to the production blow molding stage. When brands and preform manufacturers incorporate blow molding process aids, however, they can see several significant benefits:

However, the original TPE that the company selected caused issues during 2K molding. The company had the opportunity to conduct molding trials to ensure ideal temperature and pressure parameters.  With its enhanced processability, the OnFlex-S thermoplastic elastomer enabled the company to solve its 2K molding issues and reduce system costs.
