The antimicrobial technologies, tested in compliance with JIS Z2801 and ASTM G21-15 standards, actively inhibit the growth of bacteria, fungus, and mold that cause odor and detrimental aesthetic and mechanical property changes to the finished, molded part. Specialty TPE with imbedded antimicrobial additives to help protect the finished part; suitable for injection molding and overmolding onto PP TPE formulated with antimicrobial additives for automotive applications, suitable for injection molding and overmolding to PP

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:

Injection molded TPEs are easily processed in complex molds, and it’s easy to add surface texture by bead blasting or chemically texturing the mold. Cycle times for injection molded TPEs are typically faster than alternative materials, resulting in reduced production costs.
