In addition to a version for clinicians, the company offers the BiowavePRO® non-invasive neuromodulation system designed for individual use by athletes to reduce pain and enhance rehabilitation. In addition to durability, these bumpers needed resilience for a comfortable feel and the ability to incorporate membrane switches. For guidance on materials for the housing, Biowave consulted PTA Corp., its molder, who in turn contacted its long-time partners on the GLS Thermoplastic Elastomers team at Avient.

Newer molding equipment provides additional options for transferring from injection boost (first-stage Injection) to the pack and hold phase. In addition, the material hardness is a factor. The addition of a slight surface texture to the mold can help to mask possible surface blemishes in the molded article.

These grades combine excellent chemical resistance and dimensional stability with improved wear resistance and low coefficient of friction (COF) properties. LubriOne PKE formulations also offer improved chemical resistance and thermal performance, plus reduced flammability, over POM Avient makes no warranties or guarantees respecting suitability of either Avient’s products or the information for your process or end-use application.
