LEOMINSTER, MA (January 29, 2024) – Peak Performance Compounding (PEAK-PCI) is excited to announce its latest polymer technology – Synnergy™ –a custom line of low-friction compounds for single and dual-layer tube extrusion, injection molding, and blow molding applications.  

Synnergy™ compounds are custom-formulated using a proprietary blend of lubricious additives to significantly reduce the coefficient of friction (COF) of natural resins, including Polyether Block Amide (PEBA) and Thermoplastic Polyurethane (TPU). As a safe and durable alternative to PTFE, Synnergy™ formulations can be customized using colorants and other performance-enhancing additives for industrial and medical (Synnergy™ Rx) products, including interventional and diagnostic catheters, industrial tubing, and component parts. 

In two separate studies for lubricious catheter liners conducted in November and December of 2023, Synnergy™ Rx formulations outperformed competing solutions in Polyether Block Amide compounds. Synnergy™ Rx samples were found to have 14% – 68% lower COF compared to competing samples in Pebax® 63D when pulled at varying pressures (4, 6, and 8 psi). In medical applications, specifically catheter liners, low friction is essential for interior device insertion and maneuverability. Additionally, a reduction in overall polymer friction enables enhanced processability and ease of extrusion; often reducing material scrap and improving production yields. Synnergy™ Rx formulations have passed USP Class VI testing for biocompatibility.
