Compounding Solutions’ Fuse RX Tie-Layer resin

Lewiston, Maine – Compounding Solutions engineers have developed a new tie-layer resin known as Fuse Rx. There are three grades of Fuse Rx: Fuse Rx 101, 201, and 301, representing LLDPE-, EVA-, and EMA-based resins to meet all adhesion needs. All grades of Fuse Rx show excellent adhesion to Pebax, TPU, and HDPE resins.

Fuse Rx Tie-Layer resin is a polyolefin modified with Maleic anhydride or other adhesion promoters; it can be used as the tie layer in the production of multilayer co-extruded catheter tubing and bonds materials that would typically not adhere together during processing.

Fuse Rx resins were tested and passed ISO-10993-05 Cytotoxicity testing. Fuse Rx can be used in disposable Class I & Class II devices.

“The current tie-layer resins in the market have been subject to numerous changes over the last five years, along with complete discontinuation of certain grades. Coupled with the resistance of the manufacturers to offer medically approved grades, this has placed much uncertainty within the coextrusion device market,” says Nathan Doyle, sales & marketing manager, Compounding Solutions.  

“Fuse Rx is the only for medical use tie-layer resin in the market, and will be subject to no-change agreements.”
