Compounding Solutions has developed a new tie-layer resin that bonds resins in coextruded catheter tubing.
The Lewiston, Maine, company says its three grades of Fuse Rx are based on linear low density polyethylene, ethylene/vinyl acetate and ethylene/maleic anhydride. It claims they adhere very well to difficult-to-bond resins such as polyether block amide, thermoplastic polyurethane and high density polyethylene.
The firm says they pass cytotoxicity testing and can be used in disposable Class I and 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,” explains Compound Solutions sales and marketing manager Nathan Doyle. Uncertainty in the marketplace is made worse by reluctance of some resin suppliers to offer medically approved grades, Doyle adds.
Fuse Rx materials are based on polyolefins modified with maleic anhydride or other adhesion promoters.
