PolyOne Versalloy™ HC 9220-70 Thermoplastic Elastomer (TPE)

Versalloy™ HC 9220-70 is a TPV alloy targeted for extrusion and injection molding healthcare applications such as medical tubing, disposable medical items and soft-touch overmolding for surgical grips. Product exhibits exceptional flow properties and surface aesthetics. * Excellent Extrudability * Good Flow for Injection Molding * Exceptional Colorability * Overmold Adhesion to Polypropylene * Superior Surface AestheticsVersalloy™ HC 9220-70 can be recycled as a filler or impact modifier for polyolefins, or can be recycled by grinding and reintroduction to the molding process. Similar to PP or PE recycling process, if separated appropriately, it can be recycled many times. Municipality waste stream recycle code is 7 which is designated for Other. Please contact GLS Thermoplastic Elastomers for a copy of our Recyclability Compliance letter.Color concentrates with polypropylene (PP) carrier are most suitable for coloring Versalloy™ HC 9220-70. Improved color dispersion can be achieved by using higher melt flow concentrates (with a melt flow from 25 - 40 g/10 min). Typical loadings for color concentrates are 1% to 5% by weight. Concentrates based on PVC should not be used. The final determination of color concentrate suitability should be determined by customer trials. Purge thoroughly before and after use of this product with a low flow (0.5 - 2.5 MFR) polyethylene (PE) or polypropylene (PP). Regrind levels up to 20% can be used with Versalloy™ HC 9220-70 with minimal property loss, provided that the regrind is free of contamination. To minimize losses during molding, the melt temperature should remain as low as possible. The final determination of regrind effectiveness should be determined by the customer. Versalloy™ HC 9220-70 has good melt stability. Empty the barrel for idle periods of fifteen (15) minutes or longer. Injection Speed: 1 to 5 in/sec 1st Stage - Boost Pressure: 300 to 700 psi 2nd Stage - Hold Pressure: 30% of Boost Hold Time (Thick Part): 4 to 10 sec Hold Time (Thin Part): 1 to 3 secInformation provided by PolyOne
