Avient Versaflex™ HC MT555 Thermoplastic Elastomer (TPE)
Categories: Polymer; Thermoplastic; Elastomer, TPE

Material Notes: Versaflex™ HC MT555 is an easy processing material designed for applications where FDA compliance and medical testing is required. - Excellent Colorability - Soft Touch

Rear: 340 - 360F Center: 380 - 400F Front: 390 - 410F Screw: 80 - 200 RPMs

Color concentrates with polypropylene, ethylene vinyl acetate, or low density polyethylene carriers are most suitable for coloring Versaflex™ HC MT555. 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. Liquid color can be used, but mineral oil based carriers may have an effect on the final hardness value. Concentrates based on PVC should not be used. A high color match consistency can be obtained by using precolored compounds available from GLS. 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 or polypropylene. Regrind levels up to 20% can be used with Versaflex™ HC MT555 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. Versaflex™ HC MT555 has excellent melt stability. Maximum residence times may vary, depending on the size of the barrel. Generally, the barrel should be emptied if it is idle for periods of 8 - 10 minutes or longer. Drying is not Required Injection Speed: 1 to 5 in/sec 1st Stage - Boost Pressure: 100 to 800 psi 2nd Stage - Hold Pressure: 20% of Boost Hold Time (Thick Part): 4 to 10 sec Hold Time (Thin Part): 1 to 4 sec
