Avient Versaflex™ CL40 Thermoplastic Elastomer (TPE)
Categories: Polymer; Thermoplastic; Elastomer, TPE

Material Notes: Versaflex™ CL40 is an easy processing compound designed for use in injection molding applications where water-clarity and excellent colorability are required. - Excellent Clarity - Excellent Colorability - Overmold Adhesion to Polypropylene - Soft Touch

Color concentrates with polypropylene (PP), ethylene vinyl acetate (EVA), or low density polyethylene (LDPE) carriers are most suitable for coloring Versaflex™ CL40. 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 a significant 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) polypropylene (PP) or polyethylene (PE). Regrind levels up to 20% can be used with Versaflex™ CL40 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. Drying is not Required Injection Speed: 1 to 5 in/sec 1st Stage - Boost Pressure: 400 to 1000 psi 2nd Stage - Hold Pressure: 30% of Boost Hold Time (Thick Part): 3 to 10 sec Hold Time (Thin Part): 1 to 3 sec
