Coloring
Color concentrates with Versaflex® CL2000X as the carrier are most suitable for coloring this product. If a CL2000X color concentrate carrier is desired, it is important that the chosen color house have underwater pelletization capabilities. Typical loadings for color concentrates are 1% to 5% by weight. Liquid color (pigment, not dye) can be used; white oil carriers are recommended. A high color match consistency can be obtained by using precolored compounds available from GLS. Polypropylene (PP) based color concentrates are not recommended because they lead to poor dispersion and can significantly change the hardness of the material. Concentrates based on PVC should not be used. The final determination of color concentrate suitability should be determined by customer trials.
Purging
Purge thoroughly before and after use of this product with a low flow (0.5 - 2.5 MFR) polyethylene (PE) or polypropylene (PP).
Regrind
Regrind levels up to 20% can be used with Versaflex® CL2000X with minimal property loss, provided that the regrind is free of contamination. To minimize losses during molding, the melt temperature should remian as low as possible. The final determination of regrind effectiveness should be determined by the customer.
