Material Notes:
Dynalloy™ OBC8200-BT50 is a translucent grade to be used in blow molding applications. New Product. Commercial specifications have not been established. - Excellent Colorability - Rubbery FeelPurge thoroughly before and after use of this product with a low flow (0.5 - 2.5 MFR) polystyrene (PS) or polypropylene (PP). Regrind levels up to 20% can be used with Dynalloy™ OBC8200-BT50 with minimal property loss, provided that the regrind is free of contamination. To minimize losses during molding, the melt tempetature should remain as low as possible. The final determination of regrind effectiveness should be determined by the customer. Dynalloy™ OBC8200-BT50 has good 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 RequiredInformation provided by PolyOne
