Avient Dynalloy™ OBC8000-T05 Thermoplastic Elastomer (TPE)
Categories: Polymer; Thermoplastic; Elastomer, TPE

Material Notes: Dynalloy™ OBC8000-T05 is an ultra-soft TPE utilizing the unique rubber properties of Dows INFUSE™ Olefin Block Copolymers. This product is designed for injection molding applications where exceptional softness and overmolding to polypropylene is desired New Product. Commercial specifications have not been established. - Adhesion to Polypropylene - Enhanced Flow - Excellent Colorability - Tactile Feel - Ultra Soft

Color concentrates with Dynalloy™ OBC8000-T05 as the carrier are most suitable for coloring this product. If a OBC8000-T05 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. Purge 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™ OBC8000-T05 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™ OBC8000-T05 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 Required Injection Speed: 0.5 to 3 in/sec 1st Stage - Boost Pressure: 200 to 700 psi 2nd Stage - Hold Pressure: 20% of Boost Hold Time (Thick Part): 1 to 5 sec Hold Time (Thin Part): 1 to 3 sec
