CONTINUUM™ DMDA-1260 NT 7
HDPE
陶氏化学(Dow Chemical)
产品描述
CONTINUUM™ DMDA-1260 NT 7 High Density Polyethylene Resin (HDPE) is intended for use in compression and injection molded beverage closures designed primarily for applications that undergo hot fill or aseptic sterilization processes. CONTINUUM™ DMDA-1260 offers improved performance for injection molded fitments designed for fitted pouches where its balance of properties are desired. CONTINUUM™ DMDA-1260 delivers a combination of improved properties such as improved stiffness, higher heat deflection temperature, improved ESCR, and easy processing versus alternative HDPE systems typically used for hot fill and aseptic sterilization processes. The end results are longer term closure performance, easy opening closures without the use of slip agent and consistent processing.
Main Characteristics:
Excellent Stiffness, ESCR, and Impact Strength
Excellent Sensory Properties
Excellent Processing Characteristics
High Heat Deflection Temperature
Controlled Sensory Properties
Complies with:
U.S. FDA 21 CFR 177.1520(c)3.2a
Europe Commission Regulation (EU) No 10/2011
