High-performance polyesters

HiPERTUF(TM) polyester resins from Shell Chemical (Akron, OH) are homopolymer 2ƾ dimethyl naphthalate-based polyethylene naphthalate (PEN), which provide a number of benefits over PET, including hotter fill temperatures, better chemical resistance, and improved gas and UV barriers.

HiPERTUFF 35000 is a low molecular weight resin expected to find major uses in injection molded containers and films where high clarity and barrier/temperature or sterilization are requirements. Applications can include medical, cosmetics and chemical-resistant packaging. HiPERTUFF 90000 is a higher molecular weight resin expected to find applications in medical and cosmetics packaging as well as in returnable/refillable containers for wine, beer, water and juices.
