What are said to be premium-quality TPEs for sensory-neutral applications developed by Polymax Thermoplastic Elastomers, Inc., Waukegan, Ill., are being launched at NPE2015. Based on SBC-type chemistry, these proprietary formulations boast low odor, low extractables, low-gel formation as well as customizable coefficient of friction, clarity, and sealing performance.
Initially, they have been positioned to replace more costly and/or difficult-to- process materials such as silicone rubber elastomers in injection-molded and extruded food and beverage packaging. Specialty formulations of Polymax TPE sensory-sensitive materials can be used to manage permeation of carbon dioxide, water vapor, and oxygen in addition to improving sealing properties in applications such as screw cap liners and engineered wine closures. They can also be used in tubing for the delivery of dairy products, commercial food packaging, and bag-in-box wine.
However, they have significant promise for use in personal-care and other consumer, medical, automotive, and industrial products.
This expanding and technology-driven compounder admits that this development represents a leap in this arena. Says company CEO Martin Lu, “The development of TPE for sensory-sensitive applications was extremely challenging. It required extensive polymer science and compounding expertise, customized manufacturing equipment, and close teamwork with our customers.”
