The Elastomers team at Huntsman International is celebrating 45 years since the launch of its KrystalGran surface protection products. The anniversary coincides with the company’s expansion of manufacturing capacity at its Ringwood, Illinois, site, where it produces its KrystalGran non-optical aliphatic thermoplastic polyurethane (TPU) pellets and its range of KrystalFlex optical aliphatic TPU films.

Earlier this year Huntsman opened a new building at its Ringwood plant. The purpose-built facility has been fitted out with the latest automated manufacturing equipment, increasing Huntsman’s production capacity and its ability to run customer trials. The investment is the latest milestone, the company says, in its work in the safety glazing and surface protection markets. The company introduced KrystalGran PE192, an optical aliphatic technology, in 1975.

Huntsman’s TPU products are used in surface protection and safety glazing applications internationally.KrystalFlex films are used for interlayer laminating applications within the glass industry. The materials are used to strengthen anti-ballistic glass used in military vehicles, banks and government buildings. KrystalGran products, which are sold as pellets, are used to enhance paint protection in the automotive industry, for electronic film applications, in signage projects, and to protect the leading edge of helicopter and wind turbine blades.
