Lubrizol to highlight aliphatic thermoplastic polyurethanes at Chinaplas 2014

Building on the improved UV and staining resistance shown by Pearlthane 91T85 (88 Shore A) in moulded parts like watch belts and weatherable electronic devices, Lubrizol has expanded its aliphatic TPU offering commercialised under Estane Engineered Polymers. The aliphatic portfolio now includes new as well as improved moulding grades for the industrial, automotive, sports and recreation, and electronics markets.

Driven by the increasing demand for light colours and/or optical clarity in several technical and fashion-end applications, the latest developments from Estane Engineered Polymers have resulted in an improved formula for Pearlthane D91T80. This aliphatic TPU grade (82 Shore A), offers very good colour stability upon UV exposure and also features excellent elasticity properties. Additionally, the product has been recently introduced, with a 90 Shore A hardness, to obtain a faster processing and better cycling time, while retaining good surface finish and appealing aesthetics, making it suitable for automotive interior parts, like gear knobs and shutter pads.

Junkers Wang, regional industrial market segment manager for Estane Engineered polymers, notes "Our aliphatic TPU innovations have received an amazing response from our customers. As an added value, apart from obtaining good haptics and a nice looking part, the new aliphatic TPU grades also show an improvement in mechanical properties.
