Dryflex TPE Delivers on Compression Set Performance

The HEXPOL TPE group, which brings together the ELASTO and Müller Kunststoffe businesses, has developed a range of TPE compounds with optimised compression set performance.

The range of thermoplastic elastomers (TPE), known as Dryflex CS, are based on SEBS and have been engineered to deliver low compression set values. Compression set is the measure of permanent deformation remaining when an applied force is removed. A TPE sample is compressed to a specific deformation, for a specified time and at a specific temperature. The compression set value is the percentage of the sample that fails to recover to its original height and is an important performance indicator for applications such as seals, flexible connectors and gaskets. For a 40 shore A hardness TPE, typical compression set values are 65 to 70 percent, with the Dryflex CS range this is reduced to 40 percent (22 hours at 100 degree).

The raw materials used to manufacture Dryflex CS TPE compounds are compliant with FDA and 10/2011 EC regulations, the compounds also offer excellent organoleptic performance. The range includes hardnesses from 40 to 90 shore A with a service temperature range from -40 to 100 degree centigrade. The compounds are suitable for injection moulding and extrusion and adhere to PP and PE for 2K applications. The compounds are easy to colour with transparent grades available.

“Our goal is to engineer intelligent TPE solutions which precisely match application requirements, but also to find solutions that meet gaps in the market. We continually develop new material combinations that push the performance and design possibilities of our compounds” commented Klas Dannäs, Global R&D Coordinator at HEXPOL TPE. “Our new Dryflex CS range was developed to address demands for TPE compounds that deliver low compression set values”.
