Compared to other materials, ETPU is particularly abrasion-resistant, which makes it ideal for demanding applications. Its outstanding flexibility makes the particle foam an ideal solution for products that offer optimum energy return or provide efficient cushioning.[\/vc_column_text][\/vc_column_inner][vc_column_inner width=&#8221;1\/2&#8243;][vc_column_text css=&#8221;&#8221;]Thanks to its robustness against abrasion and its soft-touch properties, ETPU remains efficient even in harsh environments.

It is also very durable, which means that products can be used for longer and less waste is produced.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;Is ETPU toxic or harmful to health?&#8221; tab_id=&#8221;gesundheit&#8221;][vc_column_text css=&#8221;&#8221;]No. ETPU is free from harmful substances in accordance with current standards (e.g. RoHS-compliant) and is safe to use.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;Can I dye ETPU products or buy them in different colors?&#8221; tab_id=&#8221;farben-etpu&#8221;][vc_column_text css=&#8221;&#8221;]The material is currently available in white and black. Individual colors are technically feasible, but at the same time tied to large minimum order quantities.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;In what temperature range can ETPU be used?&#8221; tab_id=&#8221;temperaturbereich-etpu&#8221;][vc_column_text css=&#8221;&#8221;]Expanded thermoplastic polyurethane remains functional from approx. -20 \u00b0C to +80 \u00b0C.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;Are there different types of ETPU?&#8221;
