In contrast to classic particle foams such as EPP and EPS, EPPE has a significantly higher temperature resistance, better dimensional stability and &#8211; depending on the material type &#8211; meets strict flame retardancy standards such as UL94 V-0, making the material particularly suitable for safety-critical applications.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;What is SunForce\u2122 and how is it related to EPPE?&#8221; tab_id=&#8221;material-geraetegehaeuse&#8221;][vc_column_text css=&#8221;&#8221;]SunForce\u2122 is a high-performance foam developed by Asahi Kasei based on modified polyphenylene ether (m-PPE). Technically, SunForce\u2122 therefore belongs to the same family of materials as EPPE.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;In which applications is EPPE superior to other foams?&#8221; tab_id=&#8221;unterschied-epp&#8221;][vc_column_text css=&#8221;&#8221;]EPPE shows its strengths wherever there are high technical requirements in terms of temperature and fire behavior &#8211; in battery systems, electronic housings and flame-retardant components.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;How does EPPE recycling work?&#8221; tab_id=&#8221;epp-im-alltag&#8221;][vc_column_text css=&#8221;&#8221;]The recycling process includes sorting and shredding, regranulating, re-foaming and recycling into new molded parts. As EPPE is thermoplastic, the material can be recycled several times without losing much of its properties.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;How does EPPE differ from EPP?&#8221; tab_id=&#8221;epp-kleine-serien&#8221;][vc_column_text css=&#8221;&#8221;]EPP (expanded polypropylene) is a very robust all-round foam with excellent energy absorption, high resilience and very good thermal insulation properties.<\/p>\n<p>In comparison, EPPE is more temperature-resistant and flame-retardant. Furthermore, more delicate geometries are possible.<\/p>\n<p>However, EPP remains the better choice for highly dynamic crash requirements and cost-optimized technical applications.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;Can EPPE be combined or foamed with other materials?&#8221; tab_id=&#8221;langlebigkeit-epp&#8221;][vc_column_text css=&#8221;&#8221;]Yes, EPPE is very easy to foam. In this way, hybrid components with metals, electronics or inserts of various kinds are created in a single production step, for example in combination with battery and electronic components.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;How does EPPE behave at high temperatures?&#8221; tab_id=&#8221;epp-vergleich-styropor&#8221;][vc_column_text css=&#8221;&#8221;]EPPE is dimensionally stable up to well over 120 \u00b0C, heat-resistant for short periods up to approx. 150 \u00b0C and low shrinkage and distortion under continuous load. Depending on the density and material type, the material is therefore particularly useful for high-temperature zones in vehicles or electronics.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;How does EPPE burn?&#8221; tab_id=&#8221;epp-co2-bilanz&#8221;][vc_column_text css=&#8221;&#8221;]Depending on the material type, EPPE achieves UL94 V-0 and is therefore self-extinguishing. It therefore burns with hardly any dripping and low smoke gas development and then extinguishes completely.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;Is EPPE more expensive than other foams?&#8221; tab_id=&#8221;epp-schaeumen&#8221;][vc_column_text css=&#8221;&#8221;]Yes, the material price of EPPE is higher than that of EPP or EPS.<br \/>\nDepending on the requirements for the subsequent component, the material is nevertheless attractive and sensible, because the higher material costs are often offset by advantages such as weight reduction and safety requirements that can be met.[\/vc_column_text][\/vc_tta_section][\/vc_tta_accordion][\/vc_column][\/vc_row][vc_row][vc_column]\n<div class=\"spacer spacer--large\" style=\"height:100px\"><\/div>\n<div class=\"spacer spacer--medium\" style=\"height:75px\"><\/div>\n<div class=\"spacer spacer--small\" style=\"height:50px\"><\/div>\n[\/vc_column][\/vc_row][vc_row][vc_column]          <div class=\"teaser-container teaser-container--two-colum\">\n\n        \n    <div class=\"ruch-teaser-card bg--gray  wpb_animate_when_almost_visible wpb_fadeInLeft fadeInLeft\">\n        <div class=\"teaser-card-content\">\n          <h3>EPP<\/h3>\n<p>EPP is the material of choice in a wide range of lightweight construction applications.
