FLEXIFESTOON\u00ae PUR enables \u221250 to +90\u00b0C operation\u2014a 140\u00b0C envelope impossible with PVC. Additionally, PVC lacks halogen-free compliance; contains restricted plasticizers (EU RoHS concern).<\/p>\n<p><strong>vs. EPDM Vulcanized:<\/strong> While EPDM achieves comparable mechanical properties, FLEXIFESTOON\u00ae PUR offers 2\u20133\u00d7 superior tear strength (exceptional for high-stress applications) and dramatically better flex-fatigue life (<5% loss vs. 15\u201325% for EPDM after 1 million cycles). PUR's thermoplastic nature eliminates reversion loss (EPDM loses 5\u20138% per year at +90\u00b0C). Most importantly, PUR enables drum-reel automated feeders (thermoplastic can be tightly wound); EPDM vulcanized cannot (permanent set).<\/p>\n<p><strong>vs. Silicone-Sheathed:<\/strong> Silicone achieves exceptional high-temperature performance (+200\u00b0C) but cannot reach \u221250\u00b0C without brittleness. FLEXIFESTOON\u00ae PUR fills the gap for \u221250 to +90\u00b0C requirements. Silicone also costs 150\u2013200% more; PUR offers better cost-performance balance.<\/p>\n<p><strong>vs. Halogenated Flame-Retardant Cables:<\/strong> Traditional halogenated cables (still prevalent in some markets) release HCl\/HBr and dioxins during fire. FLEXIFESTOON\u00ae PUR eliminates this toxicological hazard entirely\u2014critical for worker safety and regulatory compliance (EU RoHS, China\/Japan halogen-free initiatives).
