Core Design: It features a robust 316 stainless steel metal core faced on both sides with laminated materials. Dual-Facing System: The gasket combines a Filled PTFE face for superior chemical resistance and tight sealability alongside a proprietary Termica™ (mica-based) layer. Fire Safety: The combination of the metallic core and high-temperature mica allows it to pass stringent industrial fire tests (like API 6FB), functioning reliably even under extreme heat. Isolation Capabilities: It effectively prevents electrochemical corrosion between dissimilar metal flanges or along buried pipelines.
