GYLON® Style 3504 Blue PTFE Gasket Sheet – Chemically Resistant, Low Creep PTFE Sealing | 1.5mm and 3mm

GYLON® Style 3504 is a premium blue PTFE gasket material filled with aluminosilicate microspheres, engineered for demanding chemical and industrial sealing applications. This high-performance material offers significantly improved chemical resistance, bolt load retention, and creep resistance compared to standard PTFE sheets.

Unlike traditional skived or expanded PTFE, GYLON® 3504 resists cold flow and deformation under pressure, making it ideal for long-term, reliable sealing under harsh conditions. With exceptional performance in moderate concentrations of acids, caustics, hydrocarbons, solvents, and more, it is widely used in chemical processing, pharmaceuticals, food, and power generation industries.

This gasketing material minimizes leakage and emissions, reduces product loss, and helps lower maintenance costs—making it not only efficient but also environmentally friendly.
