Hongwo Sealing Sheet
Product Introduction
Hongwo’s Soft Flexible Etched PTFE Sheet is an advanced, microporous material engineered for superior flexibility, chemical resistance, and durability. Through a proprietary etching process, the surface is modified to enhance adhesion, sealing, and filtration performance while maintaining PTFE’s inherent properties. Ideal for demanding industrial, medical, and electronic applications.
Key Applications
✅ Gaskets & Seals – Conforms to irregular surfaces, ensuring leak-proof performance in chemical processing and oil/gas industries.
✅ Medical & Pharma – Biocompatible, used in sterile packaging, implantable devices, and lab equipment.
✅ Electronics – Dielectric insulator for flexible circuits, wire insulation, and EMI shielding.
✅ Filtration – Custom pore sizes for air/fluid filtration in harsh environments.
✅ Automotive – Lightweight, heat-resistant components for fuel systems and sensors.
