3M™ Nextel™ AF-20 Fabric Supplier & Exporter in India
Premium 3M™ Nextel™ AF-20 Fabric
Marshall Packings & Insulations Industries is a trusted supplier and exporter of 3M™ Nextel™ AF-20 Fabric, a premium medium-weight woven ceramic fabric manufactured from 3M™ Nextel™ 312 high-temperature continuous ceramic oxide roving. Designed for demanding thermal environments, AF-20 Fabric delivers outstanding flame resistance, oxidation resistance, mechanical strength, and thermal stability while maintaining excellent flexibility and low air permeability. It is engineered to outperform conventional glass, silica, and refractory fabrics in high-temperature industrial and aerospace applications.
The AF-20 style features a 5 Harness Satin weave using 1800 denier roving, providing superior drapeability, excellent structural integrity, and reliable thermal barrier performance. It is widely used for furnace curtains, thermal barriers, expansion joints, flexible seals, gaskets, sewn refractory components, ceramic matrix composites (CMC), and industrial thermal insulation systems.
Its ceramic oxide fiber construction offers excellent dielectric insulation, chemical resistance, and long-term dimensional stability under repeated thermal cycling.
3M™ Nextel™ AF-20 Fabric is engineered for demanding high-temperature applications where excellent mechanical strength, thermal stability, flexibility, and flame resistance are essential. Its medium-weight 5 Harness Satin construction provides an effective balance of structural integrity, drapeability, and thermal barrier performance.
The fabric is suitable for furnace curtains, thermal barriers, flexible seals, gaskets, refractory assemblies, heat shields, expansion joints, and Ceramic Matrix Composite reinforcement. Its low air permeability, excellent oxidation resistance, chemical stability, and electrical insulation properties make it suitable for severe industrial and aerospace thermal environments.
