3M™ Nextel™ EF-20 Fabric Supplier & Exporter in India
Premium 3M™ Nextel™ EF-20 Fabric
Marshall Packings & Insulations Industries is a trusted supplier and exporter of 3M™ Nextel™ EF-20 Fabric, a high-performance semi-unidirectional structural ceramic fabric manufactured from 3M™ Nextel™ 720 continuous ceramic oxide fiber roving. Designed for demanding high-temperature structural applications, EF-20 Fabric combines outstanding mechanical strength, exceptional creep resistance, low thermal shrinkage, and excellent dimensional stability. It is widely used as a reinforcement material in Ceramic Matrix Composites (CMC), Metal Matrix Composites (MMC), and Polymer Matrix Composites (PMC) for aerospace, fuel cell, and industrial applications.
Unlike conventional woven ceramic fabrics, EF-20 features a plain semi-unidirectional weave with 10,000 denier warp roving and 1,500 denier fill roving, maximizing reinforcement in the primary load direction. The fabric is electrically insulating, chemically resistant, non-hygroscopic, non-oxidizing, and exhibits very low shrinkage after repeated thermal cycling, making it ideal for lightweight structural composite components operating in extreme thermal environments.
3M™ Nextel™ EF-20 Fabric is engineered for directional structural reinforcement in advanced composite applications where high mechanical strength and thermal stability are essential. Its semi-unidirectional construction places the majority of the reinforcing fiber in the warp direction, making it suitable for components subjected to high directional loads.
The combination of 3M™ Nextel™ 720 continuous ceramic oxide fiber, high-denier warp roving, low air permeability, creep resistance, and excellent dimensional stability provides reliable performance in severe thermal environments. EF-20 Fabric is suitable for aerospace, defense, fuel cell, industrial furnace, and advanced composite applications.
