The shelf life of polyester nonwoven fabrics is mainly affected by environmental conditions, material stability, and packaging methods.

Industry Background and Market Demand The increasing complexity of electrical systems, coupled with stringent safety regulations, has driven demand for advanced fire-resistant materials in industrial and commercial applications. Electrical equipment, from transformers to circuit boards, generates heat and is susceptible to short circuits, which can lead to catastrophic fires. Traditional materials like woven fabrics or plastics often fail to meet modern fire safety standards due to their limited thermal resistance and structural instability under extreme conditions.

Industry Background and Market Demand Electrical installations require materials that ensure safety, durability, and compliance with stringent fire safety regulations. Flame-retardant (FR) polyester fiber nonwoven fabrics have emerged as a critical component in electrical insulation, cable wrapping, and protective barriers due to their ability to resist ignition, slow flame spread, and minimize toxic smoke emissions.

Introduction The electrical insulation industry relies on materials that ensure safety, efficiency, and durability in high-voltage and high-temperature environments. Among the various options available, nonwoven fabrics have gained prominence due to their unique structural and functional advantages. This article explores the role of nonwoven fabrics in electrical insulation, examining their properties, manufacturing processes, key performance factors, and emerging trends in the field.

Industry Background and Market Demand The global insulation materials market is projected to exceed $80 billion by 2027, driven by stringent energy efficiency regulations and sustainability mandates. Traditional materials like fiberglass, mineral wool, and polystyrene have dominated the industry for decades. However, polyester fiber nonwoven fabrics are gaining traction due to their versatility, lower environmental impact, and performance adaptability.
