Perlite's low thermal conductivity and insulating properties make it a suitable additive for nonwoven fabrics used in applications where thermal insulation is important. It helps improve the fabric's insulation capabilities, making it ideal for products like thermal blankets, fire-resistant barriers, and insulating wraps.

Perlite can be used in nonwoven fabrics designed for absorbent products like diapers, feminine hygiene products, and medical dressings. Its absorbent properties help improve the fabric's capacity to retain fluids and maintain a dry surface. Perlite's porous structure can contribute to sound absorption properties when added to nonwoven fabrics. This is beneficial in applications like acoustic panels and automotive interior materials.

Perlite can enhance the abrasion resistance of nonwoven fabrics, making them more durable and long-lasting. This is valuable in applications where the fabric is subjected to wear and tear, such as upholstery and industrial textiles.
