Choosing the Right Product

Goodfellow offers various forms of Kevlar:

Staple Fibers: These short, discrete fibers can be blended with other materials or processed into non-woven fabrics. They provide added strength and durability to composite materials.

Continuous Filament Yarns: Long, continuous strands of Kevlar fibers, commonly used in reinforcement applications such as ropes, cables, and fabrics.

Paper: A thin, flexible sheet made from Kevlar fibers that offers excellent strength, heat resistance, and electrical insulation properties. Used in gaskets, electrical insulation and filtration.

Spun Laced Fabrics: Non-woven fabrics made by interlocking Kevlar fibers using high-pressure water jets. They exhibit high strength, tear resistance, and flexibility, making them suitable for protective clothing and industrial applications.

All our Kevlar products comply with European Directives 2015/863/EU (RoHS 3) and 2000/53/EC (ELV), ensuring their environmental friendliness. Additionally, we hold certifications for ISO 9001, EN 9100, ISO 14001, and ISO 45001, demonstrating our dedication to quality and safety.
