Product catalog summary

Introduction
Cordenka GmbH & Co. KG provides cellulosic yarns for composites, emphasizing their bio-based and biodegradable nature. These yarns offer excellent resistance to organic solvents, low abrasiveness, and intrinsic reactivity with surrounding matrices. They do not have a glass transition temperature or melting point.

Specifications

Yarn Types: Cordenka® 610F, Super 2, Cordenka® 700, Super 3, Cordenka® MA1, Super 4.
Linear Density: Ranges from 1220 dtex to 2440 dtex.
Breaking Force: Varies from 1257 N to 2485 N.
Breaking Tenacity: Between 682 MPa and 778 MPa.
Elongation at Break: 9.5% to 12.7%.
Modulus: 13.9 GPa to 18.3 GPa.

Make-Up
Yarns are packaged in cylindrical bobbins with varying weights and dimensions. Pallet dimensions are 126/105/110 cm.

Applications
Cordenka® reinforced thermoplastics are suitable for injection molding parts. They significantly improve the Charpy impact behavior of thermoplastics, even at low temperatures.
