Cotton Flocks

• Yields light, thixotropic filling compounds
• Very suitable for epoxy, polyester and polyurethane resins as well as rubber compounds
• Insoluble in acetone, dimethylformamide or 40 % NaOH
• Good chemical resistance (including alkalis)
• Very inexpensive

Technical data:
Fiber type: Cotton
Appearance: Flakes
Colour: White
Fiber diameter: 10-25 µm (1-3 denier)
Specific weight: 1.5 g/cm³
Carbonized: at 120 °C
Decomposition: at 150 °C
Fiber length: approx. 350 µm (typically 150-500 µm)
Water absorption: approx. 0.3 g per g of cotton flakes
Bulk density: 4.5 liters of cotton flakes = 1 kg (0.22 g/cm³)
Tensile strength: up to approx. 800 N/mm²

The volume information serves to give a better idea of the delivery quantity. This is the loose bulk quantity. The contents of the container may compact during transportation and storage.

Application:
Production of light, non-running adhesives and free-flowing molding compounds as well as coupling layers in mold making, using a mixture of 50 % by volume glass fiber chips and 50 % by volume cotton flocks.

Cotton flocks increase the dimensional stability as well as the impact and abrasion resistance of the molding materials.
