Cotton Flocks

 Cotton Flocks


Yields lightweight, thixotropic filling compouds
For epoxy, polyester, and polyurethane resins

Manufacture of light, nonrun adhesive, pourable moulding compound and coupler coatings for mould construction, using a mixture of 50 volume percent glass fibre cuttings and 50 volume percent cotton flocks.

Cotton flocks are use for enhanced dimensional stability in moulded products, increased impact and abrasion resistance. Good adhesion to epoxy, polyester, and polyurethane resins as well as to rubber compounds. Resistance to many chemicals and alkalines.

Appearance: white flock, fiber length: approx. 350 µm (typical 150–500 µm), fiber width 10–25 µm (1–3 Denier), specific gravity 1.5 g/cm³, melting charakteristic - chars at 250 °F (120 °C), decomposes at 300 °F (150 °C), tensile strenght up to 120,000 psi (ca. 800 N/mm²).
Insoluble in Acetone, DMF or 40 % NaOH, water uptake approx. 0.3 g water taken up per g cotton flock.
