R&G cotton flakes, bag/ 500 g

Produces lightweight, thixotropic fillers for epoxy, polyester, and polyurethane resins. Application area: manufacturing lightweight, non-flowing adhesives and free-flowing press masses, as well as coupling layers in mold construction, using a mixture of 50 vol.-% glass fiber chips and 50 vol.-% cotton flakes. Cotton flakes enhance dimensional stability as well as impact and abrasion resistance of the molding materials. Very well suited for epoxy, polyester, and polyurethane resins as well as rubber mixtures. Good chemical resistance (including alkalis). Very cost-effective.

Bulk density: 4.5 liters of cotton flakes = 1 kg (0.22 g/cm³). Appearance: white flakes, fiber length: approx. 350 µm (typically 150–500 µm), fiber diameter: 10–25 µm (1–3 Denier), specific weight: 1.5 g/cm³, chars at 120 °C, decomposes at 150 °C, tensile strength up to approx. 800 N/mm². Insoluble in acetone, dimethylformamide, or 40% NaOH, water absorption approx. 0.3 g per g of cotton flakes. The volume indication serves to provide a better understanding of the delivery quantity. This refers to the loose bulk quantity. During transport and storage, the contents may compact.

Safety data sheet: Safety data sheets are required based on the REACH regulation for hazardous substances and mixtures. Cotton flakes are neither hazardous nor a substance or mixture within the meaning of the REACH regulation. It is a product for which, by definition, no safety data sheet can be created.
