* -premium rayon reinforcement General Description Storage, Handling and Processing Cordenka® rayon is a man-made cellulose yarn for technical applications. It consists of multiple continuous filaments. The number of filaments determines the linear density of the yarn, i.e. its thickness (1 dtex = 10-4 g m-1). Usually the yarn has almost no twist (approx. 2-3 t/m) so that the single filaments are aligned in parallel. We can also provide twisted yarns (100 t/m). Furthermore we offer Cordenka® rayon in form of woven fabrics and chopped fibers. • Specified constant properties • Improvement of composite material's ♦ Impact resistance, also at low temperatures • Reinforcement and light weight construction for: ♦ Completely biobased and biodegradable composites ♦ Passenger car tyres, mechanical rubber goods • Vehicle parts, shields, housing for machinery • Acoustic devices, sports equipment • Cordenka® rayon is composed of cellulose. It is both • Storage: Protect CORDENKA® products against heat, cold, moisture, direct solar radiation and extreme climatic fluctuations. • Cutting and dosing: For Cutting and dosing of Cordenka® Rayon we recommend the use of special equipment. If you need assistance for selecting appropriate machinery, please contact us. • Processing: If your process is sensitive to moisture, we recommend drying of Cordenka® rayon for two hours at 105 °C. Alternatively, inline drying at higher temperatures (less than a minute) can be applied. During processing, the temperature should be kept below 200 °C and the exposure time at this temperature should not exceed 20 minutes. • For the compounding of thermoplastic composites it might be useful to add coupling agents. Excellent results in polypropylene can be achieved with MAHPP. Superior recycling suitability: During processing, Cordenka® rayon maintains an excellent level of fiber lengths, resulting in a consistently high level of mechanical properties in
