Luran® 368 R Crystal Clear

Product description:

General-purpose grade with well-balanced properties, suitable for injection moulding and extrusion.Especially for
applications where highest transparency and low natural colour is required.

Physical form and storage:

Luran® is supplied as cylindrical or lenticular pellets. The bulk density is approx. 0.55-0.65 g/cm³.
Standard pack: 25 kg PE sack, palletized and film-secured. PE bags should not be stored outside. Subject to agreement,
other means of packing are possible, e.g. 1000 kg bulk containers (flexible IBCs or intermediate bulk big bag containers);
shipping by road tanker can be arranged. Luran® pellets can be stored for prolonged periods in dry areas subject to
normal temperature control without any changes in mechanical properties. However, for sensitive colors storage over
some years can cause some color change. Under poor storage conditions, Luran absorbs moisture, which can be
removed again by drying. Packs stored in cold areas should be brought to ambient temperature before opening, to prevent
condensation on the pellets.

Product safety:

Given appropriate processing of the products and suitable ventilation measures in production areas, no adverse effects on
the health of process operators have been found. Workplace limits for styrene, alpha-methylstyrene and acrylonitrile, as
given in the national listings applicable, must be adhered to.
The values currently applicable in Germany under TRGS 900 (issue of October, 2002) for maximum workplace
concentrations are as follows. Styrene: 20 ml/m³ = 86 mg/m³; alpha-methylstyrene: 100 ml/m³ = 480 mg/m³; acrylonitrile: 3
ml/m³ = 7 mg/m³. Appendix I of Directive 67/548/EWG and TRGS 905 (issue of October,2002) classify acrylonitrile in
carcinogenic category II (substances which should be regarded as carcinogenic in humans).
Experience has shown that during appropriate processing of Luran with suitable ventilation the values obtained are well
below the limits mentioned above. TRGS 402 (Germany) can be used for determining and assessing the concentrations of
hazardous substances in the air within working areas.
Inhalation of gaseous degradation products, such as those which may arise on severe overheating of the material or
during pumped evacuation, must be avoided. Further information can be found in our Luran safety data sheets. These can
be downloaded from the Plastics Portal, www.plasticsportal.net.
