Terluran ® GP-22 natural

Product description

"WORLD GRADE"

Easy flow, general purpose injection moulding grade with high resistance to impact and heat distortion; intended for a wide range of applications, particularly in the housings sector.

Applications

Household : washing machine, vacuum cleaners; refrigerator parts;

Office equipment ; monitor, printer housings, computers, copier parts ; toys

Physical form and storage

Terluran is delivered in the form of cylindrical or spherical pellets. The bulk density of the pellets is from 0.55 to 0.65 g/cm³. Values may differ for special grades. Standard Packaging unit: 25 kg paper bag. In addition, delivery in larger units of up to 1000 kg (IBC = Intermediate Bulk Container) or silo trucks can be arranged.

In dry areas with normal temperature control, Terluran pellets can be stored for

relatively long periods of time without any change in mechanical properties.

With unstable colours, however, storage over a number of years can give rise to some change in colour. Under poor storage conditions, Terluran absorbs moisture, but this can be removed by drying. Product safety

No adverse effects on the health of processing personnel have been observed where the products are correctly processed and the production areas are suitably ventilated. For styrene, alpha-methylstyrene, acrylonitrile, and 1,3-butadiene the maximum allowable workplace concentrations must be observed according to the pertaining national regulations. In Germany, the following limit values are valid (Nov 1999): styrene, MAK-value: 20 ml/m³ = 85 mg/m³; alpha-methylstyrene, MAK-value: 100 ml/m³ = 480 mg/m³; acrylonitrile, TRK-value: 3 ml/m³ = 7 mg/m³ and 1,3-butadiene, TRK-value: 5 ml/m³ = 11

mg/m³. According to EU directive 67/548/EEC, Annex I (Nov 1999), acrylonitrile and 1,3-butadiene are classified as carcinogenic, category 2 ( 'substances which should be regarded as if they are carcinogenic to man'). Experience has shown that when Terluran is processed correctly with appropriate ventilation, the levels are far below the limits mentioned above. Inhalation of the vapours of degradation products which can arise on severe overheating of the materials or during purging out should be avoided. Our Terluran safety data sheets give further

information.
