Accelerate processing with new Therban® AT!
New Therban® for improved processability
With its new Therban® AT grade, research scientists at LANXESS have achieved a breakthrough in process technology resulting in outstanding benefits for both processing and product properties.
Through a unique process, a linear low Mooney Therban® has been developed that avoids problems typically encountered during the mastication process.
Characteristics of new Therban® AT A 3404:
- 34% ACN
- 39 Mooney ML 1+4 (100 °C)
- Fully saturated (RDB <0.9%)
- Narrow molecular weight distribution leading to good retention of physical properties
* HNBR: 34% ACN / 70 Mooney ML 1+4 (100 °C)
Better flow, faster mold filling and shorter cycle times with Therban® AT
In comparison to regular HNBR grades, the low Mooney viscosity of new Therban® AT leads to better mixing at lower temperatures and therefore to overall cost reduction. Rheovulcameter testing (opposite page) shows the beneficial effect of the significantly improved flow for injection molding. The use of Therban® AT may reduce mold filling cycle times by up to 50%. Alternatively, lower injection pressure or lower temperature can be applied. Extrusion rates can be increased by up to 40%. Benefits can also be observed for compression molding and transfer molding.
Improved sealing force retention with new Therban® AT
Due to the low Mooney viscosity of new Therban® AT, the use of plasticizers can be reduced or - particularly for crucial compounds - even completely omitted. Thus significantly improved sealing force retention upon aging is achieved. Discover the advantages of new Therban® AT as the raw material of choice, either applied alone or in a blend with another standard or specialty Therban® grade including LT, HT, ART and XT types!
