VESTAMID® D, the polyamide 612 (PA 612) from Evonik, is the polycondensation product of 1,6-hexamethylenediamine and 1,12-dodecanedioic acid (1,10-decane dicarboxylic acid). Although the carbonamide group concentration is slightly higher than in polyamide 12, it is significantly lower than in polyamide 6 or polyamide 66. VESTAMID® D molded parts therefore have virtually the same valuable properties as VESTAMID® L parts:
The advantages over PA 12 are as follows:
The PA 612 compounds of the VESTAMID® D series are therefore specialties supplementing the extensive product range of the PA 12 compounds of the VESTAMID® L series. The excellent rebound resilience is advantageous in the bristles of toothbrushes, as is the high heat deflection temperature for short-term temperature spikes such as occur, for example, in hydraulic clutch lines in vehicles. This property also makes VESTAMID® D polyamide compounds suitable for plastic-rubber composites, as in door lock casings, housing covers with seals, and seals for spark plug tubes.Details of the product range are available in the information VESTAMID® D polyamide 612 compounds and their characteristics, indication for applications in the information VESTAMID® D compounds and their applications.
