VESTAMID® E – Polyamide 12 elastomers
elastic and in great form
PA 12 elastomers, the most important subgroup of polyamide elastomers, belong to the increasingly important material class of thermoplastic elastomers (TPE). Thanks to their outstanding properties they are indispensable in a large number of applications.
The PA elastomers are block copolymers consisting of PA 12 segments and polyether segments (polyether block amides or PEBAs). Products rich in PA 12 have the basic properties of that polymer. With increasing polyether content the elastomer character becomes more marked: The polymers are more flexible and have higher cold impact strength.
Compared with competitive thermoplastic elastomers, VESTAMID® E compounds are distinguished particularly by the following properties:
good resistance to chemicals and solvents
ease of processing, coloring, and overmolding
very easily decorated by heat transfer printing
excellent low-temperature impact strength
hardness and flexibility can be varied over wide ranges
high elasticity and good resilience
only slight temperature dependence of mechanical properties
free from volatile or leaching plasticizers
VESTAMID® E compounds are suitable for precision injection moldings, such as noiseless gears and functional elements of sports shoes, as well as for high-performance extrusion components like paint spray hoses, vacuum brake booster lines, and high-quality decorative films. We can provide you with unstabilized or heat- and light-stabilized material, according to your requirements.
Evonik has developed a transparent VESTAMID® polyamide elastomer for the manufacture of high-quality high-tech sports shoe soles.
