- Polyether Block Amide (PEBA): DIAMID® E / VESTAMID® E
Thermoplastic Elastomer of Polyether Block Copolyamide (PEBA)
DAIAMID® E / VESTAMID® E is a thermoplastic elastomer (TPE) belonging to the PA12 (Polyamide 12) elastomer family. Thanks to its excellent properties, it is an essential material in many applications. Recent developments have introduced aunique flexible foam made from this material, achieving high rebound resilience.
Properties
The PA elastomers are block copolymers consisting of PA12 segments and polyether segments (polyether block amides or PEBAs). Products rich in PA12 have the basic properties of that polymer. With increasing polyether content the elastomercharacter becomes more marked: The polymers are more flexible and have higher cold impact strength.
Compared with competitive thermoplastic elastomers, DAIAMID® E / VESTAMID® E compounds are distinguished particularlyby the following properties:
- low density
- 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
DAIAMID® E / VESTAMID® E compounds are suitable for precision injection moldings, such as noiseless gears and functionalelements of sports shoes, as well as for high-performance extrusion components like paint spray hoses, vacuum brakebooster lines, and high-quality decorative films. We can provide you with unstabilized or heat- and light-stabilized material,according to your requirements. Transparent and high-gloss molding compounds are also available.
High-performance Polymer for Sports Fans
Performance and design are key in sports shoes, whether for soccer, skiing, or hiking. The thermoplastic elastomer polyether block amide (PEBA) meets the highest requirements placed on it—as it has been doing over the last 40 years. As far back as1979 Evonik launched PEBA on the market under the VESTAMID® E brand name.
Freedom of design is very important in the sports goods sector, explains Klaus Hülsmann, Director Sports. “The shoe oftomorrow will look very different from that of today—and our material must be able to meet that challenge.” PEBA is in factvery easily processed, colored, and overmolded. “It’s also important that the material is elastic and virtually indestructible, nomatter how the sportsperson uses it,” adds Hülsmann. Ski or climbing boots made from DAIAMID® E / VESTAMID® E, forexample, are light, waterproof, and wear-resistant, and retain their flexibility in the cold.
New foam with high ball resiliency
The latest development from our polyamide 12 elastomers is a unique flexible foam with a ball resiliency of 73%. Itcomplements the excellent properties of VESTAMID® E PEBA with the low weight of 82 kg/m³ and exceptional comfort. It is notcrosslinked and not plasticized and can be produced as extrusion and injection molded autoclave foam on standard machines.
