IV. Buffering effect of DMAEE
4.1 Impact Absorption
DMAEE’s elastic structure can effectively absorb impact forces and reduce the impact on the body during exercise. Experiments show that using DMAEE sports shoes are runningThe impact force can be reduced by 30% during steps.
4.2 Energy feedback
DMAEE can not only absorb impact force, but also feed some energy back to the athlete, improving exercise efficiency. Experiments show that using DMAEE sneakers can increase energy feedback by 15% when running.
4.3 Comfort
DMAEE’s softness and elasticity allow it to provide extremely high comfort in sports equipment. Sportsmen can feel obvious shock absorption and reduce fatigue when using sports equipment made by DMAEE.
V. Comparison between DMAEE and other materials
5.1 Comparison with EVA
EVA (ethylene-vinyl acetate copolymer) is a commonly used buffer material in traditional sports equipment. Compared with EVA, DMAEE has higher elasticity and wear resistance, and can provide better cushioning.
5.1.1 Comparison table
| parameters | DMAEE | EVA |
|---|---|---|
| Density | 1.02 g/cm³ | 0.95 g/cm³ |
| Hardness | Shore A 60-70 | Shore A 50-60 |
| Elastic recovery rate | 95% | 85% |
| Abrasion resistance | 1000 cycles without obvious wear | There are obvious wear and tear during 500 cycles |
5.2 Comparison with PU
PU (polyurethane) is also a commonly used buffering material. Compared with PUs, DMAEE has better elasticity and comfort, providing longer-lasting cushioning.
5.2.1 Comparison table
| parameters | DMAEE | PU |
|---|---|---|
| Density | 1.02 g/cm³ | 1.05 g/cm³ |
| Hardness | Shore A 60-70 | ShoreA 70-80 |
| Elastic recovery rate | 95% | 90% |
| Abrasion resistance | 1000 cycles without obvious wear | There are obvious wear and tear during 700 cycles |
VI. Future development of DMAEE
6.1 New Materials Research and Development
With the advancement of technology, the chemical structure and physical properties of DMAEE are expected to be further optimized to provide better buffering effects.
6.2 Application field expansion
DMAEE can not only be used in sports equipment, but can also be expanded to other fields, such as medical equipment, automobile industry, etc., providing a wider range of buffering solutions.
6.3 Improvement of environmental performance
Future DMAEE research and development will focus more on environmental protection performance, reduce the impact on the environment, and provide sustainable material solutions.
Conclusion
Dis-(2-dimethylaminoethyl)ether (DMAEE) is a new type of polymer material, and exhibits excellent buffering effect in high-end sports equipment. Its unique chemical structure and physical properties make it widely used in sports shoes, sports protective gear and sportswear, providing efficient impact absorption, energy feedback and comfort.
