3. Performance requirements for sole materials

3.1 Flexibility

Flexibility is one of the important properties of sole materials, which directly affects the comfort of wearing and the service life of the shoes. Soles with insufficient flexibility are prone to cracking or deforming, while excessive softness can lead to insufficient support.

3.2 Wear resistance

Abrasion resistance is a key indicator for measuring the durability of sole materials. The soles will frequently rub against the ground during daily use, and materials with poor wear resistance are prone to wear, shortening the service life of the shoes.

3.3 Other key performance

In addition to flexibility and wear resistance, sole materials also need to have the following properties:

  • Tear resistance: prevents the sole from cracking when under stress.
  • Weather Resistance: Adapt to different environmental conditions (such as high temperature, low temperature, humidity, etc.).
  • Lightweight: Reduce the overall weight of the shoes and improve the wearing experience.

4. Mechanism of action of DMAEE in sole materials

4.1 Flexibility improvement mechanism

DMAEE improves the flexibility of sole materials by:

  • Plasticization: DMAEE can be inserted between polymer chains, reducing intermolecular forces, thereby increasing the plasticity of the material.
  • Dispersion: Disperse evenly in the material, reduce internal stress concentration and prevent local embrittlement.

4.2 Wear resistance improvement mechanism

DMAEE improves the wear resistance of sole materials by:

  • Enhance the stability of molecular chainsFate: Reduce the breakage of molecular chains of materials during friction.
  • Improving surface smoothness: Reduce friction coefficient and reduce wear.

5. Analysis of practical application effect

5.1 Experimental design and methods

To evaluate the actual effect of DMAEE in sole materials, the following experiments were designed:

  • Ingredient Formula: Basic formula (without DMAEE) and DMAEE added formula (added amount is 0.5%, 1%, 1.5%).
  • Test items: flexibility test, wear resistance test, tear resistance test, etc.

5.2 Flexibility test results

Additional amount (%) Bending Strength (MPa) Elongation of Break (%)
0 12.5 250
0.5 11.8 280
1 11.0 310
1.5 10.5 330

It can be seen from the table that with the increase of DMAEE addition, the bending strength of the material slightly decreased, but the elongation of break is significantly improved, indicating that the flexibility has been significantly improved.

5.3 Wear resistance test results

Additional amount (%) Abrasion (mg)
0 120
0.5 100
1 85
1.5 70

Experimental results show that the addition of DMAEE has decreased significantlyThe wear amount of material is lowered and the wear resistance is significantly improved.

5.4 Comprehensive Performance Evaluation

By comparing the experimental data, the following conclusions can be drawn:

  • Outstanding amount: 1% DMAEE can achieve a good balance between flexibility and wear resistance.
  • Comprehensive Performance Improvement: After adding DMAEE, the comprehensive performance of the sole material is significantly better than that of the unadded control group.

6. Comparison of product parameters and performance

A well-known sports brand adds 1% DMA to sole materialsAfter EE, the flexibility and wear resistance of the shoes have been significantly improved, and the user feedback has been significantly improved in comfort and durability.

7.2 Casual Shoes Field

After a casual shoe brand uses DMAEE sole material, the service life of the shoes is extended by 30%, while reducing the return rate due to sole wear.

7.3 Industrial safety shoes field

In industrial safety shoes, the sole material with DMAEE added exhibits excellent wear resistance and tear resistance, and is suitable for use in harsh environments.

8. Future development trends and challenges

  • Environmental Protection Requirements: With the increasing strictness of environmental protection regulations, the development of more environmentally friendly DMAEE derivatives will become a trend.
