Technological Innovations Bring Perfect Shoe Soles

Today's football shoes are all high-tech sports equipment and are part of the trendy sportswear.

In sports and leisure industries, the need to create sales performance forces manufacturers to unremittingly develop new capabilities of equipment in previous experience and fashion levels and constantly reducing the cycle.

Every new season will create new challenges for developers and sports equipment.

Modern polymers make it possible to tailor sports shoes for individual specific sports.

To make light, elastic and shock resistant soles, a multi-purpose and economical solution is to use the complete foaming materials that are easy to process, such as the Bayflex (R) products developed by the Bayer Material Sciences Corp (BayerMaterialScience).

The sole of modern sports shoes is made of these materials. The midsole is not easy to deform, prevent hydrolysis, and has a high degree of "active shock absorption ability", that is, they are very gentle on the joints and spine of athletes.

Another special property of polymer is that it can produce honeycomb core plate and gently pition to the surface of closed cell.

One of the main advantages is the combination of lightweight and good mechanical properties of sole.

Density and hardness can be adapted to a wide range of special needs, from soft to cushioning, or elastic sandwich like wood as hard as the sole.

Football shoes represent a great challenge to polymer materials.

Football shoes must be able to reach the target by shock absorption and dispersion pressure, dustproof and waterproof, without damaging the joints, ligaments and muscles.

These conditions can be achieved by thermoplastic polyurethane (TPU), such as Desmopan (R), which combines the advantages of rubber and thermoplastic materials BayerMaterialScience.

The simple release technology developed by BayerMaterialScience, a new shoe technology, makes it easier for shoes and soles to detached from the model, which is usually difficult to achieve due to the good adhesion of polyurethane.

The release material of polybasic hydroxyl compounds ensures the smoothness of the molds, and less than 50% of the release material is more necessary than conventional applications.

At the same time, the apparently improved surface minimizes the formation of bubbles. It produces visually attractive soles with high value, extinction and dry rubber appearance.

However, polyols, such as isocyanates, a structural unit of polyurethane, can not only achieve these effects.

Based on stamping technology, polyhydroxylated compounds produce less waste, larger shoe sole production and continuous processing.

From the bottom up, the appearance of shoe sole is very special. The use of catalyst has created a very uniform shape for polyhydroxyl compounds, which has brought great benefits to processing.

The conventional method not only forms the expected long-chain polyether polyols, but also interconnects two or more terminals with isocyanates, and produces fewer byproducts during processing.

These only act on one side of isocyanate, or nothing.

As a result, some of the standard polyhydroxylated compounds left debris or thread in the polyurethane system, which eventually reduced the elasticity of the plastics.

In order to achieve the density required for cross linking of polyhydroxyl compounds and isocyanates in polymers, polyhydroxyl compounds that are more than required are usually incorporated into polyurethane mixtures.

Polyhydroxyl compounds are produced by stamping technology, and on the other hand, less debris is dropped, so that the required crosslinking can be achieved at lower doses of polyhydroxyl compounds.

Stamping technology produces lightweight, resilient, wear-resistant, economical products, which show less wear even in continuous wear and resistance to moisture and bacteria.

Because of these characteristics, this material is better and lighter than the commonly used materials of sports shoes EVA and rubber and polyester polyurethanes.

The considerable reduction of viscosity in stamping preparation also makes the processing program simpler.

The demoulding time is shortened because the smallest cross connection occurs very quickly in the hardening process.

Obviously, the results are: the production cycle is faster.

Innovative technology not only helps paved the way for athletes to achieve maximum performance.

It also provides the sports equipment manufacturers with the ability to improve economic efficiency, production speed and processing efficiency.
