Footwear synthetic materials

The chemical picture of this modified collagen is not yet complete, but its mixed structural regions already hint at similar new synthetic materials. For the NIH, which has supported this biotechnological research, the hope is that this unique material, with its variable elasticity, will lead to more comfortable and pliable artificial skin. Ultimately, it could also improve the quality of such goods as footwear and radial tires, where softness and toughness are equally desirable. 

Heveaplus MG has a higher polarity than NR and it is usually used as primer for NR solutions to increase the adhesion of PVC and synthetic upper materials in crepe rubber soles in footwear. 

The combination of synthetic carpets, man-made footwear materials and dry, air-conditioned buildings contributes to the creation of static electrical charges building up on people moving about these buildings. Individuals only become aware of the charge if they touch earthed metalwork, such as a stair banister rail, before the static electricity has been dissipated. The effect is a sensation of momentary shock. 

One of the most important methods of assembling shoe components is adhesive bonding. In 1949 polychloroprene adhesives replaced the nitrocellulose solutions that had been introduced in 1906. The almost complete versatility of the polychloroprenes allowed leather, textiles, and other natural substances (until then the only shoe materials) to be supplemented by other materials, such as various rubbers and synthetics, or to be replaced altogether, as in the case of toe puffs, counter stiffeners, or heels. The way was thus opened for an astounding development in fashion and shoemaking techniques. Adhesive-based processes, supported by new machines and equipment, led to new bottom-attachment systems, simplified the production of footwear, and drastically reduced the number of production operations. Since 1970 a position of comparable importance has been reached by polyurethane adhesives. 

Although synthetics are making a name for themselves in the work footwear market, leather is undoubtedly the tried and true upper material found in many work boots — and for good reason. Leather is breathable and a good choice for people who are on their feet for hours at a time. Leather provides a customized fit for each individual because leather molds to the foot... 

Tried and tme materials — leather, mbber and steel — have earned their solid reputation in the work footwear market with years of proven performance. However, their new challengers — synthetics, PU/IPU/ EVA and composite/aluminum — offer their own set of advantages. What s best depends on individual safety and comfort needs the best may be a combination that leverages the best characteristics of each material. [...
