What safety shoes are the most slip-resistant?

     Walking on a smooth road with oil and water, the greater the friction coefficient between the sole and the oily surface, the less likely it is to slip. The editor of the safety shoe manufacturer has found a lot of information, including some experimental studies on the anti-slip property of the sole. In general, slipping is related to the sole material, the sole texture, the contact area between the sole and the ground, and the walking posture. .

The most slip-resistant sole material - natural rubber

At present, safety shoe sole materials are divided into PU (polyurethane), NR (natural rubber), PVC (polyvinyl chloride), EVA (ethylene-vinyl acetate copolymer resin), TPR (rubber-plastic blend thermoplastic elastomer), etc. Natural rubber has good wear resistance, non-slip, and good softness.

PVC has high density, high hardness and good elasticity. TRP has strong cold resistance. EVA multi-slip is the worst. Compared with various materials, natural rubber soles have the best slip resistance. Many safety shoes that claim to have good slip resistance may not have good slip resistance on oily surfaces.

Generally, the soles of common safety shoe manufacturers are generally made of hard rubber. The anti-slip performance is mainly reflected in rough ground environments such as rocky roads, gravel roads, and muddy roads. On smooth surfaces such as marble, the friction between the sole and the ground The force is small, so the slip resistance is not good.

The larger the contact surface, the better the slip resistance

Softer and more slip-resistant sole

The larger the contact area between the sole and the ground, the larger the force area, the larger the friction coefficient, and the less likely it is to slip. For the sole of the same material, the more textures on the sole, the deeper the anti-skid, the better. The finer the texture and the smaller the bumps, the higher the static friction coefficient. Different degrees of hardness of the sole also affect the deformation of the sole.

For softer shoes, the grooves on the bottom line are easy to soften and deform when they are deeply stressed, which can increase some contact area, thereby increasing the friction force. Compared with safety soles with shallow and thick lines, such deformation is relatively small, and thus the contact surface is small. , the friction force is small, so when walking on a smooth oil surface, the safety shoes with soft soles are harder than the soles.
