The first aspect is covered by resistance of the person-shoe-floor system as defined shoe. the requirement for antistatic footwear. For product in EN 61340-5-1 is less than 3.5 × 107 Ω i.e. Warning: ESD shoes are unsuitable for use by protection, the ESD-capability of safety shoes is also 35 M Ω. electricians and for working on live electrical required. equipment.

The latter has This combines the benefits of both materials: the on. This creates a lightweight sole which can easily the great advantage that it allows the use of two exceptional heat resistance of rubber and the adapt to the floor characteristics. different materials with different properties. For comfortable damping characteristics of polyurethane. instance, the sole tread may be made of rubber but The special advantage of the single-layer sole is that Rubber Nitrile rubber (Perbunan) Extremely hard-wearing, heat resistant for short Very hard-wearing. Heat resistant up to 220°C. periods up to 300 °C; good resistance to cuts and Very good non-slip characteristics and excellent abrasion. Resistant to fuel, oil, microbes and a wide resistance to acids and alkalis. variety of chemicals. Heavier than PU and TPU and also somewhat less flexible when cold. Polyurethane (PU) Thermoplastic polyurethane (TPU) Heat resistant up to 130°C and flexible in cold down Similar to PU soles, but overall significantly better to -30°C. Resistant to oil and fuel, a wide variety of performance. Less abrasion means the soles last chemicals, and microbes. longer, and also increases the non-slip properties. Lighter than rubber soles. Good shock absorption In addition they offer even greater flexibility and characteristics and pleasant to wear. optimised resistance to cold. 378
