BASF showing new PU & TPU portfolio at A+A 2015
October 27, 2015 - Germany
BASF is presenting its new polyurethane (PU) and thermoplastic polyurethane (TPU) portfolio for work and safety shoes at the A+A 2015, which runs from October 27-30, 2015 in hall 5, stand K32.
According to a BASF press release, the world’s first expanded thermoplastic polyurethane (E-TPU) - Infinergy is now being used for the first time in safety shoes.
The closed-cell, elastic particle foam features low density, high elasticity, high abrasion resistance, high tensile strength and good long-term durability over a wide temperature range along with good chemical resistance.
“Testing of the rebound elasticity in accordance with ISO 8307 and DIN 53512 demonstrates that Infinergy achieves a rebound height of more than 55 per cent,” it stated.
This puts it well ahead of comparable foams such as expanded polypropylene (EPP) at 30 per cent, ethylene vinyl acetate (EVA) at 37 per cent and expanded polyethylene (EPE) at 50 per cent.
“Infinergy does not lose its high resilience even with continuous use, making it the ideal material for midsoles in safety shoes,” the German speciality chemicals producer added.
In Elastopan Light Safe, BASF offers another low-density system, which is water-blown polyurethane and is extremely antistatic with low density.
“Midsoles made of this new material are up to 40 per cent lighter than standard PU systems for midsoles in safety shoes and therefore provide greater comfort,” it explained.
BASF further added that it can be used in combination with TPU or rubber outer soles to produce a dual-density sole that meets ISO standard EN20344:2011.
BASF offers a PU system family under the name Elastopan Extreme Frost specially designed for very cold weather conditions.
In contrast to standard systems, soles made of this material exhibit a flexural strength at minus 45°C of more than 50,000 cycles in the Canadian Ross flex test and more than 8,000 cycles under Russian GOST conditions.
Other core properties include high slip resistance on wet and icy surfaces, low abrasion and high absorption. (AR)
