Milan, Italy – A shoe designed by the School of Footwear Design and Technology Politecnico Calzaturiero using BASF technology will be showcased at SIMAC - a trade exhibition targeting footwear and leathergoods producers.
The shoe combines different PU and TPU materials, BASF said in a press release.
BASF will also present additions to its portfolio of polyurethane-based footwear processes and material at the event - the SIMAC International Exhibition of Machines and Technologies for Footwear and Leathergoods Industries - which runs from 25-27 February, 2015.
Footwear experts will outline the company’s range of Elastopan PU systems along with the modifications to increase extreme frost resistance before being tested against Russian and Canadian standards.
The Germany-based firm’s Elastollan TPU – a material that instigated adidas’ Boost range of mid-sole-cushioned shoes - as previously reported at utech-polyurethane.com – will also be showcased.
The manufacture of Elastopan and Elastollan is based on renewable raw materials and according to the press release the company’s “bio-based TPU or PU system [is] derived from sebacic acid (dedicated approach) and/or the new mass balance approach.”
The latter approach involves “substitution of fossil raw materials by renewable during the manufacturing of basic chemicals at BASF.”
“The bio-based amount of raw material is then allocated mathematically to the corresponding product. This allows to save fossil resources, to reduce greenhouse gases and guarantees the established chemical and mechanical properties of the existing systems,” the press release added.
