OSNABRÜCK, Germany — February 21, 2017 — Footwear manufacturers looking to produce high grip outsoles with good wet slip resistance properties have a new soft thermoplastic polyurethane (TPU) at their disposal – AVALON® 50 AHG TPU from Huntsman.
Delivering a new level of slip resistance for a soft TPU, AVALON® 50 AHG TPU is a suitable replacement for rubber in a variety of outsole applications. Softer than most standard TPU grades, this innovative polyester-based material has a nominal shore hardness of 50A but can offer slip resistance properties on a par with vulcanized rubber.
Providing outstanding anti-slip performance on both wet and dry surfaces, AVALON® 50 AHG TPU enables footwear manufacturers to make soft, thin, high definition, high grip, non-marking parts in a variety of colors.
Appropriate for use in almost all footwear applications, AVALON® 50 AHG TPU is particularly well suited to the production of safety footwear. Oil and petrol resistant, it has excellent electro-static discharge properties and complies with ISO 13287 – the international benchmark for testing slip resistance in protective and personal equipment.
Alongside its physical performance properties, AVALON® 50 AHG TPU also has a number of processing advantages. Easy to use, it has excellent fluidity – meaning standard injection molding cycle times can be achieved. Demolding is also very straightforward. AVALON® 50 AHG TPU is also suitable for the production of dual density footwear on carousel machines in combination with innovative DALTOPED® polyurethane midsole systems.
Alfons Tremml, Commercial Manager at Huntsman Polyurethanes, said: “We knew, from speaking to our footwear customers, that there was real demand for a soft TPU grade that could deliver comparable slip resistance properties to rubber. Combining the benefits of a TPU with a soft feel, and substantially improved levels of wet slip resistance, AVALON® 50 AHG TPU is designed to satisfy that need. During our in-house slip resistance tests, AVALON® 50 AHG TPU performed up to 30% better than reference materials, which were created using identical molds and evaluated under exactly the same trial conditions. This step forward in grip and wet slip resistance will make AVALON® 50 AHG TPU an attractive proposition for outsole production across a range of footwear applications.”
The development of AVALON® 50 AHG TPU increases the range of polyurethane-based solutions that Huntsman can offer manufacturers creating safety shoes, casual unit soles and footwear for sports and lifestyle applications. AVALON® 50 AHG TPU is part of an extensive portfolio of products that Huntsman has developed to satisfy the design and production requirements of modern footwear manufacturers.
