Ulsan, Korea – BASF's polyurethane aerogel insulation material, Slentex, has been used for the first time in an industrial application.
The material is being used as insulation for almost 400m2 of pipework, flanges and valves at the company's manufacturing plant in Ulsan.
Site manager Sun Jung Yoo said BASF had chosen the material to help reduce pipe maintenance costs caused by corrosion under insulation. ‘Thanks to Slentex's nano-porous aerogel structure and water vapour diffusion properties and hydrophobic surface, there is a reduction of condensation of the pipes,’ he said.
The PU aerogel has 19mW/mK thermal conductivity, and can provide the same insulation properties as a traditional material such as perlite with a 30-40% thinner layer of insulation, BASF said.
Slentex could be used in cryogenic applications and shipping, according to Rohit Ghosh, head of business management construction in the Asia Pacific region. 'We have installed Slentex in a a residential product that Hokushu adopted for external thermal insulation in its new Passive house in Japan,' he said.
