n-pentane is one of the main products of our company, finely rectified from the petroleum light dydrocarbon.The n-pentane can be used as desorption agents for molecular sieve dewaxing technique. Mixed with iso-pentane in various proportions, it can meet the standards of different foaming demands, and a highly efficient foaming agent for EPS. With the high purity, low sulphur content and no olefin, it will be the right choice for desorption agents and foaming agents.
