Product description:

Iso-pentane is one of the main products of our company; they are finely rectified from the petroleum light hydrocarbon. With their high purity, up to 99.9%,low sulphur content and no olefin, they have reached the quality of international standard. The iso-pentane can be the solvent for the catalyst in polyethylene production, foaming agent for EPS and polyurethane foam system, deasphalting solvent, also the important industrial chemicals for the production of isoamylene and isoprene.
