SPC Smoothly Makes NEP

Recently, with the cooperation between SPC and Shanghai Research Institute of Petrochemical Technology of Sinopec, the non-heavy ecology polyester (NEP) has been successfully created in the Polyester Business Department of SPC by using new Ti catalyst independently developed by Sinopec, and it has been put into production. Besides, the textile produced with NEP can get the "Eco" ecological textile label from the EU, so as to stand in a leading position among the export of textile and other products influenced by the financial crisis.

N means non-heavy, E means ecology and P means polyester. The NEP product has the same appearance as the traditional polyester product, while it is brighter and more transparent.

In the production process of traditional polyester, the antimony catalyst is used for more than 98% of the polyesters. The polyester produced with the technology of antimony catalyst can meet relevant state standards, so it is safe and eco-friendly. However, as the antimony is a kind of heavy metal, it was successively regarded as the pollutant concerned by the EU and the US with priorities. At present, the EU has put forward the requirement to limit the content of antimony in textile and the use of heavy metals such as antimony, stannum and lead in electrical and electronic machines. The textile which doesn't contain the antimony can be identified through the "ECO-label" (the ecological textile label) in the EU.

Confronted with the people's demand of being more ecological and eco-friendly as well as the influence caused by the financial crisis, by grasping the development trend of the polyester market, SPC has culled proper Ti catalyst to successfully develop new NEP products in continuous polyester devices, with the help of improving the cooperation with scientific research units and the independent innovation technology of Sinopec.
