Hyundai Petrochemical Co., Ltd.

Linear Low Density Polyethylene

SEETEC LLDPE

Product Description and Applications

SEETEC LLDPE is produced incorporating the technologies of DSM's compact Solution Process and UCC's gas Phase Process. The advance in production technology enables us to develop products of superior properties in transparency, gloss, durability hardness, heat sealability at low temperatures & high tensile strength. Furthermore, adding co-monomers such as Butene-I, Hexene-I & Octene-I.
