Hyundai Petrochemical Co., Ltd.

Low Density Polyethylene

SEETEC LDPE

Product Description and Applications

SEETEC LDPE is produced in two variances to satisfy requirements. The tubular process produces LDPE of a narrow molecular weight distribution with proper optical & mechanical characteristics which is ideal in the production  of various film extrusions. The autoclave process produces LDPE of a wider molecular distribution with a lower neck-in & a better processability. LDPE developed with the autoclave process provides an optimum medium in the production of injection moldings & in the application of cable & extrusion coatings.
