Very low density polyethylene and high density polyethylene blends

Very low density polyethylene and high density polyethylene blends

Blends of very low density polyethylene produced using metallocene catalysts (mVLDPE) and high density polyethylene (HDPE) are disclosed. The polymer blends include a metallocene-catalyzed VLDPE polymer having a density of less than 0.916 g/cm3, the VLDPE polymer preferably being linear and without...

Zusammenfassung:Blends of very low density polyethylene produced using metallocene catalysts (mVLDPE) and high density polyethylene (HDPE) are disclosed. The polymer blends include a metallocene-catalyzed VLDPE polymer having a density of less than 0.916 g/cm3, the VLDPE polymer preferably being linear and without long chain branching, and a HDPE polymer having a density of greater than 0.940 g/cm3. The polymer blends are particularly suitable in blown and cast film applications.
