DOW™ 640I Low Density Polyethylene Resin

A Low Density Polyethylene (LDPE), barefoot general purpose liner resin for thin gauge applications requiring good drawdown and excellent toughness.

用途:

  • Hygiene films (backsheet)
  • Blown and cast film extrusion

优势:

  • Fast conversion speed
  • Low gauges
  • Provides good bubble stability in backsheet production
  • Provides draw resonace stability in backsheet production
  • Optimum gauge range: 0.8-3.0 mil
