ELEVATE® EF510 is a 10% vinyl acetate copolymer designed for flexible packaging that requires excellent toughness, low temperature brittleness, and heat sealing characteristics. It also has high melt strength which imparts good bubble stability during film processing. Test specimens for blown film: nominal thickness 2.0 mils; blow up ratio 2.5:1, die gap 35 mils at 50% relative humidity and 23°C. Information provided by Westlake Chemical. |
