Abstract
Embodiments of the invention relate to method and an additive for a PLA article comprising at least one acrylic impact modifier between 10 and 80 weight % of the total weight of the additive; and at least one vinyl acetate ethylene copolymer (EVA) having ≧12 Wt % vinyl acetate, the EVA between 5 and 50 weight % of the additive; and at least one PLA carrier resin between 5 and 50 weight % of the total weight of the additive.
Claims26
An additive for a PLA article consisting of:
- at least one acrylic impact modifier between 10 and 80 weight % of the total weight of the additive;
- and
- at least one ethylene vinyl acetate copolymer (EVA) having between 12 and 40 weight % vinyl acetate, the EVA between 5 and 50 weight % of the additive;
- and at least one PLA carrier resin between 5 and 50 weight % of the total weight of the additive;
- and optionally a dye, pigment, or coloring agent.
An additive for a PLA article consisting of:
- at least one polylactic acid polymer (PLA) between 10 and 40 weight % of the total weight of the additive;
- at least one acrylic impact modifier between 10 and 80 weight % of the total weight of the additive;
- and
- at least one ethylene vinyl acetate copolymer (EVA) having between 12 and 40 weight % vinyl acetate, the ethylene vinyl acetate copolymer between 10 and 20 weight % of the additive;
- and optionally a dye, pigment, or coloring agent.
A polylactic acid polymer (PLA) sheet, the sheet consisting of:
- at least one PLA between 90 and 99 weight % of the total weight of the sheet;
- and
- an additive between 1 and 10 weight % of the total weight of the sheet, the additive consisting of:
- at least one acrylic impact modifier between 10 and 80 weight % of the total weight of the additive;
- and
- at least one ethylene vinyl acetate copolymer (EVA) having between 12 and 40 wt. % vinyl acetate, the EVA between 10 and 50 weight % of the additive;
- at least one PLA carrier resin between 10 and 50 weight % of the additive;
- and
- optionally a dye, pigment, or coloring agent.
A polylactic acid polymer (PLA) sheet, the sheet consisting of:
- at least one PLA between 90 and 98 weight % of the total weight of the sheet;
- and
- an additive between 2 and 10 weight % of the total weight of the sheet, the additive comprising:
- at least one acrylic impact modifier between 10 and 90 weight % of the total weight of the additive;
- at least one ethylene vinyl acetate copolymer (EVA) having vinyl acetate content between 12 and 40 weight % of the copolymer, the EVA between 5 and 50 weight % of the additive;
- at least one PLA carrier resin between 5 and 50 weight % of the additive;
- and
- optionally a dye, pigment, or coloring agent.
A polylactic acid polymer (PLA) sheet, the sheet consisting of:
- at least one PLA between 90 and 98 weight % of the total weight of the sheet;
- at least one acrylic impact modifier between 1.5 and 2.5 weight % of the total weight of the sheet;
- at least one ethylene vinyl acetate copolymer having-vinyl acetate content between 12 and 40 weight %, the ethylene vinyl acetate copolymer being between 0.2 and 0.3 weight % of the sheet;
- and
- optionally a dye, pigment, or coloring agent.
