Westlake EMAC® SA2413 Ethylene Methyl Acrylate Copolymer  (discontinued **)
Categories: Polymer; Film; Thermoplastic; Ethylene Methyl Acrylate; Ethylene-Methyl Acrylate Copolymer, Film Grade

Material Notes: EMAC® SA2413 is an ethylene methyl acrylate copolymer with 16.5% MA designed for blown film. The high slip and antiblock loading in SA2413 provides for easier handling of films and the low C.O.F. needed in many applications. The high compatibility of this resin makes it ideal as an impact modifier and compatibilizer. Application/Uses: Medical films- Flexible packaging- Seal layer- Quiet films, batch inclusion films- Compatibilizer, impact modifier. Key Attributes: Good adhesion to or compatibility with various polymers- Good heat and RF sealing- High slip and antiblock for low C.O.F.- Soft, flexible, tough without plasticizers.

EMAC resins adhere to and are compatible with a wide range of materials including paper, polyolefins, oriented polyolefins, polyesters, ionomers, PVC, unplasticized PVC and other polar polymers. For use as heat seal layer, adhesive layer, or modifier for cost/performance enhancement. They are soft, pliable and tough at ambient and freezing temperatures and exhibit excellent ESCR. These polymers exhibit high solids fillability and compatibility with a wide range of polymers, facilitating their uses as bases for all-purpose concentrates for addition to a wide spectrum of polymers. They process like LDPE. FDA This product has some 21 CFR clearances.

Samples tested at 23°C and 50% RH.
