Westlake EMAC® SP2409 20% EMA Copolymer

Technical Datasheet | Supplied by Westlake Chemical
Westlake EMAC� SP2409 is a 20% EMA copolymer designed for extrusion coating, tie-layers, and extrusions where flexibility, compatibility, low heat seal temperatures, or a high coefficient of friction are required. SP2409 provides excellent adhesion to polyolefins, polyesters, and other polymers while providing outstanding low temperature performance. Key attributes of SP2409 include: good heat & RF sealing, low temperature toughness, and a high coefficient of friction. It is soft, flexible, and tough without plasticizers. Its applications include: extrusion coating, flexible packaging, tie-layers, compatibilizer, heat seal layer, and high C.O.F. non-skid surfaces. This resin grade complies with 21 CFR 177.1340. 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. They are made 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. This facilitates their use as bases for all-purpose concentrates for addition to a wide spectrum of polymers. They process like LDPE.
