What is EBA BA-HIGH?
EBA BA-HIGH is EBA in the BA-HIGH grade — very soft, low-melting elastomeric grade for high filler loading, impact modification and tack-critical adhesives. EBA BA-HIGH has a tensile strength of 5 MPa (0.725 ksi), weaker than 82% of polymer grades. Elongation at break is 850% and the elastic modulus is 0.01 GPa (0.002 Msi). EBA BA-HIGH has a density of 0.94 g/cm³ (0.0338 lb/in³), lighter than 77% of polymer grades. Its glass-transition temperature is -52°C (-62 °F).

Working with EBA BA-HIGH
Is EBA easy to machine?
Not a machining material — soft and tacky; cut film/sheet with hot knife or die, chill before slitting.
Can EBA be welded?
Excellent heat, impulse and hot-air/extrusion welding; seal initiation typically 20–40 °C below the grade's melting point.
Can EBA be formed, bent or molded?
Processes on standard LDPE equipment (blown/cast film, extrusion coating, injection) at 150–230 °C melt; dry pellets are hygroscopically inert but high-BA grades need cooled, anti-block-treated handling to avoid pellet blocking.
What surface finishes work on EBA?
Low surface energy — corona or flame treatment to ≥38 dyn/cm before printing, laminating or adhesive bonding; no paint adhesion without pretreatment.

EBA BA-HIGH — frequently asked
What is EBA BA-HIGH used for?
EBA BA-HIGH is typically used for wire and cable insulation, hot-melt adhesive formulations, flexible film blends and impact modification of polyolefins. In short: flexible at low temperature; runs on LDPE equipment; hot-melt adhesive base.
What is the tensile strength of EBA BA-HIGH?
EBA BA-HIGH has a typical tensile strength of 5 MPa (0.725 ksi) — weaker than 82% of polymer grades. Strength varies by condition: see the 5 listed tempers.
Is EBA BA-HIGH easy to machine?
Not especially — machinability is rated poor (15/100, worse than 99% of polymer grades). Not a machining material — soft and tacky; cut film/sheet with hot knife or die, chill before slitting.
Can EBA BA-HIGH be welded?
Yes — weldability is rated excellent (92/100). Excellent heat, impulse and hot-air/extrusion welding; seal initiation typically 20–40 °C below the grade's melting point.
What surface finishes work on EBA BA-HIGH?
Low surface energy — corona or flame treatment to ≥38 dyn/cm before printing, laminating or adhesive bonding; no paint adhesion without pretreatment.
Can EBA BA-HIGH be formed, bent or molded?
Processes on standard LDPE equipment (blown/cast film, extrusion coating, injection) at 150–230 °C melt; dry pellets are hygroscopically inert but high-BA grades need cooled, anti-block-treated handling to avoid pellet blocking.
What is the maximum service temperature of EBA BA-HIGH?
EBA BA-HIGH is rated for continuous use to about 60°C (140 °F), and briefly to 90°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
