What is EEA LOWEA?
EEA LOWEA is EEA in the LOWEA grade — pick when more stiffness, higher melting point and better heat resistance are needed while keeping LDPE-like processing. EEA LOWEA has a yield strength of 9 MPa (1.31 ksi) and a tensile strength of 16 MPa (2.32 ksi) — weaker than 92% of polymer grades. Elongation at break is 600% and the elastic modulus is 0.09 GPa (0.0131 Msi). EEA LOWEA has a density of 0.93 g/cm³ (0.0335 lb/in³), lighter than 79% of polymer grades. Its glass-transition temperature is -50°C (-58 °F).

Working with EEA LOWEA
Is EEA easy to machine?
Effectively unmachinable — too soft and gummy; use die-cutting, water-jet or cryogenic grinding instead of turning/milling.
Can EEA be welded?
Excellent hot-plate, impulse, hot-air and extrusion welding; also heat-seals to LDPE, EVA and itself at low sealing temperatures.
Can EEA be formed, bent or molded?
Extrudes and injection moulds like LDPE at 150–230 °C melt (never above ~250 °C, where ester groups degrade); needs low mould temperature and generous shrinkage allowance (1–2.5 %).
What surface finishes work on EEA?
Low surface energy — corona or flame treat before printing/painting; the polar EA groups still give better ink and adhesive bonding than plain PE.
EEA chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

EEA LOWEA — frequently asked
What is EEA LOWEA used for?
EEA LOWEA is typically used for wire and cable jacketing, hot melt adhesive formulations, impact modifier for polyolefins, flexible tubing and film and asphalt/bitumen modifier. In short: flexible polar polyolefin; tough at low temperature; adhesion-grade PE modifier.
What is the yield strength of EEA LOWEA?
EEA LOWEA has a typical yield strength of 9 MPa (1.31 ksi) and a tensile strength of 16 MPa (2.32 ksi) — weaker than 92% of polymer grades. Strength varies by condition: see the 6 listed tempers.
Is EEA LOWEA easy to machine?
Not especially — machinability is rated poor (20/100, worse than 97% of polymer grades). Effectively unmachinable — too soft and gummy; use die-cutting, water-jet or cryogenic grinding instead of turning/milling.
Can EEA LOWEA be welded?
Yes — weldability is rated excellent (90/100). Excellent hot-plate, impulse, hot-air and extrusion welding; also heat-seals to LDPE, EVA and itself at low sealing temperatures.
What surface finishes work on EEA LOWEA?
Low surface energy — corona or flame treat before printing/painting; the polar EA groups still give better ink and adhesive bonding than plain PE.
Can EEA LOWEA be formed, bent or molded?
Extrudes and injection moulds like LDPE at 150–230 °C melt (never above ~250 °C, where ester groups degrade); needs low mould temperature and generous shrinkage allowance (1–2.5 %).
What is the maximum service temperature of EEA LOWEA?
EEA LOWEA is rated for continuous use to about 75°C (167 °F), and briefly to 90°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
