What is EEA FR-ATH?
EEA FR-ATH is EEA in the FR-ATH grade — use for low-smoke zero-halogen cable jackets and sheathing needing UL 94 V-0 and high LOI; stiffness rises and elongation drops sharply. EEA FR-ATH has a yield strength of 9 MPa (1.31 ksi) and a tensile strength of 11 MPa (1.6 ksi) — weaker than 92% of polymer grades. Elongation at break is 160% and the elastic modulus is 0.3 GPa (0.0435 Msi). EEA FR-ATH has a density of 1.5 g/cm³ (0.0542 lb/in³), heavier than 88% of polymer grades. Its glass-transition temperature is -50°C (-58 °F).
Advantages
- Conducts heat well — 0.45 W/m·K (0.26 BTU/hr·ft·°F), better than 97% of polymer grades
- Low embodied carbon — 2.5 kg CO₂/kg, better than 91% of polymer grades
- Low moisture uptake — 0.05%, better than 84% of polymer grades
Limitations
- Difficult to machine — 25/100, worse than 93% of polymer grades
- Low strength — 9 MPa (1.31 ksi), worse than 92% of polymer grades
- Heavy — 1.5 g/cm³ (0.0542 lb/in³), worse than 88% of polymer grades

Working with EEA FR-ATH
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 FR-ATH — frequently asked
What is EEA FR-ATH used for?
EEA FR-ATH 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 FR-ATH?
EEA FR-ATH has a typical yield strength of 9 MPa (1.31 ksi) and a tensile strength of 11 MPa (1.6 ksi) — weaker than 92% of polymer grades. Strength varies by condition: see the 6 listed tempers.
Is EEA FR-ATH easy to machine?
Not especially — machinability is rated poor (25/100, worse than 93% of polymer grades). Effectively unmachinable — too soft and gummy; use die-cutting, water-jet or cryogenic grinding instead of turning/milling.
Can EEA FR-ATH be welded?
Yes — weldability is rated very good (70/100). 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 FR-ATH?
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 FR-ATH be formed, bent or molded?

What is the maximum service temperature of EEA FR-ATH?
EEA FR-ATH 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.
