POE ExxonMobil 3000

POE ExxonMobil 3000 is a high‑elasticity ethylene‑octene copolymer (C8) with narrow molecular‑weight distribution. Featuring ultra‑low density, broad MFR range, balanced weather resistance, low‑temperature toughness and good processability, it is suitable for high‑demand applications.

Main Applications

Films & Packaging: Cast film, blown film, laminated film, packaging films. Automotive Industry: Modified for components such as bumpers, fenders, instrument panels and pads. Wires & Cables: Insulation layers, sheaths. Daily‑use & Industrial Products: Home appliance housings, sporting goods, toys, rubber hoses, conveyor belts.

Physical Properties

Property	Test Standard	Typical Value	Unit	Comparative Advantages
Density	D792	0.875	g/cm³	12% lighter than TPE
MFR (190℃/2.16 kg)	D1238	5.0 (Grade 3040)	g/10 min	20% better flowability than comparable POE
Tensile Strength	D638	10.5	MPa	150% higher than EVA
Elongation at Break	D638	＞850	%	Resistant to repeated tensile fatigue
Hardness (Shore A)	D2240	82	Shore A	Balanced flexibility and support performance
Vicat Softening Point	D1525	63	°C	Better temperature resistance than PVC
Dielectric Strength	D149	38	kV/mm	Key indicator for cable insulation
Environmental Stress‑Cracking Resistance	D1693	＞1000	h	Excellent chemical‑resistance performance

Injection‑Molding Process

Parameter	Range	Optimization Suggestions
Barrel Temperature	160‑200℃	Segmented temperature control: lower rear section by 10℃ to prevent degradation
Mold Temperature	30‑50℃	Flow marks can be eliminated above 40℃
Injection Pressure	60‑100 MPa	High‑speed injection improves surface gloss
Back Pressure	0.3‑0.7 MPa	Insufficient back pressure results in poor venting

Extrusion / Blown‑Film Process

Parameter	Range	Failure Risk Avoidance
Screw L/D Ratio	28:1‑32:1	Melt fracture occurs at ratio of 4.0
Winding Tension	10‑15 N/cm	Excessive tension causes uneven tightness of film roll
