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 |
