描述
VESTAMID LX9057 OR E20081 is a low-viscosity, self-extinguishing polyamide 12 compound from Evonik Operations GmbH containing an efficient halogen-free flame-retardant system.
The grade is designed especially for the electrical, electronics and cable industries, where flame behavior, electrical insulation, dimensional stability, toughness and processing consistency are important at the same time.
Current grade-specific material information classifies VESTAMID LX9057 OR E20081 as PA12 FR(30+40). It is heat stabilized, halogen-free and suitable for both injection molding and wire extrusion coating.
Flame behavior is one of the grade’s defining characteristics. The current Material Data Center datasheet reports V-2 at 0.8 mm and V-2 at 1.5 mm, with a Yellow Card available. The current UL certification for LX9057 OR E20081 also lists V-2 down to 0.40 mm for the orange grade. This provides useful qualification information for thin-wall electrical and cable-related components.
The PA12 base contributes low moisture sensitivity. Published water absorption is approximately 1.8% and humidity absorption approximately 0.8%. Because PA12 absorbs much less water than many shorter-chain polyamides, molded or extruded parts show good dimensional stability as ambient humidity changes.
Mechanical performance remains strong despite the flame-retardant package. Dry tensile modulus is approximately 1,200 MPa, while conditioned modulus is approximately 820 MPa. Dry yield stress is approximately 37 MPa, and nominal strain at break remains above 50% in both dry and conditioned states.
Impact behavior is also useful. Dry unnotched Charpy impact strength at 23°C is approximately 130 kJ/m², while the current -30°C values are approximately 69 kJ/m² dry and 122 kJ/m² conditioned.
The orange E20081 formulation also retains important electrical-insulation performance. Current data lists a dry volume resistivity of approximately 7.4 × 10¹¹ Ω·m, electric strength of approximately 35 kV/mm, and CTI 600.
The material is supplied as cylindrical granules in moisture-proof packaging and has a shelf life of at least two years in original undamaged packaging stored dry at temperatures not exceeding 30°C.

Why Choose VESTAMID LX9057 OR E20081?
The primary reason to choose VESTAMID LX9057 OR E20081 is the balance of halogen-free flame retardancy, electrical insulation and PA12 toughness.
Many flame-retardant engineering plastics become relatively stiff or brittle. LX9057 OR E20081 retains more than 50% nominal strain at break and strong impact performance, making it suitable for parts that must survive assembly, vibration and handling.
Low moisture uptake is another important advantage. Electrical components can suffer dimensional drift when a polymer absorbs water. PA12 helps reduce this problem compared with more hygroscopic polyamides.
The material’s low viscosity also supports processing. In injection molding, good flow can assist filling of thin-wall features. In wire extrusion coating, it helps the melt distribute around the conductor or cable substrate.
Electrical performance is particularly strong for this application class. CTI 600 supports tracking resistance, while 35–36 kV/mm electric strength provides useful dielectric capability.
Finally, the orange E20081 color provides a ready-colored formulation for applications where orange identification is required.
Processing Guidelines for VESTAMID LX9057 OR E20081
VESTAMID LX9057 OR E20081 can be processed by injection molding and coating / wire extrusion coating.
Temperature control is especially important because of the flame-retardant package.
| Processing Parameter | Published Guidance |
|---|---|
| Recommended Melt Temperature | 200–220°C |
| Maximum Melt Temperature | Do not exceed 240°C |
| ISO Test Melt Temperature | 220°C |
| ISO Test Mold Temperature | 80°C |
| ISO Test Injection Velocity | 200 mm/s |
| MVR Test Condition | 220°C / 2.16 kg |
| Primary Processes | Injection Molding, Coating / Wire Extrusion Coating |
| Packaging | Moisture-proof bags |
| Shelf Life | At least 2 years at ≤30°C in original undamaged packaging |
Evonik specifically states that the melt temperature should not exceed 240°C because the compound contains flame retardant. The recommended melt-temperature range is 200–220°C.
For wire extrusion coating, the exact barrel profile, head temperature, die temperature, conductor preheating, line speed and coating thickness should be optimized for the actual equipment and cable construction.
For injection molding, the grade-specific standardized test condition of 220°C melt / 80°C mold / 200 mm/s injection velocity is a useful technical reference.
