描述
VESTAMID NRG 1902 BK is a black, high-viscosity, plasticized and impact-modified polyamide 12 compound from Evonik Operations GmbH developed for the extrusion of flexible tubing and hoses, especially for oil and petrochemical applications.
The current Evonik product information places VESTAMID NRG 1902 BK in the Sustainable, Energy, Oil and Gas sector and emphasizes its combination of high viscosity, impact modification, heat stabilization and light stabilization.
A central advantage of the grade is its extrusion behavior. Evonik states that VESTAMID NRG 1902 BK offers easy processing and good dimensional control during pipe extrusion, especially when processing large pipe diameters. This is important because larger flexible tubes and pipes require sufficient melt strength to control sag, ovality and wall-thickness variation as the hot extrudate leaves the die.
The material is plasticized, which provides flexibility, while impact modification improves toughness under dynamic loading and handling. The high-viscosity design supports stable pipe geometry during extrusion.
The current grade-specific datasheet also lists resistance to hydrolysis / hot water, UV / light / weathering, and oil / fuels. These resistance characteristics make the material especially relevant for industrial piping and hose systems exposed to demanding fluids or outdoor environments.
PA12 has another important advantage over more moisture-sensitive polyamides: its properties change relatively little as ambient humidity changes. Evonik specifically notes that this is due to the low moisture absorption of polyamide 12.
The semi-crystalline material is also characterized by exceptional impact strength, a low coefficient of sliding friction and good general chemical resistance.
Current dry mechanical data shows a tensile modulus of approximately 385 MPa, tensile strength of approximately 43 MPa, stress at 50% strain of approximately 27 MPa, stress at break of approximately 43 MPa, and nominal strain at break of approximately 220%.
These values confirm that VESTAMID NRG 1902 BK is not a rigid structural PA12. It is a highly ductile flexible extrusion material designed to tolerate large deformation while maintaining meaningful mechanical strength.
The recommended extrusion processing temperature is 220°C to 250°C.
The material is supplied ready for use in moisture-proof bags. Inside original and undamaged packaging, the product has a shelf life of at least two years when stored dry at temperatures not exceeding 30°C.

Grade-Specific Data Not Publicly Exposed
The current open two-page product information does not publish a complete density, MVR, melting point, HDT, Vicat or electrical-property table for this exact grade.
For those values, use the latest Evonik grade-specific TDS rather than copying numerical data from NRG 1001 or another VESTAMID PA12 product.
This avoids mixing similar but non-identical formulations.

Why Choose VESTAMID NRG 1902 BK?
The main reason to choose VESTAMID NRG 1902 BK is its combination of flexibility, impact resistance and dimensional control during demanding pipe extrusion.
Large-diameter flexible pipe is difficult to process. As diameter and wall thickness increase, gravitational sag, uneven cooling and dimensional distortion become more difficult to control.
A high-viscosity material provides greater melt strength after the polymer exits the die. Evonik specifically identifies good dimensional control during large-diameter pipe extrusion as a strength of VESTAMID NRG 1902 BK.
At the same time, the resin is plasticized and impact modified. This prevents the material from becoming excessively rigid and supports the flexibility required for tubing and hose applications.
The current mechanical data reinforces that positioning. A tensile modulus around 385 MPa is much lower than unplasticized PA12 grades, while 220% nominal strain at break provides substantial deformation capability.
Resistance to oil and fuels is another important selection factor. Energy and petrochemical tubing can be exposed to hydrocarbon media for extended periods. The current datasheet specifically lists oil/fuel resistance.
Hydrolysis and hot-water resistance expand the service range further, while heat, light and weathering stabilization support outdoor or thermally demanding environments.
The black formulation also provides a ready-colored grade for technical pipe and hose systems where black identification or appearance is required.
Processing Guidelines for VESTAMID NRG 1902 BK
VESTAMID NRG 1902 BK is designed for extrusion of flexible tubing, hoses and pipe.
The current Evonik product information provides a clear recommended processing temperature:
| Processing Parameter | Published Guidance |
|---|---|
| Primary Process | Extrusion |
| Recommended Extrusion Temperature | 220–250°C |
| Main Products | Flexible tubing, hoses, pipe |
| Delivery Form | Pellets / Granules |
| Packaging | Moisture-Proof Bags |
| Shelf Life | At least 2 years at ≤30°C in original undamaged packaging |
The current datasheet also provides standardized injection-molded specimen conditions:
| Test-Specimen Parameter | Published Value |
|---|---|
| Injection Molding Melt Temperature | 290°C |
| Mold Temperature | 60°C |
| Injection Velocity | 200 mm/s |
These 290°C / 60°C / 200 mm/s values are test-specimen production conditions, not the recommended pipe-extrusion recipe.
For commercial extrusion, use 220–250°C as the manufacturer-recommended starting window and optimize:
- Barrel-temperature profile
- Adapter and die temperature
- Screw speed
- Melt pressure
- Line speed
- Pipe diameter
- Wall thickness
- Die swell
- Vacuum sizing
- Cooling conditions
- Ovality
- Surface quality
- Residence time
Large-diameter production should pay particular attention to cooling uniformity, melt sag and dimensional control.
Because the material is supplied in moisture-proof bags, intact original packaging helps protect processing consistency. Opened material should be resealed promptly and kept dry.

| Color | Black | Natural Color |
| Viscosity | High | High |
| Primary Market | Oil & petrochemical flexible tubing / hoses | Oil & gas flexible pipe / large-diameter extrusion |
| Heat / Light Stabilized | Yes | Yes |
| Large-Diameter Control | Explicitly highlighted | Explicitly highlighted |
| Recommended Extrusion Temperature | 220–250°C | 220–250°C |
| Tensile Modulus | Approx. 385 MPa dry | Approx. 370 MPa |
| Nominal Strain at Break | 220% dry | Approx. 200% dry / 300% conditioned |
| Main Selection Difference | Black oil/petrochemical tubing and hose grade | Natural NRG grade with broader published flexible-pipe dataset |
Both grades are high-viscosity, flexible PA12 materials for demanding extrusion.
Choose VESTAMID NRG 1902 BK when the black grade is specified for oil/petrochemical tubing, hose or pipe service.
Choose VESTAMID NRG 1001 when that exact natural-color grade or its broader flexible-pipe qualification dataset is required.
The two grades should not be treated as automatically interchangeable without checking the customer specification and latest Evonik documentation.
