描述
VESTAMID LX9043 NC is a semi-crystalline, low-viscosity polyamide 12 molding compound from Evonik Operations GmbH developed for the production of hollow industrial and technical parts by rotational molding.
The current product information describes the grade as a heat-stabilized PA12 molding compound with improved demoldability. This makes it very different from conventional VESTAMID tube-extrusion or injection-molding grades. Its formulation is specifically intended to support hollow-part manufacturing and easier release from the mold.
A key feature of VESTAMID LX9043 NC is its low viscosity. The current grade-specific data lists an MVR of approximately 63 cm³/10 min at 230°C / 5 kg. The relatively high flow helps the material spread and form a uniform polymer layer during processing.
The material also contains a release agent, which supports improved demolding after the part has cooled and crystallized. This is especially useful in rotational molding, where large hollow components can otherwise be difficult to remove from the mold without damage.
Evonik positions the material for industrial and engineering applications requiring hollow plastic products of different sizes. Current characteristics also list thermoforming in addition to rotational molding.
PA12 provides an important advantage in these applications because it absorbs only small amounts of water. VESTAMID LX9043 NC has a published water absorption of approximately 1.5%, while the measured moisture content in the current product information is approximately 0.07 wt.%. As a result, molded components maintain good dimensional stability when ambient humidity changes.
Mechanical performance is also notable. The dry tensile modulus is approximately 1,110 MPa, yield stress is approximately 39 MPa, and the typical nominal strain at break is approximately 344%. This gives the material a useful combination of moderate stiffness and very high ductility.
Impact performance remains strong at low temperature. Unnotched Charpy specimens show no break at both 23°C and -30°C, while notched Charpy impact strength is approximately 5 kJ/m² at 23°C and 4 kJ/m² at -30°C.
The grade is supplied as natural-color cylindrical pellets in moisture-proof packaging, ready for processing. Evonik states that the material has a shelf life of at least two years in original undamaged packaging stored dry at temperatures not exceeding 30°C.

Why Choose VESTAMID LX9043 NC?
The main reason to choose VESTAMID LX9043 NC is its processing profile for hollow PA12 parts.
Rotational molding requires the material to distribute evenly against the mold surface while the mold rotates through the heating cycle. A low-viscosity grade can support better flow and surface coverage than a high-viscosity PA12.
The release-agent package provides an additional advantage after cooling. Improved demoldability can reduce the risk of damage when removing a large hollow part from the tool.
The material also provides the inherent advantages of PA12. Low water absorption supports dimensional stability, while high ductility helps the part tolerate deformation and impact.
The approximately 1,110 MPa tensile modulus provides useful structural stiffness without making the material excessively rigid. At the same time, the typical nominal strain at break of approximately 344% gives substantial deformation capacity.
Low-temperature impact performance is another advantage. Unnotched Charpy specimens show no break at -30°C, which is relevant for outdoor or industrial applications exposed to cold environments.
For processors that need a natural-color, low-viscosity, easy-release PA12 for rotationally molded hollow parts, VESTAMID LX9043 NC is therefore much more application-specific than a standard injection-molding grade.
Processing Guidelines for VESTAMID LX9043 NC
VESTAMID LX9043 NC is primarily characterized for rotational molding and thermoforming.
The current grade-specific product information also publishes the following processing recommendations:
| Processing Parameter | Published Value |
|---|---|
| Pre-Drying Temperature | 70–80°C |
| Pre-Drying Time | 5–12 hours |
| Target Processing Moisture | ≤0.1% |
| Melt Temperature | 210–220°C |
| Mold Temperature | 60–80°C |
| Feed Temperature | 40–60°C |
| Circumferential Speed | 50–200 mm/s |
| Back Pressure | 5–10 MPa |
| Property-Test Melt Temperature | 220°C |
| Property-Test Mold Temperature | 80°C |
These published values provide useful processing references, but rotational-molding cycle conditions still depend strongly on the machine, mold size, wall thickness, heating medium and cooling method.
For rotational molding, the following variables should be optimized together:
- Material charge weight
- Mold geometry
- Heating cycle
- Mold-surface temperature
- Rotation ratio
- Cooling rate
- Target wall thickness
- Venting
- Demolding temperature
- Final dimensional tolerance
Because the grade is supplied as cylindrical pellets, processors should follow their established rotational-molding preparation and feed procedure for the selected equipment.
The material is supplied in moisture-proof packaging. If the original bag remains intact, moisture pickup is minimized. If the material has been exposed to ambient humidity, the published pre-drying recommendation is 70–80°C for 5–12 hours, with a target processing moisture of ≤0.1%.
