描述
VESTAMID LX9039 NC is an unmodified, medium-viscosity polyamide 12 from Evonik Operations GmbH formulated without stabilizers and without processing aids. This makes the grade different from most standard PA12 compounds, which often contain heat stabilizers, lubricants, mold-release agents, UV packages or other additives to optimize processing and long-term performance.
Evonik positions VESTAMID LX9039 NC for special cases where the absence of additives is desirable or where conventional processing aids could interfere with the final application. The material is supplied as spherical granules in moisture-proof packaging and is ready for processing when the packaging has been handled correctly.
The key reason to choose VESTAMID LX9039 NC is therefore formulation purity rather than a specialized additive package. It is useful when the processor wants the inherent properties of PA12 but needs greater control over what is—and is not—present in the resin.
PA12 itself is valued for low moisture absorption, strong dimensional stability, good impact resistance, low friction and broad chemical resistance. Because water uptake is much lower than in many shorter-chain nylons, dimensional and mechanical changes caused by changing ambient humidity are relatively limited.
Publicly indexed material data for VESTAMID LX9039 NC reports approximately 0.7% moisture absorption and a glass-transition temperature around 39°C. The same public database shows heat-deflection values in the 50–110°C range, depending on test load.
Another important characteristic is medium viscosity. This gives the grade a useful balance between flow and melt strength. It is not positioned as an ultra-low-viscosity fast-flow grade and not as a highly viscous tube-extrusion resin. Instead, it serves as a relatively neutral PA12 base for special processing requirements.
The additive-free concept also makes VESTAMID LX9039 NC relevant in filament and brushware development. Patent literature specifically identifies VESTAMID LX9039 as a PA12 source in recyclable bristle-product concepts, while Evonik has highlighted the related eCO LX9039 BBM100 grade for applications such as toothbrush filaments.

| Additive-Sensitive Application Potential | Suitable when lubricants, mold-release agents or stabilizers are undesirable |
The most important point is that VESTAMID LX9039 NC is intentionally simpler than many performance-modified PA12 grades.
Typical Applications for VESTAMID LX9039 NC
VESTAMID LX9039 NC is best considered for applications where additive control is important.
| Application Area | Typical Use |
|---|---|
| Special Additive-Sensitive Components | Parts where conventional stabilizers or processing aids may interfere |
| Filament Development | PA12 filaments requiring a clean, unmodified base resin |
| Brushware / Bristle Concepts | Documented PA12 use in recyclable bristle-product development |
| Engineered Injection-Molded Parts | Components requiring medium-viscosity natural PA12 |
| Special Compound Development | Base resin for carefully controlled downstream formulation work |
| Laboratory / Development Programs | Material studies where additive effects need to be minimized |
| Precision Technical Parts | Applications benefiting from PA12 dimensional stability |
| Special Extrusion Projects | Applications where a neutral PA12 formulation is preferred |
Because VESTAMID LX9039 NC deliberately contains no stabilizers or processing aids, it should not automatically replace a heat-stabilized, UV-stabilized, lubricated or easy-release PA12 grade without checking the actual service and processing requirements.
Typical Properties of VESTAMID LX9039 NC
Physical & Rheological Properties
| Property | Publicly Available Reference |
|---|---|
| Material Family | PA12 |
| Color | Natural |
| Viscosity Classification | Medium Viscosity |
| Form | Spherical Granules |
| Moisture Absorption | Approx. 0.7% |
| Additive Package | No stabilizers / no processing aids |
| Pigmentation | May affect property values |
Current open public indexes confirm that the full VESTAMID LX9039 NC dataset includes density, water absorption, MVR, molding shrinkage and viscosity-number data, but not all exact numerical values and test conditions are exposed without accessing the complete TDS database. For customer-facing qualification, the current official TDS should be used for those exact figures.
Mechanical Properties
Current indexed data for VESTAMID LX9039 NC shows the following published ranges across dry/conditioned or different test conditions:
| Property | Publicly Indexed Range |
|---|---|
| Tensile Strength | Approx. 31–50 MPa |
| Tensile Strain | Approx. 5–260% |
| Flexural Strength | Approx. 32–58 MPa |
| Impact Properties | Available in current full TDS |
| Shore Hardness | Available in current full TDS |
These ranges show why the test condition matters. PA12 mechanical values can differ between dry and conditioned specimens, and a product page should not mix values from different conditioning states as if they were one single result.
Thermal Properties
| Property | Publicly Available Reference |
|---|---|
| Glass Transition Temperature | Approx. 39°C |
| Heat Deflection Temperature | Approx. 50–110°C, depending on test load |
| Melting Temperature | Available in current full TDS |
| Vicat Softening Temperature | Available in current full TDS |
VESTAMID LX9039 NC does not contain a heat-stabilizer package. That is intentional and should be considered when evaluating continuous elevated-temperature exposure.
Electrical Properties
Current material databases list numerical data for:
- Relative permittivity
- Dissipation factor
- Surface resistivity
- Volume resistivity
- Dielectric strength
For applications where these values are critical, use the current grade-specific TDS rather than transferring values from another VESTAMID PA12 grade.
Why Choose VESTAMID LX9039 NC?
The main reason to choose VESTAMID LX9039 NC is control over additives.
Most commercial engineering-plastic compounds are optimized with several additives. These can improve processing, heat aging, UV resistance, demolding, friction or color stability. In many applications that is beneficial.
However, certain projects require the opposite approach. A lubricant may interfere with bonding or coating. A mold-release additive may affect surface energy. A stabilizer system may be undesirable in a tightly controlled formulation. A research project may also need an unmodified base polymer so that the effect of another additive can be evaluated accurately.
VESTAMID LX9039 NC is designed for these special situations.
At the same time, the grade still provides the inherent benefits of PA12. Low moisture absorption helps maintain dimensions. The semi-crystalline polymer structure provides useful chemical resistance and toughness. Medium viscosity gives a practical balance between flow and melt strength.
This makes the material especially attractive when the processor does not want a heavily optimized compound but still requires a high-performance engineering polyamide.
Processing Guidelines for VESTAMID LX9039 NC
Evonik supplies VESTAMID LX9039 NC as spherical granules in moisture-proof packaging and describes the grade as ready for processing.
Evonik’s general VESTAMID processing guide states that drying is normally required only if the packaging has been damaged or the material has remained exposed to ambient air for an extended period.
For unplasticized PA12, Evonik recommends:
| Processing Item | General PA12 Guidance |
|---|---|
| Drying Temperature | 80–100°C |
| Dehumidified-Air Drying Time | 2–4 hours |
| Target Moisture after Drying | <0.1% |
| General PA12 Mold Temperature | 30–100°C |
| Preferred Material Handling | Keep opened material tightly sealed and minimize air exposure |
Evonik also notes that the machine should be thoroughly cleaned before production because contamination with incompatible polymers can significantly reduce weld-line and mechanical strength.
Because VESTAMID LX9039 NC contains no stabilizers or processing aids, processing should avoid unnecessary thermal stress and excessive residence time. The actual melt-temperature window should be taken from the latest grade-specific TDS or optimized with Evonik technical support rather than copied from a different PA12 grade.
For extrusion, Evonik’s general guidance states that temperature settings depend strongly on the resin and type of extrudate. The first heating zone is typically set above the melting point, followed by an increasing profile toward the extruder tip, while adapter and die temperatures may be adjusted to control melt stability.
VESTAMID LX9039 NC vs. VESTAMID LX9042 NC
| Feature | VESTAMID LX9039 NC | VESTAMID LX9042 NC |

| Primary Positioning | Additive-sensitive special applications | Fast-cycle injection molding |
| Demolding Optimization | No dedicated release package | Strong easy-release positioning |
| Main Selection Reason | Minimal additive formulation | Efficient short-cycle molding |
Choose VESTAMID LX9039 NC when absence of stabilizers and processing aids is an important part of the material requirement.
Choose VESTAMID LX9042 NC when efficient injection molding, easy release and short cycle time are more important than additive-free formulation.
VESTAMID LX9039 NC vs. VESTAMID eCO LX9039 BBM100
Evonik also offers VESTAMID eCO LX9039 BBM100, which is built around the same unmodified, medium-viscosity, additive-free PA12 positioning but uses Evonik’s mass-balance sustainability approach.
The eCO version is especially relevant when a customer needs both the LX9039 formulation concept and improved sustainability metrics. Evonik reports that eCO LX9039 BBM100 uses 100% biobased carbon in a mass-balanced approach and has a published carbon footprint of approximately 2.7 kg CO₂e/kg.
Choose the standard VESTAMID LX9039 NC when the conventional grade is specified.
Choose the eCO version when the project includes renewable-feedstock, carbon-footprint or sustainability targets and the corresponding qualification is acceptable.
