描述
VESTAMID LX9012 is a high-viscosity, heat- and light-stabilized polyamide 12 compound manufactured by Evonik Operations GmbH for transparent decorative and sports applications. It is especially developed for extrusion and co-extrusion of ski upper films and decorative films, while decoration on the underside of injection-molded sports shoe soles is another established application.
The most important characteristic of VESTAMID LX9012 is the combination of PA12 toughness with an attractive transparent appearance. Films made from this grade are described by Evonik as having high transparency, good screen printability, good sublimation printing performance, outstanding scratch resistance and excellent impact strength at low temperatures.
This combination is valuable in visible decorative components. A ski upper film or decorative surface must maintain its appearance while also resisting scratching, bending, cold impact and environmental exposure. VESTAMID LX9012 was developed around exactly this requirement profile.
The semi-crystalline PA12 matrix absorbs only a small amount of water. Published data lists approximately 1.5% water absorption and 0.8% humidity absorption. Low moisture uptake helps molded and extruded products maintain dimensional stability and relatively consistent mechanical behavior as environmental humidity changes.
PA12 also offers a naturally low coefficient of friction and good chemical resistance. Current product information lists resistance to multiple acids, bases and alcohols, including dilute acetic acid, citric acid solution, sodium hydroxide solutions, ammonium hydroxide, isopropyl alcohol, methanol and ethanol under published test conditions.
Mechanical toughness remains strong at low temperature. Current grade data reports no break in unnotched Charpy impact testing at both 23°C and -30°C, with notched Charpy values of approximately 13 kJ/m² at 23°C and 15 kJ/m² at -30°C.
The grade is supplied as cylindrical pellets in moisture-proof packaging and can be processed by film extrusion, profile extrusion and injection molding, depending on the specific product design.

Why Choose VESTAMID LX9012?
The primary reason to choose VESTAMID LX9012 is the combination of appearance and durability.
Many transparent decorative polymers provide good clarity but may not offer the cold impact strength, scratch resistance or chemical resistance required for demanding sports products. PA12 provides a stronger engineering-property profile while still supporting attractive transparent surfaces.
The grade also offers multiple decoration methods. Screen printing and sublimation printing allow designers to create graphics, logos and complex color effects for ski upper films and sports shoe components.
Low-temperature impact strength is particularly important for winter sports. Ski components can experience mechanical shock at temperatures well below room temperature. The published no-break unnotched Charpy result at -30°C supports this application profile.
Scratch resistance helps maintain the appearance of decorative films during transportation, assembly and use. Meanwhile, low moisture absorption reduces the risk of humidity-related dimensional changes.
Finally, the combination of film extrusion, profile extrusion and injection molding provides processors with flexibility when the same material family is needed across several decorative component designs.
Processing Guidelines for VESTAMID LX9012
VESTAMID LX9012 can be processed by film extrusion, profile extrusion and injection molding.
Evonik’s current processing guidance for LX9012 gives a recommended processing temperature range of approximately:
| Processing Parameter | Recommended Value |
|---|---|
| General Processing Temperature | 200–240°C |
| Published Test Melt Temperature | 240°C |
| Published Test Mold Temperature | 80°C |
| Primary Processes | Film Extrusion, Profile Extrusion |
| Additional Process | Injection Molding |
| Supply Form | Cylindrical pellets / granules |
| Packaging | Moisture-proof packaging |
For film extrusion, actual barrel-temperature profile, die temperature, line speed, chill-roll temperature, draw ratio and film thickness should be optimized for the specific extrusion line.
For injection molding, the published 240°C melt temperature and 80°C mold temperature provide a useful reference point, while the actual settings should be adjusted for part thickness, flow length and required surface quality.
VESTAMID compounds are supplied dry in moisture-proof packaging. Material from intact original packaging is generally ready for processing. If pellets are exposed to ambient humidity for an extended period, drying should follow Evonik’s general VESTAMID processing recommendations.
Inside original and undamaged packaging, VESTAMID LX9012 has a published shelf life of at least two years when stored in dry rooms at temperatures not exceeding 30°C.
For transparent film applications, clean material handling is especially important. Contamination, degraded polymer or excessive residence time can affect clarity and surface appearance.
