描述
VESTAMID LX9012 T8 is a heat-stabilized and light-resistant polyamide 12 compound from Evonik Operations GmbH developed especially for the extrusion and co-extrusion of ski upper films and decorative films.
The grade combines the engineering performance of semi-crystalline PA12 with the optical and surface properties required for visible sports and lifestyle components. Films produced from VESTAMID LX9012 T8 are described by Evonik as having high transparency, good screen-printing and sublimation-printing capability, outstanding scratch resistance and excellent impact strength at low temperatures.
These properties are especially important for ski upper films. A ski surface must remain visually attractive while being exposed to snow, moisture, abrasion, impact and low temperatures. VESTAMID LX9012 T8 provides a durable PA12 surface that can protect printed designs while maintaining a clean transparent or translucent appearance.
Decoration on the bottom side of injection-molded sports shoe soles is another published application. This allows the material to support visible graphics and decorative effects in products where toughness and scratch resistance are also required.
The semi-crystalline PA12 matrix absorbs only small quantities of water. Published water absorption is approximately 1.5%, while humidity absorption is approximately 0.8%. Low moisture uptake helps products maintain dimensional stability and impact performance as ambient humidity changes.
PA12 also offers a naturally low coefficient of friction and good general chemical resistance. These characteristics help improve the surface durability and handling performance of decorative films and molded sports components.
Current grade data lists both film extrusion and injection molding as processing methods. The grade is supplied as cylindrical granules in moisture-proof packaging and is ready for processing when the packaging remains intact.

Why Choose VESTAMID LX9012 T8?
The main reason to choose VESTAMID LX9012 T8 is the combination of visual quality and mechanical durability.
Many transparent polymers can provide attractive appearance, but decorative sports surfaces also need impact resistance, scratch resistance and reliable performance at low temperatures. Ski products are especially demanding because they combine cold weather, moisture, repeated impact and visible graphics.
The PA12 base gives VESTAMID LX9012 T8 strong toughness while keeping water absorption low. This helps the film remain dimensionally stable and reduces the property changes associated with humidity.
Printing performance is another major advantage. Screen printing and sublimation printing allow manufacturers to place graphics, logos and complex decorative designs under or within the protective film structure.
Scratch resistance helps preserve these graphics during transportation, assembly and end use. The transparent surface can act as both a decorative and protective layer.
Low-temperature impact performance is particularly relevant to skiing. The published notched Charpy value rises from approximately 13 kJ/m² at 23°C to 15 kJ/m² at -30°C, while unnotched specimens remain no-break.
For manufacturers of skis, sports equipment and lifestyle products, VESTAMID LX9012 T8 therefore provides a focused material solution rather than a generic PA12 resin.
Processing Guidelines for VESTAMID LX9012 T8
VESTAMID LX9012 T8 is designed primarily for film extrusion and co-extrusion, while injection molding is also listed in current material data.
The grade-specific public data provides the following reference conditions:
| Processing Parameter | Published Value |
|---|---|
| Primary Process | Film Extrusion / Co-Extrusion |
| Additional Process | Injection Molding |
| MVR Test Condition | 220°C / 10 kg |
| Published Test Melt Temperature | 240°C |
| Published Test Mold Temperature | 80°C |
| Supply Form | Cylindrical pellets / granules |
| Packaging | Moisture-proof packaging |
| Shelf Life | At least 2 years at ≤30°C in original undamaged packaging |
The published 240°C melt temperature and 80°C mold temperature are material-test conditions. They should not be treated as a fixed film-extrusion recipe.
For film extrusion and co-extrusion, barrel temperatures, adapter temperature, die temperature, output rate, draw ratio, chill-roll temperature and final film thickness should be optimized for the specific production line.
Because optical appearance is a major requirement, clean material handling is especially important. Contamination, excessive residence time or thermally degraded polymer can reduce transparency and surface quality.
VESTAMID materials are supplied in moisture-proof packaging. Material from intact packaging is ready for processing. If the pellets have absorbed moisture after prolonged exposure to ambient air, drying should follow Evonik’s general VESTAMID processing recommendations.
Inside original and undamaged packaging, VESTAMID LX9012 T8 has a published shelf life of at least two years when stored dry at temperatures not exceeding 30°C.
