描述
VESTAMID L2170 OR E20005 is a high-viscosity, heat- and light-stabilized polyamide 12 resin manufactured by Evonik Operations GmbH. It was developed especially for extrusion of cable sheathings and can also be used for semi-finished products such as tubes, rods, sheets and profiles.
The material is supplied in an orange formulation and is identified in Evonik product literature as PA12, EHL, 22-010. Compared with general-purpose PA12 grades, VESTAMID L2170 OR E20005 places stronger emphasis on light and weathering resistance for demanding outdoor cable applications.
One of its most important advantages is the low coefficient of friction associated with semi-crystalline PA12. This low sliding friction helps reduce resistance when cables are pulled through ducts, conduits or protective channels.
The material also has a tough and smooth surface. Evonik specifically describes cable sheathing made from the L2170 family as helping protect directly buried cables against attack by termites and rodents. Official Evonik cable literature also identifies L2170 as a PA12 grade used for underground cable protection where toughness, weathering resistance and resistance to pests are important.
Low water absorption is another key characteristic. Published data for VESTAMID L2170 OR E20005 gives approximately 1.6% water absorption and 0.8% humidity absorption. As a result, the material retains good dimensional stability when ambient humidity changes.
The grade also combines high toughness with good chemical resistance. These properties are important for outdoor cable systems, underground installation and industrial extrusion applications where the polymer may contact water, oils, fuels or other environmental media.
In addition to wire and cable extrusion, current product data lists injection molding, pipe/tube extrusion, profile extrusion and sheet extrusion as possible processing methods.

Why Choose VESTAMID L2170 OR E20005?
The main reason to choose VESTAMID L2170 OR E20005 is its combination of cable-sheathing processability, weathering resistance and mechanical protection.
Outdoor and underground cables face several simultaneous challenges. They can be exposed to moisture, temperature changes, sunlight, abrasion and chemical contamination. In some regions, termites and rodents can also damage cable jackets.
Evonik developed the L2170 family specifically for this environment. The material is highly light stabilized, and official VESTAMID literature describes L2170 as a UV-stable and termite-resistant cable-sheathing grade.
The PA12 surface also has low friction. This reduces drag when the cable is installed in ducts and can make long cable pulls easier compared with higher-friction materials.
The high viscosity helps maintain stable cable-jacket geometry during extrusion, while the high toughness helps resist mechanical damage after installation.
Low water absorption further supports dimensional stability, and broad chemical resistance helps the sheathing tolerate demanding outdoor and underground environments.
For customers seeking a high-viscosity PA12 specifically optimized around cable-protection requirements, VESTAMID L2170 OR E20005 is therefore more targeted than a general tube-extrusion PA12.
Processing Guidelines for VESTAMID L2170 OR E20005
VESTAMID L2170 OR E20005 is listed for wire/cable extrusion, pipe/tube extrusion, profile extrusion, sheet extrusion and injection molding.
The current product data provides the following ISO test-specimen conditions:
| Processing Item | Published Condition |
|---|---|
| Primary Processing | Wire / Cable Extrusion |
| Other Processes | Pipe / Tube, Profile and Sheet Extrusion; Injection Molding |
| ISO Test Melt Temperature | 240°C |
| ISO Test Mold Temperature | 60°C |
| ISO Test Injection Velocity | 200 mm/s |
| Supply Condition | Cylindrical granules in moisture-proof packaging |
| Storage | Dry storage at ≤30°C in original undamaged packaging |
These ISO molding values are test-specimen conditions and should not be treated as a universal cable-extrusion temperature profile.
For cable extrusion, the barrel-temperature profile, die temperature, line speed, draw-down ratio and cooling system should be optimized for the actual cable diameter, jacket thickness and production line.
Evonik states that VESTAMID compounds are delivered dry in moisture-proof packaging. Material from intact packaging does not normally require additional drying before processing.
For opened or damaged packaging, Evonik’s cable-processing guide recommends drying VESTAMID in a desiccant dryer at approximately 90–100°C for a minimum of two hours. A dehumidifying hopper dryer operating around 60–80°C may also be used during processing.
The moisture content of VESTAMID should remain low during extrusion because excess moisture can reduce melt quality and surface appearance.
Inside original and undamaged packaging, VESTAMID L2170 OR E20005 has a published shelf life of at least two years when stored in dry rooms at temperatures not exceeding 30°C.
