描述
VESTAMID L2124 BK 9.7507 is a black, high-viscosity, plasticized polyamide 12 compound manufactured by Evonik Operations GmbH. It is specifically designed for extrusion of flexible tubing and hoses, with particular emphasis on oil and petrochemical applications.
The grade is positioned as a PA12-P high-viscosity extrusion material. The plasticized PA12 matrix gives finished tubing greater flexibility than rigid unplasticized PA12, while the high melt viscosity provides the melt strength needed to maintain stable tube geometry after the material exits the extrusion die.
Evonik describes VESTAMID L2124 BK 9.7507 as suitable for tubing according to DIN 73 378, Type PA 12-PHL. This makes the grade relevant for technical tube systems where a recognized PA12 tubing classification is required.
One of the major advantages of this material is dimensional control during pipe extrusion. High melt viscosity helps the extrudate maintain its outside diameter and wall thickness before final cooling and calibration.
The PA12 base also absorbs relatively little moisture. Published water absorption is approximately 1.3%, while humidity absorption is approximately 0.5%. This helps parts and tubing made from VESTAMID L2124 BK 9.7507 maintain dimensions and mechanical behavior when environmental humidity changes.
Impact resistance is another important strength. Unnotched Charpy specimens are reported as no break at both 23°C and -30°C. The dry notched Charpy value at 23°C is approximately 150 kJ/m², showing the very tough and ductile nature of this plasticized PA12-P.
The material also has a low coefficient of friction and good resistance to oils, fuels and many industrial chemicals. Current product data includes resistance information for acids, bases, alcohols, hydrocarbons, motor oil, diesel, brake fluid and other media.

Why Choose VESTAMID L2124 BK 9.7507?
The main reason to choose VESTAMID L2124 BK 9.7507 is its balance of flexibility, extrusion stability and chemical resistance.
Flexible tube extrusion requires sufficient melt strength. A material that is too low in viscosity may sag or lose geometry before calibration. The high melt viscosity of L2124 helps support more stable tube dimensions after the die.
Plasticization is equally important. The resulting tubing is more flexible and more suitable for hose-like applications than rigid unplasticized PA12.
PA12 also offers a major moisture advantage. Because it absorbs relatively little water, dimensions and mechanical properties change less with humidity than many conventional polyamides.
For oil and petrochemical environments, chemical resistance is a critical selection factor. Current product data for VESTAMID L2124 BK 9.7507 includes exposure to standard fuels, diesel, motor oil, hydrocarbons, alcohols, brake fluid and several aqueous chemical solutions.
This combination makes the grade a strong candidate for flexible technical tubing where durability, chemical resistance and reliable extrusion behavior are required together.

The material is supplied in moisture-proof packaging and is ready for processing when the packaging remains intact. If pellets absorb moisture after prolonged exposure to ambient air, drying should follow Evonik’s general VESTAMID processing recommendations.
For precision tubing, die design, calibration, vacuum level, cooling-water temperature and haul-off speed should be optimized together to maintain outside diameter and wall thickness.
Inside original, undamaged packaging, the published shelf life is at least two years when stored dry at temperatures not exceeding 30°C.
