描述
VESTAMID L1723 BK 9.7624 is a low-viscosity, plasticized polyamide 12 compound from Evonik Operations GmbH. The grade is designed primarily for injection molding and is specifically positioned for strip clips, cable ties and fastening components that require a combination of toughness, flexibility, low friction and dimensional stability.
The material is based on PA12-P and combines the naturally low moisture uptake of polyamide 12 with plasticization and stabilizer technology. As a result, VESTAMID L1723 BK 9.7624 can maintain useful mechanical performance and dimensional consistency when ambient humidity changes.
Another important advantage is its low coefficient of friction. This characteristic is useful for cable ties, clips and fastening elements because it supports smooth assembly, sliding contact and installation while reducing unnecessary friction between the molded component and surrounding parts.
The grade is heat stabilized and also contains light / UV stabilization according to current product listings. It is supplied in black and includes a release / lubricant package that supports efficient injection molding and demolding.
Compared with rigid unplasticized PA12 grades, VESTAMID L1723 BK 9.7624 is substantially more flexible. Published data for the grade shows a dry tensile modulus of approximately 525 MPa and more than 50% nominal strain at break, reflecting the tough and ductile character required for cable ties and fastening systems.
The material also provides good resistance to many chemicals, oils and fuels. This combination of flexibility, chemical resistance, moisture stability and easy processing makes it suitable for demanding industrial, electrical and automotive fastening applications.

These values show that VESTAMID L1723 BK 9.7624 remains an electrically insulating PA12 grade rather than an antistatic or conductive compound.
Why Choose VESTAMID L1723 BK 9.7624?
The principal reason to choose VESTAMID L1723 BK 9.7624 is its combination of flexibility, toughness and processability.
Cable ties and strip clips undergo significant deformation during installation. A material that is too rigid can crack or permanently deform, while a material that is too soft may not provide sufficient retention. The plasticized PA12-P formulation of this grade provides a useful balance between flexibility and mechanical strength.
The low water absorption of PA12 is also important. Many conventional polyamides absorb more moisture and can experience greater changes in stiffness and dimensions. The relatively low moisture uptake of VESTAMID L1723 BK 9.7624 helps retain predictable fit and function in environments where humidity varies.
Its low coefficient of friction is another practical benefit. Fasteners can be easier to install and can move over cables or surfaces with less resistance during assembly.
Finally, the grade’s heat, light and UV stabilization makes the black formulation useful for components that may be exposed to demanding environmental conditions.
Processing Guidelines for VESTAMID L1723 BK 9.7624

Because VESTAMID L1723 BK 9.7624 is a low-viscosity grade, Evonik’s processing literature recommends considering positively controlled shut-off nozzles, such as needle-valve nozzles, for low-viscosity grades including L1723.
Material supplied in intact moisture-proof packaging is ready for processing. If pellets have absorbed moisture after exposure to ambient air, drying should be carried out before molding.
Actual injection settings should be optimized according to part thickness, mold design, gate position, flow length and cycle-time requirements.
