Electroplating Compatibility

Tailored for electroplating, POLYLAC PA-726M ensures strong metal layer adhesion for lasting quality and appearance. This is crucial for applications like car license plates. It resolves the pain point of coatings peeling off, ensuring a reliable, high-quality finish that enhances product longevity.

Durable Impact Strength

With an Izod impact strength of 20 KJ/m² at 23°C, POLYLAC PA-726M offers excellent resistance to impacts, making it ideal for robust applications like car radiator front shields. This feature addresses the challenge of parts breaking under minor collisions or vibrations, such as debris hitting the front of a vehicle, ensuring safety and durability.

High Temperature Tolerance

Boasting a Vicat softening temperature of 103°C and a heat distortion temperature (HDT) of 81°C, PA-726M material performs reliably in various thermal conditions. This is essential for car moldings near engines, where heat exposure is common, preventing deformation and maintaining structural integrity, thus solving the issue of parts failing in high-temperature environments.
