Features & Benefits
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. 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.
Use & Applications
- Car Radiator Front Shields
- Car Moldings
- Car License Plates
- Other Automotive Parts
