Advanced polymer sound-damping solutions
In the automotive industry, sound damping is a key focus for manufacturers of polymer components. Materials with sound-damping properties help improve acoustic comfort by reducing noise and vibration.
Beyond automotive applications, these solutions are increasingly important in high-rise construction and modern building design. Silent sewage and wastewater piping systems are another growing area where effective noise reduction is essential.
For these applications, we offer MagniF – a high-performance product made from natural iron oxide magnetite. Sourced from our own mines in Northern Sweden, MagniF provides consistent quality, reliability, and excellent sound-damping performance for demanding industrial use.
Key benefits:
-
Increases density for high-performance polymer compounds
-
Improves sound and vibration damping performance
-
Reduces noise transmission in demanding applications
-
Enables high filler loading levels (60–80 wt%)
-
Supports excellent surface finish in finished parts
-
Easy to process using standard methods (extrusion and injection moulding)
-
Ensures consistent and reliable material quality
High filling levels of 60–80 wt% are typical in sound-damping applications to ensure effective noise transmission reduction or elimination. MagniF-filled compounds can be extruded into high-density parts with an excellent surface finish. These polymer components are primarily used in the automotive industry to reduce engine noise transmission into the cabin.
Producers have observed an excellent balance between sound damping, surface quality, and mechanical performance when using MagniF.
Please get in touch with one of our application experts. We look forward to helping you find the best solution for your sound-damping polymer product.
