Applications:

The balanced properties of ULTRAMID B3WG6 allow it to be used in demanding applications that require both structural integrity and a high degree of dimensional accuracy.

1. Automotive Interior and Exterior Components
   • Due to its high stiffness and low warpage, B3WG6 is a preferred material for large, flat automotive parts. This includes dashboard panels, interior door trims, and exterior mirror housings.
   • The combination of glass fiber for strength and minerals for isotropic shrinkage ensures that parts maintain their complex shapes and fit perfectly during assembly, a crucial factor for aesthetic quality.
2. Durable Industrial and Power Tool Housings
   • This grade is used in industrial and electrical applications where a strong, rigid, and dimensionally stable material is needed.
   • This includes power tool casings, gear housings, and other machine components that are subject to repeated loads. The mineral content often also improves surface finish, a benefit for visible parts.
3. Appliance and White Goods Components
   • ULTRAMID B3WG6 is a suitable material for the functional parts of household appliances.
   • Its high stiffness and heat resistance are beneficial for components like pump housings, fan casings, and internal structural elements that must operate reliably over a long service life.
