 1. COMPOSITION AND PRESENTATION
NEMA-L is a stratified insulator made from cotton cloth and phenolic resin.
At delivery time the presentation of the sheets is as follows:
- Maximum sizes: 1020 X 2040 mm.
- Thickness: From 0.50 mm
- Colour: Dark Brown
- Surfaces: Shining
- On demand we can deliver strips or finished components.
2. PROPERTIES AND APPLICATIONS
- Excellent mechanical properties
- High resistance to blows and vibrations.
- High resistance to friction, for general industrial applications
Mechanized pieces of big size for mechanical applications such as ball bearing, silent gearing for modulessuperior to 2.5, ball bearing caps, pulleys. It also can be used as insulating construction parts in electrical equipment.
