357 Modified bismaleimide glass cloth laminate Details

The 357 modified bismaleimide glass cloth laminate is made by an electrician using an alkali-free glass cloth dipped modified bismaleimide resin, which is baked and hot pressed.

Appearance: Sepia, smooth surface, no bubbles, impurities and other obvious defects allow slight scratches, edges should be cut neatly and the end faces are free of delamination and cracks.

 

Performance:

1. High mechanical and dielectric properties
2. Good moisture resistance and processability
3. Heat resistance grade is H grade performance:
