Description: 

FR4 Epoxy Fiberglass Laminate Sheet is made of electrical-purposed, alkali-free glass cloth impregnated with epoxy resin by hot pressing. It has good mechanical and dielectrical properties. Applicable to mechanical, electrical, electronic, electrical, and other fields. It is also used in the processing of insulating parts and processed into all kinds of insulating parts and equipment insulating structural parts, which can be used in wet environment conditions and transformer oil.

FR stands for flame retardant and denotes that the safety of flammability of FR4 is in compliance with the standard UL94V-0. The FR4 epoxy laminate has a smooth surface, no air bubbles, and no pits or wrinkles, but it allows for other defects that do not affect its use, such as scratches, indentations, stains, and small spots. The edges should be cut neatly, and the end faces must be free of delamination and cracks. 

Features:

1. High mechanical performance under medium temperature.

2. Good electrical performance stability under high temperature.

3. Resist to acid and alkali. 

4. Corrosion resistance.
