NEMA FR4
Product Definition:
Tufflam FR4 epoxy glass cloth laminate (white/yellow/black) series is a rigid plate-like insulation material made of hot pressing of imported alkali-free glass fiber cloth impregnated with imported epoxy ester resin, and adding imported flame retardants, adhesives, etc.
Tufflam FR4 epoxy glass fiber cloth lamination sheet is a rigid insulating lamination sheet made of composed imported alkali-free glass fiber cloth ,impregnated with imported high quality epoxy resin,added the imported fire retardant and cementing compound,it is a rigid plate-like insulating material under high temperature and high pressure.
Tufflam FR4 black antistatic laminate is an insulating material specially added with anti-static material, and its surface resistivity is < 109, which achieves the function of absorbing electrostatic charge. Tufflam FR4 black anti-static laminated sheet was added specical anti-static material to meet the absorb action for electrostic charge of the insulating material surface resistivity ＜＜109
