What Is Epoxy Sheet of EU Fire Ratings?

What is the general fire rating of epoxy board?

First of all, epoxy plate is divided into a variety of grades: FR4 epoxy plate, FR5 epoxy plate. epgc201-208 grade epoxy plate, G10/g11 epoxy plate 3240 epoxy plate, epoxy plate is divided into a variety of colors: aqua green mostly yellow 3240 epoxy plate, black epoxy plate

Epoxy plate continuous working temperature of 120 ℃, 170 ℃ is the limit temperature Short-term theoretical temperature epoxy plate can reach 150 degrees, water green color can reach 170 degrees, HONY Plastic produced by the epoxy plate can not only meet the domestic epoxy board fire standards, but also can meet the EU fire standards.

The EU fire rating is this one. UL is the world's best fire rating standard. Flame retardant grade from HB, V-2, V-1 to V-0 step by step increase.

HB: The lowest flame retardant rating in the UL94 standard. Requires a burning rate of less than 40 millimeters per minute for samples 3 to 13 millimeters thick; less than 70 millimeters per minute for samples less than 3 millimeters thick; or extinguished before the 100 millimeter mark. V-2: After two 10-second burn tests on the sample, the flame is extinguished within 60 seconds. There may be a drop of burning material. V-1: Flame extinguished within 60 seconds after two 10-second burn tests on the sample. No combustibles can fall out. V-0: After two 10-second burn tests on the sample, the flame goes out within 30 seconds. No incendiary material can fall.
