PC board is flame retardant. Sunshine board / endurance board is mainly made of PC / PET / PMMA / PP material, referred to as hollow board. PC board is produced with polycarbonate as the main raw material. Sunshine board / endurance board rapidly entered the building decoration materials in the mid-1980s.
Flame retardant: tested by * * * gb8624-97, it belongs to flame retardant grade B1. No fire drops, no poison gas.
Temperature resistance: it will not cause deformation and other quality deterioration within the temperature range of - 40 OC to + 120 OC.
Sound insulation: sound insulation effect is good. It is the * * * material of Expressway sound insulation barrier in the world
Weather resistance: after 5000 hours of artificial climate aging test, the yellowing degree is 1, and the reduction value of light transmittance is only 0.4%
Impact resistance: the impact strength of PC endurance board is 250-300 times that of ordinary glass, 20-30 times that of Yake board and twice that of tempered glass.
