1、成分不同

1. Different components

泡沫復(fù)合板的主要原材料是聚氨酯泡沫，巖棉復(fù)合板則是把巖棉和鋼板復(fù)合成一個(gè)整體而成。

The main raw material of foam composite board is polyurethane foam, and rock wool composite board is composed of rock wool and steel plate as a whole.

2、阻燃性不同

2. Different flame retardancy

巖棉復(fù)合板可以很好地阻止物體的燃燒，小火能夠自動熄滅，泡沫復(fù)合板中的聚氨酯泡沫是一種可燃物質(zhì)，沒有通過阻燃處理。

The rock wool composite board can well prevent the burning of objects, and the small fire can be automatically extinguished. The polyurethane foam in the foam composite board is a combustible material and has not been treated with flame retardant.
