It can be lit with a match.

1. It is inferior products that have smoke and dust. GPO-3 insulation board products have very good adhesion, the material itself is environmentally friendly and does not produce smoke and dust.

2. Poisonous gas is produced. Inferior products generally use flame retardants to achieve the flame retardant effect, so there is a pungent poisonous gas when burned. With the volatilization of the flame retardant, the performance of the product is also reduced, and it cannot be used in an environment where people are in contact with it or in a hot environment.

3. Burning stratification. Due to the irregular structure of the glass fiber mat, the mechanical tension of GPO-3 comes from the inside, and the internal stratification will not occur during high-temperature carbonization. If the burning is stratified, it is a counterfeit product.
