How to distinguish true GPO-3
1. Genuine GPO-3 panels have passed the U.S. Safety Laboratory certification (UL certification), so they have independent UL identification file numbers. When purchasing this product, you should ask the manufacturer to provide the UL identification file number to verify the authenticity.
2. The leakage resistance index of the real GPO-3 board can reach 600V.
3. The density of the real GPO-3 board is between 1.81 and 1.83 according to international standards. It does not contain fillers, which determines the reliable stability of the board.
Simple method to distinguish finished GPO-3 products from inferior ones
It can be lit with matches.
1. Products that produce smoke and dust are inferior products. GPO-3 products have very good adhesion, the material itself is environmentally friendly and will not produce smoke and dust.
2. Toxic gas is produced. Inferior products generally use flame retardants to achieve flame retardant effect, so there is pungent poisonous gas when burning. As the flame retardant evaporates, the product performance also decreases. It cannot be used in an environment where people come into contact with it or in a hot environment.
3. Combustion stratification. Due to the irregular structure of glass fiber felt, the mechanical tension of GPO-3 comes from the inside, and internal stratification will not occur during high-temperature carbonization. If stratification occurs during combustion, it is a counterfeit product.
