Due to the gradual expansion of the insulation market, there is a phenomenon of confusion among major products. With the high flame retardant and heat-resistant GPO-3, it is difficult to distinguish between true and false, and the most difficult to distinguish. Today, the GPO-3 production factory, Haichen Composite Materials, teaches you three ways to distinguish between true and false.
How to distinguish between real GPO-3?
1. The real GPO-3 board is certified by the UK Safety Laboratory (UL), so there is a separate UL identification document number. When purchasing this product, the manufacturer should be required to present the UL identification document number to distinguish between authenticity.
2. The true GPO-3 board can achieve a resistance index value of 600V.
3. The true GPO-3 board has a relative density between 1.81 and 1.83 according to the national standard, and there is no filling material in it, which determines the reliable reliability of the board.

1. The products with smoke and dust are of inferior quality. The GPO-3 product has excellent adhesion and the material itself is environmentally friendly, without generating smoke and dust.
2. Non toxic gas generation. Poor quality products generally use flame retardants to achieve flame retardancy, so there is a pungent toxic gas during combustion. With the volatilization of flame retardants, the performance of the product also decreases, and it can no longer be used in environments with human contact or in hot environments.
3. Combustion layering: Due to the irregular structure of glass fiber felt, the mechanical tension of GPO-3 comes from inside, and internal layering does not occur during high-temperature carbonization. If there is layering during combustion, it is a counterfeit product.
