We have shared full knowledge about GPO-3 insulation board in previous articles from YILONG. This article will focus on a widely concerned topic: simple identification methods to distinguish qualified finished GPO-3 insulation boards from inferior ones. Let’s take a closer look.
How to identify the defective GPO-3 Insulation Boards?
Conduct Open Flame Test with Matches
Smoke generation marks inferior products Qualified GPO-3 insulation board features excellent bonding performance and eco-friendly raw materials, so no smoke will be released during combustion. By contrast, inferior boards will produce thick smoke when ignited.
Release of toxic pungent fumes Inferior products rely on low-quality flame retardants to achieve flame resistance, which will emit irritating toxic gas while burning. As the flame retardant volatilizes gradually, the overall performance of the board declines sharply. Such inferior boards are not suitable for environments with human exposure or continuous high temperature conditions.
Delamination after burning indicates counterfeit products The mechanical tensile strength of standard GPO-3 comes from its internal uniform glass fiber mat structure. No internal delamination will occur even after high-temperature carbonization. If obvious delamination appears during combustion, the product is counterfeit and substandard.
YILONG strictly implements full inspection standards for all GPO-3 Insulation Board finished goods to guarantee stable arc resistance, flame retardancy and long service life.
