In order to ensure consumers' confidence in the purchased thermal insulation film products, 3M China Co., Ltd. introduced the electronic quality assurance system for automotive thermal insulation films. The genuine thermal insulation and explosion-proof film of 3M Company will not produce odor after tearing off the isolation layer, while most fake 3M thermal insulation and explosion-proof films will produce irritating odor after tearing off the isolation layer. The thermal insulation and explosion-proof membrane of 3M company will not stick to hands, and the counterfeit products are more sticky in hand than the genuine thermal insulation and explosion-proof membrane of 3M. Pay attention to the outer packaging: the entry label of Waigaoqiao Free Trade Zone is attached to the carton, and the standard 3M logo is printed on the outer packaging. The heat insulation film is made of red plastic, and a white label is stuck in the tube core, indicating the product batch number and anti-counterfeiting mark. The heat insulation film has a good wear-resistant layer, which is generally scraped with nails without leaving traces. The rubber surface of the heat insulation film will not fade under the friction of sharp tools. The rubber surface of the heat insulation film is sprayed with carburetor cleaner, which is not easy to fade. The core of the heat insulation film has anti-counterfeiting marks. The above is a more emotional understanding. The final identification method is to determine the authenticity of 3M thermal insulation and explosion-proof membrane through spectrum analyzer!
