Mr. Jiang called to ask our company how to initially judge whether the door letterbox brush is PA flame retardant. Because he suspects that the quality of the brushes provided by his existing supplier is inconsistent with the original goods.

As a professional manufacturer of door letterbox brushes, this is certainly not difficult for us. So, our Miss Chen immediately used a small video to film the difference between PA and PP. In the video, the combustion test and appearance observation are used to distinguish PP and PA.

After watching the video, Mr. Jiang said that in fact, before he found us this time, he had verified through a third-party inspection that his existing supplier had stolen the door letterbox brush materials. He wanted to find a new supplier through consultation to determine our professionalism. As a result, he was convinced before he had inspected the factory, so he decided to complete the process as soon as possible to supply large quantities.
