Strip brushes must be produced with new pure filaments. In order to save costs, some Strip Brushes Suppliers use recycled filaments for production. The performance of the finished product is extremely unstable, and it is prone to aging, deformation and even wire breakage. If the unqualified Metal Channel Strip Brushes are put into use, it is easy to cause serious accidents.

It is difficult for us to distinguish the recycled wool from the naked eye, and we can only rely on microscopes and other equipment to help us observe. Generally, the brush filaments of poor quality have felt the presence of burrs on the touch and are rough. This type of Metal Back Strip Brush often results in substandard tensile force due to the poor quality of the brush wire. After a period of use, the entire Strip Brush Seal will leak light.

Not only the brush filaments, but also the fastening lines and bases of some inferior Industrial Strip Brushes will also be made of inferior recycled materials. The unscrupulous Strip Brushes Factory will directly choose low-cost, doped fastening iron wires or stainless steel wires, or bases with poor electrolytic, galvanized, or stainless steel processes. Because the oxide layer on the surface has been oxidized, it has lost its protective effect. After a period of use, it will rust and even become unusable.

Since most of the materials used for secondary recycling contain low-molecular-weight substances, catalysts and heavy metals, long-term use of Strip Brush Seal made of second-hand materials may affect human immunity, causing dizziness, nausea, loss of appetite, and memory. Symptoms such as decline can cause irreversible harm to people.
