The weather in the south was relatively humid some time ago. AOQUN BRUSH received a consultation call asking if the nylon strip brush seal in use has become soft. Is it the quality that is not good enough? As a strip brushes Companies with more than ten years of production experience, AOQUN BRUSH tells you: Not necessarily.

Nylon Strip Brush Seal

The flexible nylon strip brush becomes soft during use, mostly due to the absorption of moisture in the air. The water absorption of different nylon materials is different, because the main component of nylon is polyamide, and its amide group is polar, which will make nylon have water absorption and dehydration. In fact, it is not a bad thing that Nylon Brush Strips absorb water vapor in the air. Working in a dry and low temperature environment for a long time will cause dehydration of the Nylon Brush Strips seal, which will become brittle and easy to break.

For quick delivery, some brush manufacturers will produce Nylon Brush Strip in advance and stack them in the warehouse at will. If the brushes are made without moisture-proof and waterproof measures, the brush filaments will become soft. When purchasing nylon bristle strip, you can feel the dry humidity of the brush by hand to avoid making mistake.
