In the door sealer industry, because wool has good sealing properties, natural wool can be used to produce door bottom sealing brushes through certain processing procedures. Can you tell the authenticity of the wool door sealer?

The wool door sealer has a very thin silk diameter, so it feels very soft and elastic to the touch. Usually we can try the "simple and rough" method to test whether the wool door sealer is genuine or fake, that is, the burning method. When burning the wool door sealer with a lighter, we have to observe its condition and smell it. When it burns again, it will smoke and foam, accompanied by the smell of burning hair. After burning, there will be more ash, which will form a black brittle and fast shape. Those are some of the characteristics of organic fiber wool door sealers. Generally, door sealers of this material are mostly used under revolving doors. We call them revolving door sealing brushes, which can seal dust and clean, and can also effectively block small Worm enters inside
