What is Strip Brush? It originated from traditional labor work and was invented by the working people of the ancient Han nationality in production practice. With the continuous development of human society, summarizing life experience and innovation, strip brush seals have been given more functions and used more widely, especially in industry. How do we judge the Weather Strip Brush used in industry? Is it PA material or PP material? Let's make a simple distinction:

Weather Strip Brush

PA Flexible Nylon Strip Brush, the full name is polyamide strip brush, commonly known as nylon Strip Brush, PA for short. It is a kind of thermoplastic polymer, which is very soft, wear-resistant, and has good resilience. It can rebound instantly when folded at 90°. When it burns, it emits white smoke and a yellow flame on a blue background.

PP Door Seal Strip Brush, full name polypropylene, referred to as PP. It is also a kind of thermoplastic polymer, which is resistant to acid and alkali. In addition to being corroded by concentrated sulfuric acid and concentrated nitric acid, it is relatively stable to other chemical reagents. However, it is less flexible than PA. When burning, the flame is yellow and blue, and it will continue to burn after leaving the fire. The smell is milder than nylon.
