Brush seal UP, width 6.7 mm


Made of woven multifilament polypropylene yarn, specially treated to give every fibre a large sealing area. The silicone treatment is applied during manufacture of the fibre, making the brush seal extra abrasion-resistant and water-repellent as well as reducing friction. 

The backing fabric is coated with polypropylene to give good strength and stiffness. It makes the strip flexible and easy to install. 


Stabilises sliding motions and gives low friction. Windows and doors move silently and easily. It has very good sealing properties against air, water and noise. Polypropylene has very good abrasion resistance characteristics, is resistant to biological attack and stable to UV radiation. 

The density for the 6.7 mm weather strip are three rows of bristles. Available with denser or sparser bristles.
