Koz İplik Finned Weatherstrip, developed for sliding systems, provides superior sealing performance during dynamic structural movements. Its patented fin design distributes pressure 40% more evenly than traditional pile weatherstrips, yielding excellent insulation in glass balcony systems and sliding windows.

Thermoplastic polyurethane (TPU) fins of various heights are integrated onto a 0.70 mm PP base. These fins have a low friction coefficient (μ < 0.15), which minimizes energy loss during movement. This product withstands heavy-load conditions with a compressive strength of 1600 N/mm², while its PP fibers (at 5000 filaments/cm² density) neutralize dust and water infiltration. Favored in the automotive industry for vehicle glass seals and in industrial door systems, this solution has successfully passed durability tests exceeding 100,000 motion cycles.
