Silicone Pile Weatherstrip
Silicone-treated pile for better water resistance and aging resistance.
Hardened pile brush seal without silicone treatment.
XINHAI manufactures the Brush Seal (Non-Silicone) as a pile weatherstrip for B2B engineering applications. The seal uses hardened PP polypropylene yarn. It is a non-silicone product, so no silicone treatment is specified for the pile. Base width is available from 4 mm to 25 mm. Pile height is available from 5 mm to 20 mm. Choose adhesive or non-adhesive backing. Choose fin or plain profile. These options support anti-wind, noise, and dust control in compatible assemblies. The brush seal can be supplied in various dimensions, colors, and densities. Silicone and non-silicone versions are both offered; this page covers the non-silicone version. As a pile weatherstrip manufacturer, XINHAI produces this component for B2B buyers. Engineers should confirm base width, pile height, mounting method, profile, color, density, and gap conditions against the application. No performance beyond the stated material, dimensions, and configuration is implied. This description lists verified product facts only.
