door and window rubber seal strip
Jan 12, 2019

   Door and window seals are mainly used in plastic steel doors and windows, aluminum alloy doors and windows, wooden doors and windows and other architectural decoration doors and windows of a kind of seals. The plastic steel door and window seals on the market are generally extruded from PVC, modified PVC, EPDM, elastomer seals (including TPV, TPE, TPR, SEBS), silica gel and other materials.

  The sealing strip of doors and windows can be divided into three categories: glass sealing strip (rubber strip), door cover sealing strip and wool strip. Glass sealing strip is used for sealing between glass and fan and frame, door cover sealing strip is mainly used for sealing between door plate and door frame, wool strip is mainly used for sealing between frame and fan. Sealing strip is an indispensable accessory in the production and installation of plastic steel doors and windows, broken bridge aluminum doors and windows, wooden doors.

  Sealing tape plays an important role in waterproofing, sealing and energy saving of plastic steel doors and windows, broken bridge aluminum doors and windows, wood doors and windows, sound insulation, dust proof, freezing proof and warmth preservation. It must have a strong tensile strength, good elasticity, but also a better temperature resistance and aging resistance. In order to ensure the tightness of the strip and profile, the section size of the strip must be matched with the profile of plastic steel doors and windows. Sealant strip is generally used for opening doors and windows flat, hanging windows, folding doors and windows. Its main functions are dust-proof, insect-proof, waterproof, sound insulation, sealing, etc.

  The installation part of the wool strip is usually on the push-pull window (door) fan, around the frame fan or on the sealed bridge (windshield block), which enhances the sealing between the frame and the fan. Top specification is an important factor affecting the water tightness of push-pull doors and windows, as well as the switching force of doors and windows. It is not only difficult to assemble, but also increase the moving resistance of doors and windows, especially the initial resistance when opening and the final resistance when closing. The size is too small, or the height of vertical wool is not enough, so it is easy to get out of the groove, which greatly reduces the sealing performance of doors and windows.

  There are two kinds of wool tops, silicified and non-silicified. The quality of the treated wool tops is better in use. The surface of the qualified wool tops is straight, the bottom and vertical wool are smooth, without bending, and there are no pitting on the bottom, which conforms to the requirements of 0.2mm.
