The automobile sealing strip has the function of filling various intervals and gaps between the components of the body, and has the functions of shock absorption, waterproof, dustproof, sound insulation, decoration, etc., improving the comfort of the driving experience and protecting the body.

Classification according to the name of the installation part (component) of the sealing strip

Engine cover sealing strip (HOOD), which can be divided into front part, side wall and rear part; door frame sealing strip (DOORSEAL); front and rear wind window sealing strip (WINDOWSCREEN); side window sealing strip (SIDEWINDOWSEALING); sunroof sealing strip (SUNROOFSEALING); door headway sealing strip (PRIMARYDOORSEAL); window guide groove sealing strip (GLASSRUNCHANNEL); inner and outer strips (water cut) (WAISTLINE); trunk sealing strip (TRUNKSEAL); Dust strip (ANTI-DUST) and so on.

Classified by section shape

It can be divided into solid core products (round, square, flat section shapes), hollow products and metal-rubber composite products. Among them, metal-rubber composite sealing strip accounts for more than 60%. The section design is very important for the rubber sealing strip. The first is the shape and size design of the sealing lip. The sealing lips on both sides should contact the glass from both sides of the window glass with the same and appropriate force. The length and thickness of the lip should be appropriate. Too thick or too long will make the glass lift resistance too large. If too thin or too short, the glass will not be well guided and sealed, resulting in vibration, noise and rain leakage. The shape and size of the bottom of the section are designed. There are protrusions on the section of the steel groove of the window. Its function is to assemble the guide groove. Therefore, the bottom of the guide groove section should be designed with a corresponding structure, which is easy to install and can use the elasticity of the sealing strip itself. It is attached to the steel guide groove to prevent it from coming out; the last is the shape and size of the outer edge. In order to improve the appearance, the outer surface of the guide groove should be closely fitted with the body.

Classification by sealing characteristics

It can be divided into weather sealing strip (WEATHERSTRIP) and general sealing strip (SEALING). Among them, the weather sealing strip has a hollow sponge tube, which has a better temperature and humidity retention function. Common weather sealing strips include door frame sealing strips, trunk sealing strips, engine cover strips, etc. Commonly used general sealing strips include front and rear wind window sealing strips, corner window sealing strips, inner and outer strips, etc.

Classification by compound structure

It can be divided into pure rubber sealing strip - composed of a single rubber species; two composite sealing strip - composed of compact glue and foam sponge glue, often containing metal skeleton material in the axial direction inside the compact glue; three composite sealing strip - It is composed of two kinds of compact glue (one of which is light-colored) and sponge glue, and usually contains metal skeleton and reinforcing fibers inside the compact glue. Four composite sealing strips - Shanghai Shenya Sealing Co., Ltd. is the first in China to develop and produce composite sealing strips composed of 4 kinds of rubber materials, and a thin layer of protection is covered on the surface of the foam rubber (foam tube). layer glue, thereby further improving the service life of the seal.

Sort by material

It can be divided into rubber sealing strip; plastic sealing strip; thermoplastic elastomer sealing strip.

Classification by surface treatment status

Part of the surface of the sealing strip has undergone additional treatment, which can be divided into flocking sealing strips; surface coating sealing strips; and fabric-applied sealing strips.

Special function classification

Some sealing strips have electronic intelligent functions, such as anti-pinch sealing strips.
