Types of Car Sealing Strips

Car sealing strips have the role of filling various intervals and gaps between the body components, with shock absorption, waterproof, dustproof, sound insulation, decoration, and other functions to improve the comfort of the driving experience and protection of the car body.

Classification by section shape

Can be divided into solid-core products (round, square, flat section shape), hollow products and metal-rubber composite products, and other types. Among them, metal-rubber composite seals account for more than 60%. For the rubber sealing, strip section design is crucial. First of all, the seal lip shape, size design, both sides of the seal lip should be the same, the size of the appropriate force from both sides of the window glass contact glass. The length and thickness of the lips should be appropriate, too thick, too long will make the glass lifting resistance is large, too thin, too short and will lead to the glass can not be well guided and sealed, resulting in vibration, noise, rain leakage phenomenon; second is the shape and size of the bottom of the section design, the window steel groove section has a raised, its role is to assemble the guide groove, therefore, the bottom of the guide groove section should be designed to the corresponding structure, both easy to install, but also to use Finally, the shape and size of the outer lap 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 strips (WEATHERSTRIP) and general sealing strips (SEALING). Among them, the weather sealing strip with a hollow sponge bubble tube has a better temperature and humidity retention function. Commonly used weather sealing strips include door frame sealing strips, luggage compartment sealing strips, engine compartment cover strips, etc. Commonly used general sealing strips include front and rear windshield sealing strips and corner window sealing strips, inner and outer side strips, etc.

Classification by the compound structure of rubber

Can be divided into pure rubber seal — by a single rubber composition; two composite seal — by the dense rubber and foam sponge rubber composition, often in the dense rubber inside the axial direction contains metal skeleton material; three composite seal — -composed of two kinds of dense rubber (one of them is light-colored) and sponge rubber, usually contains metal skeleton and reinforcing fiber inside the dense rubber. Four composite seals — Shanghai Shenya Seals Co., Ltd. is the first in China to develop and produce a composite seal composed of four kinds of adhesive materials, and a thin protective layer of adhesive is wrapped around the surface of the sheep adhesive (bubble tube), thus further improving the service life of the seal.

Classification by material species

Can be divided into rubber seals; plastic seals; thermoplastic elastomer seals.

Classification by surface treatment state

Part of the sealing surface after additional treatment can be divided into flocking class seals; surface coating seals; fabric decorated seals

Special function classification

Some seals have electronic intelligent functions, such as anti-pinching seals, etc.
