The oil resistance of sealing strips is second only to polysulfide rubber, acrylate rubber, and fluororubber. In addition, nitrile rubber also has good wear resistance, aging resistance, and airtightness, but its ozone resistance, electrical insulation, and cold resistance are relatively poor, while its conductivity is relatively good. Therefore, it is widely used in the rubber industry. In industry, more effective methods are often used to adjust the molecular weight and the polymerization temperature is reduced to 5℃ to reduce side reactions and improve its processing performance.

Nitrile rubber can also be blended with various rubbers such as chloroprene rubber, isoprene rubber, cis-butadiene rubber, styrene-butadiene rubber, and synthetic resins such as polyvinyl chloride and phenolic resin (see polymer blends) to improve its properties. It can be used for a long time in air at 120℃ or in oil at 150℃. In addition, it also has good water resistance, airtightness, and excellent bonding performance.

Many manufacturers still do not consider the technical connection and integrity of the window system. The window profiles and accessories used are pieced together, resulting in a combination of materials and accessories that are not well-matched, leading to many problems and defects after the windows are made, or problems caused by poor process control.

Finally, sealing strips are used to compensate for the defects of the windows to improve the overall performance of the windows and meet the standards of energy-efficient windows. To solve such problems, the product design capabilities and technical production capabilities of sealing strip manufacturers are crucial.

Using surface composite materials with various colors that coordinate with the car interior, such as colored EPDM and colored thermoplastic elastomers; using surface spraying of wear-resistant and lubricating materials instead of the original flocking materials; applying surface spraying of various smooth, matte, or colored four-composite materials.
