The oil resistance of sealing strips in the construction industry is second only to polysulfide rubber, acrylic rubber, and fluororubber. In addition, nitrile rubber also has good wear resistance, aging resistance, and air tightness, 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 of adjusting molecular weight and lowering the polymerization temperature to 5 ℃ are often used to reduce side reactions and improve its processing performance.

Nitrile rubber can also be improved in performance by blending with various rubbers such as chloroprene rubber, isoprene rubber, butadiene rubber, styrene butadiene rubber, and synthetic resins such as polyvinyl chloride and phenolic resin (see polymer blends). 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.

There are still many manufacturers in the door and window industry who do not pay attention to the technical connection and integrity of the door and window system. The door and window profiles and accessories used are pieced together, making the materials and accessories that are not very compatible with each other come together, resulting in many problems and defects after the doors and windows are made, or problems caused by uncontrolled processing technology.

After Z, sealing strips are used to compensate for the defects of windows, in order to improve the overall performance of doors and windows and meet the standards of energy-saving doors and windows. To solve such problems, the high and low product design and technical production capabilities of sealing strip manufacturers are crucial.

Using various materials of different colors that are coordinated with the exterior surface composite and automotive interior, such as colored EPDM and colored thermoplastic elastomers; Replace the original flocking material with surface sprayed wear-resistant and lubricating materials; Apply various smooth, matte, or colored four composite materials by surface spraying.
