Rubber sealing strip, foam strip common knowledge question and answer
2024-09-11
Rubber sealing strips are usually made of rubber materials with excellent aging resistance, such as chloroprene rubber, silicone rubber, natural rubber-chloroprene styrene rubber and rubber plastic mixture, according to the use of the site can be divided into four categories: marine sealing strips, automobile sealing strips, mechanical sealing strips and door and window sealing strips, including container sealing strips and cabinet sealing strips.
Rubber sealing strips are usually used in the range of -50~70 ℃. The process is divided into dense rubber belts, sponge rubber belts, two composite rubber belts and three composite sealing belts. Different cross-sectional structures can be designed according to their use location and conditions, taking into account aging resistance, oil resistance, heat resistance, fire resistance, daylight resistance, ozone resistance, acid and alkali resistance, chemical resistance, flame retardant performance requirements. The production and vulcanization method of the rubber sealing strip usually adopts the extrusion continuous vulcanization method of the rubber extruder, the vulcanization method of the extrusion molding vulcanization tank or the molding vulcanization method, and the surface of the rubber sealing strip thus prepared is very flat. If you look at its surface, you will find that its surface has a very uniform foam density layer, and also has good rebound performance, among which, it has good sealing performance, high temperature and weather resistance, aging resistance, impact resistance and Water resistance. If the back tape is self-adhesive, some rubber seals can also bond smooth surface materials.
