Rubber Seal strip

Under the conditions of an ozone concentration of 50pphm and a stretching of 30%, the rubber sealing strip can last for more than 150 hours without cracking, and has weather resistance (operating temperature range -40-150) and chemical resistance. After adding flame retardants, it has good flame retardancy and flame retardancy. The product is processed by microwave continuous vulcanization once, with a smooth and beautiful surface, more stable performance, and not easily changed.

Classification of standard vulcanization methods for rubber sealing strips

Sulfurization can be divided into two types: discontinuous vulcanization and continuous vulcanization. Discontinuous vulcanization: Cut the prepared rubber strip to a certain length, place each cut into a vulcanization tank for vulcanization, and then place the formed rubber strip into the corresponding mold for vulcanization to produce the finished product; In discontinuous vulcanization, the standard for rubber sealing strips is that the finished product should be soft, not too hard, smooth on a flat surface, and should not have any abnormal noise. Continuous vulcanization: The basic requirements for continuous vulcanization are similar to those for discontinuous vulcanization. The difference is that the production process is not segmented cutting, but continuous, with a fixed length generally above 100 meters; In continuous vulcanization, the standard for rubber sealing strips should be flexible, not too hard, flat and smooth on a flat surface, and should not have cracks.

Standard material classification for rubber sealing strips

The basic materials for rubber sealing strips are divided into three types: sealing rubber, sponge rubber, and hard rubber. Even solid rubber, sponge rubber, and hard rubber can have inferior rubber sealing strips during the manufacturing process. Therefore, in material classification, not only should the quality of the material be used as the standard for rubber sealing strips, but also the review should be based on the rubber sealing strips. The audit criteria are: soft, not too hard, smooth and even on a flat surface, without any squeaking or rattling areas.
