Brief introduction of two kinds of high temperature resistant silicone tube manufacturing process

High temperature resistant hot air pipe is made of glass fiber cloth flame retardant polymer material, silicone rubber, high elastic steel wire, high temperature wire, and vulcanized and compounded at 300 ℃. Compared with the traditional air duct, the high temperature resistant silicone hose has the characteristics of high temperature resistance and flame resistance. It has been widely used in hot and cold air circulation conveying systems, such as pellet dryers for plastic industry, injection molding machines, hot air circulation dryers, printing machinery, heat fans and compressors, and exhaust emissions, automobile engine heating, train hot air circulation systems, aviation equipment And military equipment. There are two types of high temperature resistant hot air pipes: high temperature vulcanized silica gel hot air pipes and room temperature vulcanized silica gel hot air pipes. What are the differences between the two high temperature resistant hot air pipe manufacturing processes? The following introduction characteristics and manufacturing processes of the two types high temperature resistant hot air pipes. I believe the below content can help everyone buy more suitable hot air pipes.

First, high temperature vulcanized silicone hot air pipe

This is a high temperature resistant hot air pipe produced by a high temperature vulcanization process. The material used for this pipe is more environmentally friendly. The produced hot air pipe has a very smooth and beautiful appearance, and has strong aging resistance. It has a longer service life than ordinary hot air pipes. Of course, this cost will also be higher than the ordinary ducts, and the output is relatively low, so the selling price is almost double that of ordinary ducts.

Second, room temperature vulcanized silicone hot air pipe

Room temperature vulcanized silicone hot air pipes are a few years old process. They are all coated by room temperature vulcanized silicone rubber. They are produced by hand. In addition, they can be vulcanized at room temperature. Therefore, the price is lower than high temperature vulcanized hot air pipes. However, room temperature vulcanized silicone rubber has more impurities, and the coating will have particle burrs. The appearance of higher temperature vulcanized silicone tube is worse, and it will be flat when bent, not environmentally friendly, and has poor aging resistance. The products produced will age in the storage warehouse for half a year without being used, so in recent years, the hot air pipes produced by this process have been gradually phased out.
