► Performance characteristics and applications of fluororubber strips
 

Fluorine rubber strips are a lightweight material that is resistant to high temperatures, corrosion, corrosion agents, oxidants, and radiation, so they are widely used in the fields of chemical industry, pharmaceuticals, and food. Its main advantages include: long service life, good dimensional stability, strong high temperature resistance, good chemical stability, and good insulation performance. At the same time, due to its excellent sealing performance, fluororubber strips are also widely used in sealing joints in different fields such as pipelines and containers.

 

 

► Fluorine rubber strip extrusion vulcanization process steps

1. Raw material preparation. First, it is necessary to prepare the raw materials of fluororubber strips, including polytetrafluoroethylene (PTFE), various pigments, fillers, additives, etc., to ensure that the purity of the raw materials meets certain standards.

2. Extruder extrusion. The raw materials are fed into the extruder for extrusion, and different extrusion molds are selected according to the needs of product size and shape, and the fluororubber strips are extruded through the molding port in the mold.

3. Vulcanization processing. The extruded fluororubber strips are vulcanized, and the fluororubber strips are formed and the required performance is achieved through heating, cooling and other process steps.

 

 

► Issues that need to be paid attention to in the extrusion and vulcanization process of fluororubber strips

1. Purity of raw materials. Before extruding fluororubber strips, the raw materials need to be fully screened and purified to ensure the quality of the product.

2. Selection of extruder. The quality of the extruder is very important for the molding effect and stability of the product, so it is necessary to choose an extruder of high quality.

3. Accurate control of the vulcanization process. The temperature and time need to be accurately controlled during the vulcanization process to ensure the vulcanization degree of the finished product.
