Silicone rubber and plastic (PP) are difficult to stick. If the requirements are not high, RTV room temperature cured silicone rubber can be used. If it is uncured liquid silicone rubber and PP, first brush primer on PP, and then over molding with PP after primer drying. If the primer is selected correctly, it can achieve real adhesion and cannot be separated. Different types of PP may have different bonding effects.

The surface of polytetrafluoroethylene is extremely smooth, and ordinary glue is difficult to bond. It must be treated with polytetrafluoroethylene surface treatment agent before bonding (polytetrafluoroethylene surface treatment agent can be provided by ala Chenguang fluoroplastic factory in Kunming Economic Development Zone). Our treatment agent has been widely used in projects such as polytetrafluoroethylene tight lining, and the treatment effect is good. The bonding between polytetrafluoroethylene and steel depends on what you do. If there is no load-bearing and stress, you can directly use hot melt or polytetrafluoroethylene welding gun for bonding. If there is, you have to consider the structure and stress surface or point.

Polytetrafluoroethylene, commonly referred to as "non stick coating" or "easy to clean wok material" ； It is a synthetic polymer material that uses fluorine to replace all hydrogen atoms in polyethylene. This material has the characteristics of acid resistance, alkali resistance and resistance to various organic solvents, and is almost insoluble in all solvents. At the same time, polytetrafluoroethylene has the characteristics of high temperature resistance, and its friction coefficient is very low, so it can be used for lubrication. Besides, it has also become an ideal coating for easy cleaning woks and the inner layer of water pipes. Commonly known as "plastic king", it has the characteristics of acid resistance, alkali resistance and resistance to various organic solvents, and is almost insoluble in all solvents. At the same time, polytetrafluoroethylene has the characteristics of high temperature resistance and extremely low friction coefficient, which is often used for non stick pot coating. In addition, this is also the common raw material belt at the pipe jo
