Improving the heat resistance of liquid silicone can be achieved through the following methods:
1. Adding heat resistant agents
Choosing appropriate heat resistant agents: Liquid silicone can enhance its heat resistance by adding specific heat resistant agents. For example, Crystal Liquid Transparent Heat Resistant WT925 is an effective choice, which can improve the high temperature resistance of silicone to 300 degrees. This type of heat resistant agent has good fluidity under liquid conditions, can quickly disperse and give silicone excellent heat resistance and anti-aging properties.
Other heat-resistant materials: You can also consider adding high temperature resistant materials such as silicone rubber, polyketimide, polyimide, etc., which can maintain their stability and long-term durability at high temperatures.
2. Adjusting the formula ratio
Optimizing the formula: In the production process of liquid silicone, it is very important to enhance its heat resistance by adjusting the formula ratio. For example, an appropriate amount of fillers such as glass fiber can effectively improve the heat resistance of silicone, making it less likely to deform at high temperatures.
Adding reinforcing agents: In addition to glass fiber, high temperature resistant reinforcing agents such as metal oxides and carbon fibers can also be added to improve the heat resistance and strength of silicone.
3. Improve the manufacturing process
Optimize the vulcanization method: The vulcanization method and time of silicone will also affect its heat resistance. By optimizing the vulcanization process, such as adjusting the vulcanization temperature and time, the heat resistance of silicone can be further improved.
Strictly control the production process: In the manufacturing process of silicone, the production process should be strictly controlled to ensure that each production link meets the quality standards to reduce defects and impurities in the production process, thereby improving the overall performance of silicone.
