The vulcanization time of insole silicone has a significant impact on product performance. If the vulcanization time is too long or too short, the performance will be reduced. The specific manifestations are as follows:
The impact of too short vulcanization time
Incomplete vulcanization: Silicone products may have problems such as insufficient elasticity, insufficient strength, and poor aging resistance.
Risk of use: Insole with incomplete vulcanization is prone to performance degradation and cracking during use, which seriously affects the service life.
The impact of too long vulcanization time
Vulcanization reversion: Silicone may be over-vulcanized, resulting in a decrease in physical properties, such as reduced elasticity, excessive hardness, and poor wear resistance.
Appearance defects: The product may have bubbling or bursting edges, affecting the appearance quality.
Reduced production efficiency: Too long vulcanization time will increase energy consumption and production costs, and reduce production efficiency.
Balance between vulcanization time and product performance
Performance optimization: Reasonable vulcanization time can ensure that silicone insoles achieve ideal elasticity, strength and aging resistance.
Cost control: Accurate control of vulcanization time can avoid energy waste and low production efficiency, and reduce production costs.
Method for determining vulcanization time
Experimental verification: To determine the optimal vulcanization time through experiments, it is necessary to comprehensively consider factors such as silicone formula, vulcanizer type, and mold design.
Process adjustment: Adjust the vulcanization time according to parameters such as product thickness and vulcanization temperature to ensure that the product is fully vulcanized.
