Silicone is a common synthetic material, and its hardness can be adjusted according to needs. The main differences between silicone with different hardness are as follows:

Elasticity and softness: The hardness of silicone is directly related to its elasticity and softness. Softer silicone is softer and has higher elasticity, while harder silicone is relatively harder and has lower elasticity.

Carrying capacity: The different hardness of silicone also affects its carrying capacity. Harder silicone can withstand greater pressure and weight, while softer silicone is suitable for applications with lower pressure requirements.

Usage scenario: Silicone with different hardness is suitable for different usage scenarios. For example, softer silicone is suitable for making soft sealing or shock pads, while harder silicone may be used for making structural or hard seals.

Processing and cost: The hardness of silicone also affects its processing difficulty and cost. In general, harder silicone may be easier to process, while softer silicone may require more complex manufacturing processes, resulting in higher costs.

Durability: harder silica gel usually has higher durability and anti-aging performance, while softer silica gel may be more vulnerable to damage or wear.
Overall, the hardness of silicone should be determined based on specific application requirements. Silicone with different hardness has different advantages and limitations in different fields, so it is necessary to comprehensively consider various factors when selecting.
