What are the effects of different softness and hardness on functionality?

Small components are used in every industry, so there are also many things that happen around us due to small losses. Sealing and protective equipment in various industries cannot do without the assistance of silicone accessory materials. The role and influence of silicone components can play a great role in the combination of many products, and the adjustment of softness and hardness can completely affect any functional problems. Therefore, if the hardness of silicone accessories is not selected properly, it can also cause quality problems. What are the effects of different hardness and softness on functionality!

Spare parts are mainly used for assembly, sealing, shock absorption, protection, and intermittent use, while the softness and hardness values of silicone have drawbacks in different functional aspects.

In terms of sealing function, if the hardness value of silicone sealing accessories is high and the folding and bonding strength is low, it is likely to cause idle leakage, and the service life will be affected after long-term stress aging, resulting in damage and cracking. A low hardness value can provide cushioning for functionality, and reducing hardness as much as possible in waterproof function can achieve more effective waterproof effect. However, the material and thickness of the product must be appropriate to achieve good extension and rebound strength.

In terms of buffering and shock absorption, silicone products need to achieve a medium to high hardness value as much as possible. Due to the influence of force, a low hardness value of the product may lead to insufficient shock absorption effect and failure to achieve functionality. Secondly, after the low hardness silicone accessories are assembled, they are likely to achieve the effect of active buffering and shock absorption, leading to looseness and detachment. Increasing the hardness value not only improves the firmness, but also achieves buffering effect due to the high hardness value.

Assembly, many silicone accessory manufacturers understand that sealing accessories are assembled from different materials, and the completeness of assembly is also affected by hardness, leading to functional problems of the product. High hardness materials are not easy to assemble, and the higher the hardness, the smaller the tensile rebound. Therefore, when assembling high hardness accessories, try to minimize their tensile strength. Low hardness assembly is better, but attention should also be paid to the problem of excessive tensile extension.
