Items have hardness regardless of what they are, but the calculation of hardness varies from one item to another. For example,Silicone TubeIt's a special case, calculated using the Shore hardness method.
Shore Hardness: It refers to the reading obtained using a Shore hardness tester, with its unit being "degree." The description method is divided into two types, A and D, representing different hardness ranges. Generally, Shore A hardness testers are used for readings below 90 degrees, while Shore D hardness testers are used for readings of 90 degrees and above to obtain the data.
In the testSilicone TubeWhen testing the hardness, you can first feel it with your hand to determine its softness or hardness. If it feels soft, use a Shore A hardness tester; if it feels hard, use a Shore D hardness tester.
Generally speaking,Silicone TubeIf the hardness is below 30 degrees, bubbles and white spots may appear during production. Therefore, it's crucial to control the exhaust stroke and frequency properly, aiming for fewer exhausts and, if possible, a shorter exhaust stroke. Additionally, reduce the amount of curing agent. Furthermore, the molding temperature for silicone hoses can be slightly increased, but the temperature should not be too high, as this may cause edge bursting. If wind pockets (bubbles) and white spots occur, extend the curing time.
In summary,Silicone TubeSilicone tubes produced by manufacturers typically range in hardness from 30-80A, with 40A and 60A being the most common. Special hardness requirements are accommodated for specific needs.
