Items have hardness regardless of their type, 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: Refers to the reading obtained using a Shore hardness tester, measured in "degrees." 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 initially feel it with your hands to determine its softness or hardness. If it's soft, use the Shore A hardness tester; if it's hard, use the 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 properly control the exhaust stroke and frequency, aiming for fewer exhausts and, if possible, a shorter exhaust stroke. Additionally, reduce the amount of vulcanizing agent. Secondly, the molding mold temperature for silicone hoses can be slightly increased, but the temperature should not be too high to avoid edge bursting. If wind pockets (bubbles) and white spots occur, extend the vulcanization time.
In summary,Silicone TubeSilicone tubes produced by manufacturers typically have a hardness of 30-80A, with 40A and 60A being common. Some specific hardness requirements are also available for special production needs.
