Correlation between hardness and elasticity characteristics of woven silicone tubing

Time:2024-01-24Page views:1194

Woven silicone tubingIt is a linear polymer elastomer containing silicon oxygen bonds, therefore it has high thermal stability. It has excellent resistance to ozone aging, oxygen aging, light aging, and weather aging, as well as excellent electrical insulation performance, mold resistance, and high breathability. More resistant to cold and heat than plastic, its performance remains unchanged between -70 degrees Celsius and 250 degrees Celsius above zero. Colloidal materials are concentrated from silicic acid and rarely react with any acid under normal conditions. Alkali salts undergo chemical reactions, are non-toxic, odorless, and have excellent high-temperature resistance, making them environmentally friendly materials.

The difference between the hardness and elasticity of silicone tubing is that these two characteristics are related. Simply put, elasticity is the ability to recover instantly, while hardness is the ability to deform over a long period of time under pressure. The tensile stress and hardness of woven silicone tubing increase with the increase of crosslinking density, and traditional vulcanization systems can achieve higher modulus stress and hardness. For rubber materials with a temperature above 80 degrees, in addition to reinforcing agents such as carbon black, some resins can also be added, and some hardeners can be added. The change in hardness may be caused by increasing cross-linking density or changing the increment agent or processing oil, and there are many ways to achieve it, but all of this depends on the desired results.

Woven silicone tubing can be used as a good electrical insulation sealing and liquid transportation material, with a wide range of applications. It can be used to produce many model products and industrial supporting products. Due to its non-toxic nature, non adhesive properties with other materials, and ability to withstand multiple cooking and disinfection, silicone rubber is widely used in the medical and food industries. In addition, due to the fact that the use of silicone tubes mostly involves the food and pharmaceutical industries, regulatory efforts are also strong.
