1. Strong acid and alkali: Silicone tube that is resistant to abrasion and high pressure will be corroded under the condition of high concentration of hydrochloric acid and high concentration of nitric acid (high concentration will be affected, low concentration will work normally) Silicone is an elastic material, not a solid Materials, conventional materials cannot withstand strong acids.

Strong base refers to chemical substances such as hydroxide and potassium hydroxide. If it is in contact with the wound silicone tube for a long time, the chemical formula of the silica gel will be unstable and decomposed, but the wound silicone tube with a pH value lower than 6 can work normally.

How to solve these problems can be solved by adding a fluorosilicon material between the materials during the extrusion of the wound silicon tube. This can change the molecular structure of the wound silicone tube and achieve a certain function. After adding the fluorine silicon to the product, You can completely avoid this situation without having to worry about strong acids and bases.

2. Oily substances: High-pressure resistant silicone tubing is not in contact with most concentrated oils or compounds, but fortunately, the wound silicone tubing basically does not need to be exposed to high concentrations of oily substances on the fiber because the oily substances will melt it, such as Long-term exposure to gasoline silicon will slowly decompose and volatilize, but these problems can be solved by adding inert materials such as fluorine to the product.

Silicone tubes, such as automobiles, can be flexibly used in gasoline engine oils because they add this material.
