What Is The Difference Between A Silicone Patches And A PVC Patches?

Silicone patches are made by heating liquid silicone oil and solid silicone in a mold through a vulcanizer. It is usually made by reacting sodium silicate with sulfuric acid and after a series of post-treatment processes such as aging and acid bubbles. Silicone is insoluble in water and any solvent, non-toxic and tasteless, eco-friendly, stable in chemical properties, and does not react with any substance except strong alkali and hydrofluoric acid. Various types of silicone have different microporous structures due to different manufacturing methods. The chemical composition and physical structure of silicone determine that it has many characteristics that other similar materials are difficult to replace: high adsorption performance, good thermal stability, stable chemical properties, and high mechanical strength.

The PVC rubber patches trademark is mainly a plastic product made by dropping a liquid material into a mold using a plastic dropping process, heating, baking, and cooling after a period of time, and finally pouring the mold. The main components of PVC rubber seal are DNP oil, PVC powder, stabilizer, and soybean oil.

The main difference between the silicone trademark and the PVC lables is that the material feels different. The silicone rubber has a higher eco-friendly factor, which can be tested by the European Union. The PVC rubber lables has a stronger smell and the eco-friendly factor is not high. It is more common in the domestic market
