No matter how you explain and cover up the colloid products, they cannot cover up the strong chemical substances. When it comes to chemicals, most of them are related to environmental hazards, which cannot be covered up by both plastic and rubber. However, rubber sealing rings are different. However, when it comes to colloid products, most friends still have a certain precautionary mentality. So here we have to explain how to distinguish the authenticity of rubber sealing ring materials.

At present, there are many daily necessities, medical equipment products and electronic accessories in the rubber sealing ring industry that are made of silicone. The difference between silicone and other types of rubber is that the chemical composition is different. It mainly contains white carbon black, silicone resin, silicone oil, mixing vulcanizer and color glue. The added substances do not contain harmful compounds. There are still certain fake substances in the silicone material. For example, silicone product manufacturers use low-priced raw materials to save costs, and raw material suppliers add catalysts to improve efficiency, etc., so the real method to distinguish the authenticity and quality is introduced as follows:

Rubber sealing ring color: Rubber sealing rings can be mixed with various colors and can be mixed according to the international Pantone color number, so there is no difference in color at all, and there is no flaw after the appearance treatment, but the main thing is to see whether the rebound will appear white or translucent after stretching. If there is, the material may belong to ordinary material!

Rubber sealing ring feel: The rubber sealing ring feels very heavy Yes, silicone products are very important in terms of stretching, rebound, deformation and toughness. If the above performances are achieved, they are basically high-quality materials. Generally, they are used for high-end products and brand products such as (brand official website silicone mobile phone protective case) and other products. They are widely used!

Open flame burning rubber seal ring: This method is very effective. Generally, high-quality rubber seal ring materials will emit white smoke after burning, which is different from other rubber materials. The surface of the product will appear white mist after burning. After complete burning, it will be white powder, completely colorless and odorless, while different materials will appear yellow and finally black residue.
