No matter how to explain and cover up the colloidal products, they can't cover the thick chemical compounds. When it comes to chemicals, most of them are related to environmental protection hazards, and neither plastic nor rubber can cover them, while rubber sealing rings are different. But generally speaking, most of the friends of colloidal products are pure in certain preventive psychology, so we need to elaborate the rubber sealing ring materials The method of qualitative discrimination.

At present, there are many household products, medical devices and electronic accessories in the rubber sealing ring industry, which are made of silica gel. Silica gel is different from other types of rubber, which mainly contains silica, silicone resin, silicone oil, blending vulcanizer and the substances added to the color rubber do not contain harmful compounds. The silica gel material is still pure in certain reference materials. For example, in order to save costs, silica gel products manufacturers use low-cost raw materials, raw material suppliers add catalysts to improve efficiency, etc., so the methods to truly identify the authenticity and quality are as follows:

Rubber seal ring color: rubber seal ring can be mixed with different colors according to the international Pantone color number, so there is no difference at all from the color and there is no defect after the appearance treatment, but the main thing is to stretch to see whether the rebound will appear white or transparent phenomenon, if there is that material may belong to the common material!

Rubber seal ring feel: rubber seal ring feel is very important. Silica gel products are very important in stretching, rebound, deformation and toughness. If the above properties are achieved, they are basically high-quality materials. Generally, they are used for high-end products and brand products such as: (brand official website silica gel mobile phone protection case) and other products!

Open fire burning rubber seal ring: this method is very effective. Generally, the high-quality rubber seal ring material is different from other rubber materials after burning, and will emit white smoke. After burning, the product surface will appear white fog phenomenon. After burning completely, it will finally appear white powder, completely colorless and tasteless, while different materials will appear yellow to finally appear black residue.
