How to judge whether the seal ring is made of silicone rubber?

Apr 10, 2023

In the silicone rubber products industry, there are many daily necessities, medical equipment products and electronic accessories products that are made of silica gel. The difference between silica gel and other types of rubber is the chemical composition. It mainly contains silica, silicone resin, silicone oil, mixed sulfurizer and the substances added to the color rubber do not contain harmful compounds. However, the silica gel material is still pure in certain fake substances. For example, the silica gel product manufacturer uses low-cost raw materials to save costs, and the raw material supplier adds catalysts to improve efficiency, etc., so the methods to truly distinguish the real from the fake and the quality are as follows:

1. Color:
Silicone rubber products can be mixed with different colors according to the international Pantone color number, so there is no difference in color and there is no defect after appearance treatment, but the main thing is to stretch to see whether the rebound will appear white or transparent. If there is any material, it may belong to ordinary material!

2. Feel:
Feel is very important. Silicone products are very important in terms of tensile, rebound, deformation and toughness strength. If the above properties are achieved, they are basically high-quality materials. They are generally used for high-end products and brand products.

3. Open flame combustion:
Generally, the high-quality silica gel product material will emit white smoke after burning, which is different from other rubber materials. The product surface will appear white fog after burning, and will finally appear white powder after complete burning, completely colorless and tasteless, while different materials will appear yellow to finally appear black residue.
