How to identify the quality of silicone products?

How to identify the quality of silicone products? With the increasing application of silicone products in various fields, consumers have higher requirements for their quality. The application of silicone products in daily life is becoming increasingly widespread, but how to identify their quality is a subject of study.

1.Observe the appearance

High quality silicone products have a smooth and delicate surface, without obvious bumps, bubbles, cracks, or color differences. Check if the corners of the product are neat and if the edges are smooth. If surface roughness and defects are found, it is likely to be a low-quality product.

2.Hand feel test

High quality silicone products have good elasticity and toughness, with a soft and smooth feel. You can gently squeeze it with your fingers to feel its resilience and softness. If the hand feels hard and has poor elasticity, it may be due to the use of low-quality materials.

3.Smell recognition

High quality silicone products should be odorless or have a slight odor. If you smell a pungent odor, it may be due to the addition of inferior materials or harmful substances during the production process.

4.Combustion test

You can ignite a small amount of silicone products with fire and observe the combustion situation. High quality silicone only produces a small amount of white smoke when burned, and the ash left after combustion is white powder. If a large amount of black smoke or viscous substances are produced, it indicates that the material may contain harmful substances.

5.Temperature resistance testing

Silicone products usually have good high temperature resistance. You can test the product by placing it in hot water to observe whether it has deformed, discolored, or produced any odor. High quality silicone products should remain stable under these conditions.

6.Certification and Reporting

When purchasing silicone products, you can check if the product has relevant certification marks, such as FDA, LFGB, etc. These certifications can serve as a reference for product quality. Meanwhile, if the product comes with a testing report, it can also serve as a basis for purchase.
