How to judge the quality of a silicone product?

Release time:2020-12-18

1. Whether the product's self-removing burrs feel rough to the touch, the size of the mold clamping line selects the mold work of the product, and the mold work selects the overall effect of the product. Self-removal is very important!


2. In terms of application, good silicone products are not easy to be deformed and not easily distorted when pulled, and are elastic and beautiful in color; while poor silicone products are easy to fade and deform, and are not resistant to explosion and are very simple to age.


3. Hardness and constant elongation stress. Hardness and constant elongation stress represent the important goals of the rigidity (rigidity) of silicone materials, and both are the forces required for certain deformation of silicone products. It is also a way to differentiate the quality of silicone products.


4. In terms of characteristics and feel, the resistance and elasticity of silicone products are very good. They are not deformed by external forces, and the hand feels smoother, while fake silicone products are deformed and feel rough.


5. In terms of characteristics, silicone products are non-toxic, tasteless and colorless products with good texture and no harm to the human body. However, it is difficult for ordinary fake silicone products to achieve these effects. fake and inferior silicone products are generally toxic and impactful. The nose smells, and it's rough!


6. The raw material of silica gel is non-toxic and tasteless, but the raw material will show a little gum smell when the vulcanizing agent is added in the process of high temperature oil pressure molding by the silicone manufacturer, but it will gradually disappear after the second vulcanization and long-term storage! So no The smell is normal!


7. Look at the color. When we buy silicone products, we first look at the color. The color with good quality is more beautiful. The surface is smooth, and it feels good when touched by hand; while the poor silicone product feels rough to the touch and the color is also It's turbid.


9. Smell the smell. When you smell the silicone products, there may be a little smell due to the residue of the vulcanizing agent, but this is also normal. Generally, the smell will be completely eliminated after being placed in the air for a few days; while the poor silicone products have the smell Smelly, unpleasant nose.


10. At the same time, we can also distinguish genuine and fake silicone products through the convenience of flame incineration. It is also very effective. The fake silicone products emit black smoke when incineration, and the remainder is black powder. No matter what color the real silicone products are White smoke is emitted during incineration, and the residue from incineration is white powder.


11. Wear resistance, abrasion resistance is possessed by the production and molding of silicone products. The surface of silicone products can suffer loss. Good silicone products generally rarely rub off the surface of the product due to external elements, and do not affect the appearance of performance. Text, color. The characters on the surface of inferior silicone products are abbreviated.
